Roboflow | Solutions Architects, Implementation Engineer, Developer Advocate, Full Stack Engineers | Full-time (Remote, SF, NYC) | https://roboflow.com/careers?ref=whoishiring0725

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform [1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.

Over 1 million engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models [2]. We are pushing forward the CV ecosystem with open source projects like RF-DETR [3] and Supervision [4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog [5] and YouTube channel [6].

We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We raised our Series B round at the end of last year, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >500 organizations using our product.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. 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.

Autokroma.com | C / ffmpeg / codecs / GPU / AI dev workflows | Full-time | HYBRID | Porto / North of Portugal

We do audio video software : video editing plugins, web panels, GPU visual effects, encoders, decoders, AI assisted development & testing. All levels are welcome but be sure to make me understand what are your current capabilities. You will work close to the code, user requests, whole UX in general, I try to minimize the layers between developers, products and final users.

If any of those topics are of interest to you, and you're around Porto to meet me : send me an email, the first part of the email is "contact" and after @ the domain name. Tell me your story, what you're looking for in your life now, a previous bad work experience you'd like to avoid and a good work experience that inspires you for the future.

Phrasing | https://phrasing.app | Elixir + Clojure + Swift | Technical Co-founder | EU REMOTE (Amsterdam/Lisbon)

I’m going to be honest with you: I want to be the best in the world at what I do. I’m not there yet, but I know I am willing to put in the hours, and fail as many times as it takes for me to get there.

For that reason, Phrasing to me is more than just a language learning application. It’s a chance to do something different. A chance to build a product that pushes humanity forward. A chance to build experiences that are genuinely delightful. A chance to build a company that can inspire.

I’ve built the current version entirely myself (not even a single like of AI generated code). On the good side: the product is working, I’m using it every day to genuinely learn 18 languages, and the user base is growing. On the bad side: the onboarding flow needs a lot of work, the pipelines keep breaking, and the maintenance burden is too much for me to handle alone and make progress on the product at the same time.

I’m looking for an engineer to join in a co-founding capacity and help me build something truly great. You would assume responsibility of the backend Elixir application, while I spearhead the various frontends (web, mobile, design, marketing). You’d make sure every task succeeds, keep queries times minimal, and optimize the crap out of the data and the infra. On the product & leadership side—we would collaborate on everything. I believe strongly that the best ideas are born of two minds.

And to tie it all together, I’m looking for someone else that wants to be great. Someone who wants to do things differently, someone who isn’t afraid to chase their dream and take their shot.

No experience for this role is necessary. All I care about is that you’re competent, passionate and hungry.

If you feel like this is you, then send a well written introduction to hn [at] phrasing [dot] app. Any AI applications will be ignored and the senders blocked.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We’re creating robots that autonomously construct buildings. We design all of our hardware and software in-house in central Amsterdam, starting with autonomous bricklaying robots.

Building a robot like this means solving all sorts of interesting challenges: figuring out the robot's position with sub-mm precision; navigating autonomously around the building site; automating measurement and calibration of new robots; lots of distributed systems and so on.

Our robots are now continuously deployed on customer sites and we are earning real money as a masonry contractor. The full team is more than 60 people and we're growing rapidly to meet demand.

Our stack is mostly: Rust, TypeScript, Python, NixOS.

Some open roles:

- Software Engineer, Full Stack

- Software Engineer, Controls

- Software Engineer, Machine Vision

- Assembly/manufacturing technicians and robot operators

https://www.monumental.co/jobs

P.S. When we say full stack, we really mean it. Bolting things together, mixing mortar, embedded firmware, (software) build systems, React components and everything in between. Happy to answer questions.

AWS | Embedded Firmware Engineer | Austin, TX or Cupertino, CA | Full-time

I'm a team lead engineer at Annapurna Labs, the small company-within-a-company that designs AWS custom silicon. My organization designs and runs the Trainium and Inferentia machine learning (ML) accelerators. Our team is hiring engineers to help build the on-chip firmware stack for new and existing chips. This firmware is the lowest layer of the Neuron software stack; you can think of it as implementing a silicon-accelerated virtual machine that the Neuron compiler targets.

This is a bare metal, system software-oriented role (think C/C++); no specific ML experience is needed, but if you have experience writing GPU/CUDA kernels or microcode for other systems, we can definitely put your experience to work. If you're interested in machine learning, you'll be adjacent to people who have tons of experience with high performance compute, chip design, and ML algorithms.

We offer relocation to Austin or Cupertino; the team is split evenly between the two sites.

Ping me if you're wanting to chat about the team or the role: ghilliar -at- amazon.com. I'm an embedded systems engineer and I don't bite :)

Lore (https://careers.lore.co) | Software/Machine-Learning/ Data Engineers + More! | Full-time | REMOTE (US)

The company: Modern healthcare excels at treating fallout, but it struggles to address triggers—because it wasn’t built to. Yet intervening at these trigger points isn’t just how we stop rising demand; it’s how we create more health and happiness. We started Lore to build a new kind of care: a continuous, holistic approach that supports people whether they’re flourishing, struggling, or somewhere in between. We call it preemptive care.

The role:

  - Small, cross-functional squads that own the full vertical slice of a problem space.

  - No product or project managers—you're the one driving decisions and implementing them in a fast-paced, ambiguous environment.

  - Working fully remote across the US means you need strong written communication and the ability to work asynchronously. Whether you're deep in technical details or connecting ideas across disciplines, clear communication is essential.

  - We value the expertise you bring, but when new information comes along, we also need you to adapt quickly, challenge old assumptions, and embrace new ideas.

  - If you thrive in an environment that rewards bold ideas, continuous learning, and active engagement in every aspect of the business and want to help people become more agentic, Lore might be the perfect place for you.
