Ask HN: Who is hiring? (September 2025)

Narrative I/O | Senior Backend & Frontend Engineer positions | New York, NY | Full-time | REMOTE (4-hour overlap with EST for backend, US & Canada for frontend) | $120k to $200k USD | https://narrative.io/

Narrative has been building a data collaboration platform designed for simplicity and ease of use since being founded in 2016.

Our primary strength is functioning as a data marketplace where we differentiate ourselves by automatically standardizing data, making platform data accessible through the Narrative Query Language (NQL), giving data providers the ability to define row-level access and pricing policies, and making it easy to deliver data to a variety of destinations using our "Connector Framework".

We operate two flavours of our platform: An AWS-based implementation that runs on our infrastructure, and a Snowflake-based version running inside the user's Snowflake account.

We are a small, remote-first team looking for great developers who want to jump in and take major systems and user-facing features from design to launch. While the company's headquarters are in NYC, the development team currently includes engineers working from the US (California and New York), Canada (Alberta, British Columbia, and Québec), Poland, and Serbia.

In brief, the technologies we use are:

- Backend: Scala, Spark, Apache Iceberg, Apache Calcite, Cats, Cats-Effect, Http4s, FS2, Doobie, Deequ, Axolotl, BentoML, and HuggingFace Transformers.

- Frontend: Typescript, VueJS, Nuxt, Vite, and Cloudflare Pages.

- Operations: AWS (ECR, ECS, EMR, RDS, S3, etc.), Datadog, Docker, Terraform, with some burgeoning use of EKS/Kubernetes.

Job postings and more on information about our team and culture are available at: https://jobs.narrative.io/

Strum AI | Founding/Lead Engineer | https://www.linkedin.com/company/strum-ai/

At Strum, we're reimagining technology that powers global supply chain using a fresh AI-first approach. Most supply chains are still stuck with Excel or enterprise tools that take months (and $MM) to adopt. Our mission is to lower that barrier — making it possible for any business, big or small, to access modern forecasting, inventory, and planning solutions in days, not months. We’re on our journey to democratizing supply chain technology. As our first engineer, you’ll be working with the founders (former Supply chain/tech directors at Amazon who have built key components of Amazon's supply chain) to develop the core product from the grounds up (involves application of LLMs, deep learning, and optimization). If you have mid to senior level experience in software development, have built SaaS applications, understand ML-Engineering, and love building 0->1 products, we would love to talk to you. Please reach out to us at: careers@strum-ai.com.

Location negotiable.

Link11 | QA Engineer | Remote (EU time zone) | Full-time | https://www.link11.com

As one of our QA Engineers, you'll be the guardian of product excellence - thinking like a hacker, testing like a detective, and ensuring our complex systems work flawlessly in the wild. You'll go beyond finding bugs to anticipating the unexpected: edge cases, weird component interactions, and those "no user would ever do this... but what if?" scenarios that separate good products from great ones.

What You'll Own:

* Design battle-tested strategies that catch issues before customers do

* Build automated test suites that scale with our ambitions

* Hunt down bugs across complex component interactions and configurations

* Partner with dev teams to ship quality at speed

* Be the voice of risk assessment when it matters most

You Should Have:

* Critical thinking that connects dots others miss

* Deep web tech knowledge (HTTP/HTTPS, DNS, SSL/TLS, CDN)

* Automation chops (Python, JavaScript, Bash)

* Experience with test methodologies and writing bulletproof test cases

* Debugging skills that turn logs into insights

* Communication skills that turn complex issues into clear actions

Why Join?

You'll be testing cybersecurity products that defend critical infrastructure against DDoS attacks – a single bug could mean the difference between stopping an attack in <10 seconds or watching a bank, power grid, or hospital go offline. This isn't just QA – it's cyber defense at the highest level.

If breaking unbreakable systems and ensuring bulletproof security for critical infrastructure sounds like your kind of challenge, come lead, code, and conquer with us: https://www.link11.com/en/blog/jobs/qa-engineer-remote-first...

Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We just raised a $50M Series A and are now expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We're scaling rapidly in terms of # of users and are especially keen to talk to seasoned backend, data and infrastructure engineers.

Even if we don’t have a role out for your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

TAHO | Rust Engineers | REMOTE (US) | Full Time

Crabby Devs Wanted - TAHO is hiring Rust Engineers

If you live for low-level performance wins and distributed systems wizardry, you’ll feel at home here.

Apply here: https://www.indeed.com/viewjob?jk=bfb68e11b34a2ae9

We’re building the first cloud performance layer — think AI workloads that run 30x faster at 90% lower cost.

At TAHO you’ll: Hack on Rust + WASM to design resilient, high-throughput runtimes. Build low-latency comms (gRPC, libp2p, or your own P2P magic). Ship code that directly bends compute costs and scales across cloud, edge, and HPC.

This isn’t a “maintain legacy” gig — it’s greenfield infra at startup speed with equity, full remote, and the chance to shape a category-defining system.

If optimizing runtimes and squeezing every cycle out of hardware gets you hyped —> we want you.

Y Combinator (yes, the people who run this site) | Full stack web and AI | San Francisco | Onsite | Fulltime

YC itself hires software engineers from time to time. Many people don't know that YC has a small but very important software team. We run several websites - not just this one, but also workatastartup.com (the main way YC companies hire), a social network for YC founders, and the core infrastructure that YC itself runs on.

Recently, we've been spending most of our time building our own AI agents. Over the last year, YC has mostly funded AI agent companies, so it's been cool to go really deep building our own AI agents too. We're building agents to automate every aspect of what we do, and pushing the limits of what's possible with the current models to do it.

An unusual aspect of being on the YC software team is that you'll get full access to the YC program, founders and partners. The YC batch runs in the same building we work out of, so there are talks with famous founders happening most nights, right downstairs in our building. If you want to start a startup someday, working at YC would be an excellent jumping off point - several YC companies have come from team members who decided to start their own company.

YC works fully in-person in SF. We're happy to help you move here if you're in the US already. Unfortunately we can't sponsor new visas, but we're happy to transfer existing ones.

YC offers highly competitive compensation and benefits.

You can apply online (https://www.ycombinator.com/careers) or just email me at jared@ycombinator.com

Komodo Health | Applied AI Engineer | Full-Time | $200-$253k + equity... | SF/NY Once-a-month-few-days / Remote US. Can sponsor.

Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.

We have an exciting product, marmot, that is AI-native, both in the interface as well as in development, and want to carefully grow high productivity teams around this offering. AI integrated with Komodo's data is giving some of the most unique, real world insights any of us has seen come out of the new LLM era. Our product was just featured on Times Sqaure too! https://www.linkedin.com/posts/komodo-health_last-week-our-d...

We are looking for highly independent individuals, who can work in a new, small, but empowered team. What will you be bringing? - Proven experience working on Agentic systems that solve real problems OR Some evidence you have the "instinct" Andrew Ng mentions as the differentiators of successful Agent builders.

The new LLM/Agent era is... different.

Perks will include annual conference trip, periodic travel to SF/NY for on-site, Executive Coaching, etc.

Friendly Captcha | Data Engineer - Bot Protection | REMOTE within EU | PART-TIME or FULL-TIME | Office in Munich, Germany | https://friendlycaptcha.com

We provide privacy-friendly and accessible anti-bot solutions that don’t annoy users with tasks like clicking fire hydrants. We make the internet a bit better every day by winning over customers currently using Google reCAPTCHA.

We’re a growing, profitable, fully bootstrapped company. Our revenue mostly comes from medium to large European enterprise and governments.

We’re looking for an engineer whose focus will be on using data to improve our bot detection and protection. Telling apart bots from genuine users is vital to our product.

At our scale we are looking for generalists more than specialists. The role is more about enabling for easy experimentation, data exploration and being creative in anti-bot approaches, than building the perfect ETL pipeline.

Our engineering team is fully remote across Europe, we meet up in person a few times per year. You can work either 4 or 5 days per week, fully remote or (partially) from our Munich office. Please note that we ONLY consider candidates located within the EU/UK/EEA/Switzerland.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications.

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our app to petrichor

* a mature product (the code base is over eight years old and we've found and fixed a lot of the sharp edges around core login use cases; however there are plenty more features to add)

* founder-led; the CTO is an engineer who still writes code

* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already

Our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure. We are profitable but raised money in 2023 to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).

Stealth Solar Tech Startup | Remote (EU-friendly) | Full-time or Contract

We are a well-funded stealth startup building a B2C platform to radically reform the U.S. residential solar industry. Our mission is to combat pervasive consumer distrust and inefficiencies by empowering homeowners with a transparent, high-fidelity, and interactive 3D solar design tool. We are a small, dedicated team working closely with an established industry partner for rapid, real-world testing and iteration.

We are looking for a Senior 2D/3D Computer Vision Engineer to build the core technology that makes our platform possible. The central challenge is to automatically generate clean, geometrically accurate, and simplified 3D roof models from raw aerial Digital Surface Models (DSM) and RGB data. Your work will be the foundation of our user experience, replacing the opaque and slow manual processes that dominate the solar industry today.

As the owner of this domain, you will ideally:

• Define the Process: Take charge of the entire ML pipeline, from R&D to production. This includes refining the annotation process and enhancing our existing Three.js-based 3D annotation tool to build a high-quality, large-scale dataset.

• Build the Models: Research, develop, and train a suite of models to handle roofprint segmentation, structured prediction of planar roof wireframes from point clouds, and detection/classification of roof obstructions (chimneys, pipes, windows, etc.).

• Ship to Production: Engineer a scalable and robust inference pipeline that can process new properties on demand.

Our stack is Python, PyTorch, FastAPI, Rasterio/GDAL, and JavaScript/Three.js for the annotation tool. We are looking for a pragmatic and experienced engineer who loves tackling complex 3D vision problems. You should be comfortable with both 2D and 3D data (especially point clouds and geospatial imagery) and have a proven track record of delivering end-to-end ML solutions.

To apply, please email vlad@design.solar.

Who's a good fit:

* If you've always thought about starting a company, but for whatever reason (funding, life, idea), this is a great opportunity to be part of the founding team. We're 2 people right now.

* You enjoy understanding customer problems and their use cases, and then figuring out the best solution (sometimes technical, sometimes not) to their problems.

* You want to help figure out what a company looks like in this AI era.

* You enjoy teaching and sharing knowledge.

Questions, interest, just email jobs@polarsky.ai.

ko-br | cofounders hunting and founding members across design, engineering, research and business development | https://ko-br.com | Onsite (SF, USA)

Looking for another technical cofounder, a commercial cofounder (work closely with Stacey, our advisor and ex-CCO of universal Robots) and founding members. If interested, let’s catchup over coffee in sf in sep.

P.S. we are closing our pre-seed round soon so don’t worry about our runway :)

It’s a shame that we have unbelievably good hardware like collaborative robots (cobots) that could transform warehouses and yet they still struggle with basic tasks like unloading mixed pallets. Why? Because today's software can't handle real-world chaos.

That's where we come in. At ko-br, we're building the AI brains that make robots truly adaptable. Our physical AI models tackle messy, unstructured problems starting with depalletizing of mixed boxes in dynamic warehouses. Think real-time adaptation to shifting pallets, mixed SKUs, and unexpected failures.

We're a deep tech startup at the crossroads of AI, robotics, and human-machine interface. While warehouses are our first battlefield, our core mission is physical AI. So you need to be comfortable with the idea of pivoting to other sectors like education (ex: building robots for schools and universities).

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?

We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen

Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.

Three open roles (apply below!):

Bubblehouse | Fully REMOTE | Full-Time | $250k | Principal Engineer

Bubblehouse is a fast-growing custom and private loyalty platform. Headquartered in NYC, the entire team is fully remote and spread across US and Europe. We power loyalty programs for large brands, including household names.

We’re again expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

Tech-wise, we’re running on Golang, and using custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site), CA

I'm the cofounder & CTO of Krea (https://www.krea.ai).

We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives.

Small team (~20); millions of active users; and raised over $83M from top Silicon Valley investment firms.

We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.

The job:

- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.

- Build data pipelines and deploy ML models to make sense of raw data (e.g. find clean scenes within videos).

- Learn ML engineering from world-class researchers on a small tight-knit team. As you’re building data pipelines, you’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions of Krea users.

- Play with massive amounts of compute on huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.

Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)

You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for deep experience with distributed systems, kubernetes, and existing ML or data experience (but not required!). Cool side projects are a green flag.

Phrasing | https://phrasing.app | EU Remote | Co-founder

Phrasing is the best way to learn and maintain multiple languages [1]. With support for over 120 languages, science-based methodologies, and a beautiful custom built UI, Phrasing make’s it easier than ever to learn a language… or 10.

Phrasing is built with Elixir on the backend (lots of Broadway, FLAME, Nx and Scholar) with a ClojureScript front end. Everything is stored in a single Postgres database hosted with neon. I’m moving some code to a commons library, with the end goal of using Clojure as an isomorphic solution to run the same code on web, server, and mobile (<1% of the codebase, just the critical logic). The front-end is moving from Reagent+React to HSX+Preact+Preact Signals, although that’s going to be a long and slow migration.

Phrasing is my attempt to do something different [2], from both a product and a business perspective. No investments, no hyper scaling, no growth hacking — just tripling down on building the most effective application to learn a language.

Phrasing is launched, live, has some DAUs and MRR. However, long ago I’ve reached the limit of what one developer can do. I’m looking for someone to

  - come on board and take over the entire Elixir codebase
  - watch the Broadway Pipelines, and not sleep if there are any failing checkpoints 
  - optimize request times, reduce database pressure, and speed up extraction times
  - work with me to restructure things to reduce costs/complexity
  - work towards training novel embedding spaces, custom classic ML/NLP models, and long term algorithmic improvements to the SRS [3]
  - see this as a fun challenge, and have enough ownership of the product that I can focus on some user facing developments [4]

To apply, please send an introduction hn at phrasing dot app. I will not be interviewing until the 12th of September, and no priority will be given to earlier or later applicants, so there is no rush. A sincere, well-written introduction is your best way to get an interview. No experience is required for this role, so long as you’re competent and hungry.
