Elucid builds FDA-cleared AI software that analyzes cardiac CT scans to characterize plaque and predict heart attack and stroke risk. The world's best cardiologists use our output to make treatment decisions for real patients.

Uber | https://www.uber.com/ai-solutions | Senior Product Engineer | Full Time | Amsterdam, The Netherlands | Hybrid

We’re building a complex data labeling platform for AV and robotics teams working with multi-sensor data: images, point clouds, sequential data, and 3D scenes.

We’re hiring a Senior Product Engineer to help us ship the core web product faster and improve the quality of customer-facing labeling workflows.

Tech stack: Vue/React, TypeScript, Three.js/WebGL/WebGPU, TinyBase, Django.

You can help us solve problems like: - Making 2D and 3D annotation workflows faster, more precise, and easier to use - Designing point cloud tiling, autosave, undo/redo, review, filtering, and issue-tracking workflows that hold up under real labeling operations - Improving performance where milliseconds matter: rendering, local state updates, preloading, and geometric operations - Shaping API contracts, data models, permissions, background jobs, and operational tooling as the platform scales

This is a senior role with high ownership on a small team. To apply, please reach out to bert@segments.ai (we recently got acquired by Uber) with a resume and mention HN in your application.

We at neocom are building shop agents for online retailers.

We are based in Munich with a strong onsite culture (not full time).

We've been in the guided selling space for the past 6 years and launched our new product, the Shop Agent, last year in November. Our customers who are already on this new product are loving it and demand more and more features.

We are now looking for founding frontend engineers who can help our engineering team (4 people + 2 starting in September). We consider our selfs as craftsman, who care a lot about quality. A lot. We have a classic TypeScript + React.js stack with a lot of cypress.

RealEstateU | Fullstack Engineer, MERN / LMS | REMOTE (UTC-01:00 to UTC+03:00) | Contract, full-time

We're a leading online U.S. real estate education provider. Our custom LMS is a large MERN platform (Node/Express, MongoDB Atlas, React, Azure) currently maintained by an external contractor. We need one senior fullstack engineer to help establish oversight and technical standards for the platform, as well as form our own engineering culture.

The work:

- CI/CD: Cut ticket-to-production from months to days. Modernize the build, tests, linting, and GitHub Actions.

- Architecture: Break a monolithic environment into dedicated microservices to enable async release schedule.

- APIs: Bolster integrations (Stripe, BioSig, Honorlock, SendGrid, Zapier) and open data up to new services.

- Frontend: Rebuild student-facing surfaces with modernized stack, ideally using a portable design system.

You: >5 years of solid React + Node on complex MERN products, fluent English, and have already embraced a constructive AI-native workflow (i.e. Claude Code / Codex / Cursor). This is an IC role where you will have significant ownership and ability to define engineering standards as we grow our in-house capabilities. This is not fractional or agency work.

You'll be given autonomy, work directly with founders + PM, and will not be micro-managed. We'll cover the AI coding plan of your choice and encourage its use with your good judgement. This is an opportunity to work on a scaled product (~100k users) with real revenue, not a startup.

Simply complete our 5-min questionnaire here and we'll reach back out to you directly: https://forms.gle/vjdnjrnDVxcsCWM76

Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.

We are currently looking for the following 4 roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.

Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, but we are super flexible overall, it will be hands down one of the best work environments you can get. Pay is competitive, and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns.

Hiring across OS, full-stack, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.

Android Systems Engineer (AOSP/BSP) - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. _Filter: send us something you built where you had to fight the OS or hardware.

Full-Stack Engineer (Apps + Backend + ML) - Everything at the platform layer. Generalist who ships end-to-end. Skill check: can build a crude-but-working facial recognition system (camera → model → DB → backend). (using existing facial recog models) Bonus for weird/constrained hardware work or running ML on edge devices. Stack: Android, Java, Python, TypeScript. _Filter: send the most useful thing you've built and used (no CRUD slop). Even better if you still use it for yourself.

Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. _Filter: photo of a board you designed or debugged, plus what went wrong.

Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. _Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.

Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.

To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. Thanks for your time!
