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 :)

Roundtable is a research and deployment company building the proof-of-human layer in digital identity. Roundtable seeks to research and build real-world Turing Tests, and to productize these developments in bot detection, fraud prevention, and continuous authentication.
We're hiring a Member of Technical Staff. This is not a typical “Founding Engineer” position. In particular, this role will involve more research than similar positions. You should be prepared to spend around half of your time on research and half on engineering.
The ideal candidate has experience in both. However, we don’t strictly require research experience as long as you have a strong quantitative background and an eagerness to learn. We do require proficiency in both web development (Javascript, Node.js) and Python.
If you're interested shoot an email to matt@roundtable.ai with your resume and a short blurb on why you're interested (note: we are unable to offer visa sponsorship at this time).

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.
We're looking for experienced FULL-STACK ENGINEERS who can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Rapid deployment and iteration of experimental software changes across firmware, control software and UI
- Modelling buildings in code and finding the right UI for operators to edit them
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity.

Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We’ve mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. 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. We also take full ownership of the product, so experience+readiness for fullstack development is a must. Core ML experience is not required and for this position, not relevant at all. The new LLM/Agent era is... different.
Perks will include annual conference trip, periodic travel to SF/NY for on-site, Executive Coaching, etc.

San Francisco (Dogpatch) | On-site w/ flexibility | Full-time | Multiple Roles, $120k–220k + equity + benefits
Why: Comms are contested. Radios make you a target, satellites aren’t guaranteed, and brittle legacy networks won’t survive future fights.
What: We’re building an autonomous maritime network — think distributed systems in the ocean—extending resilient comms, sensing and compute to the edge in high-threat remote environments.
Who we are looking for:
- Software Engineers: large-scale distributed systems, networking, system design, embedded software, DevOps rollouts. Python, C++, Rust. Bonus: SDR, mesh, security.
- Electrical Engineers: PCB layout, embedded, RF, circuits, power/batteries, electro-mechanical. Bonus: DSP.
- Marine/Mechanical Engineers: pressure vessels, subsea robotics, gliders, ruggedized design; DFM, reliability, field deployment.
You will: ship code to robots, test on the water, move fast, own big surface area, and work directly with military operators.
About Us: Our founding team includes a Navy SEAL veteran, defense industry engineers, builders, hackers, and watermen (sailors, boaters, divers, fishermen). We’re focused on real future missions — not legacy requirements. Venture-backed; public launch soon.
Eligibility for a TS/SCI security clearance is a plus. Please send a short note + resume/portfolio to jobs@reveredefense.co with subject HN – Engineering.
We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, Material Sciences, and more.

At Friendly Captcha we do one thing and we do it well: we protect websites from malicious actors and bots.
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.
If possible, we prefer to keep things simple (perhaps boring is the right word even?) - choosing an if/else rule over a neural network. Good knowledge of the web is always useful in this company. 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.

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.)

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).

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.

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.
