ICEYE | Platform Software Engineers (Senior/Staff) | Espoo, Finland / Berlin, Germany | HYBRID | Full-time (relocation support)

ICEYE builds and operates the world's largest SAR satellite constellation. I lead Platform: three teams (Core Platform, Developer Enablement, SRE) that run the foundation engineering teams ship on.

Why it is hard: we run Kubernetes in public cloud, in our own data centers, and inside customer sites that are air-gapped. Same platform, same tooling, no internet. Satellite tasking and image delivery run on it, so downtime is not an option. Stack: Go, Python, K8s, Terraform/OpenTofu, Istio, Vault, LGTM, OpenTelemetry.

We are hiring in Espoo and our Berlin office:

- Staff/Senior Platform and DevOps Engineer: own the Kubernetes platform across cloud and on-prem, build & extend tooling in Go, set technical direction. https://jobs.ashbyhq.com/iceye/cf6ba0e9-a750-4ee7-9b0a-8cb51...

- Senior/Staff Platform Observability Engineer: define the direction for our observability for all engineering teams, build tooling around it. https://jobs.ashbyhq.com/iceye/19a2709c-1e6d-4c8d-958a-2f07f...

- Senior Software Engineer (Developer Enablement/Experience): build the developer tooling for engineering teams. Python/Go, K8s, IaC, partner directly with developers. https://jobs.ashbyhq.com/iceye/1ffce4d4-4088-4336-9007-622dc...

What we look for in all of these positions: product-mindset, all these positions have impact across ICEYE, pragmatism and empathy for the developers you serve.

ALBERT | REMOTE, ALMOST ANYWHERE | New grads who’ve shipped AI features (max 2 years out of school) + Principal/Distinguished engineers for net-new consumer products | senior track up to ~$750k cash plus meaningful equity

Consumer fintech, 20M+ users, profitable 4+ years, 3.6-year average tenure. People stay because the work is good and the people are sharp.

We hire like a barbell: exceptional builders at the top, exceptional builders at the start, nothing in the middle.

NEW GRADS (0 to 2 years out): We don’t care about your school or GPA. We care that you’ve already shipped something with an LLM in it that real people used, and you can show us the link. You haven’t learned to hedge or wait for a ticket yet. Come here before a big company sands that off you. You’ll ship to 20M users in your first weeks, working directly with the principal engineers below.

PRINCIPAL/DISTINGUISHED: Building net-new consumer products from zero. Top fraction of a percentile in craft. Builds for fun and ships prototypes on weekends. Owns 0 to 1 end-to-end. Founding engineer experience is a strong signal. Allergic to politics and bureaucracy.

Both tracks: comp that beats the market (base, year-end bonus, meaningful 401(k) match, meaningful equity in a profitable unicorn), platinum PPO for your whole family, small senior-heavy teams with no layers, full transparency on business metrics, catered lunches, wellness stipend, offsites.

Stack: python, claude, postgres, react.js / react native

Email recruiting@albert.com with your track and a link to something you built. We read every application and reply within a few business days if there’s a fit.

Search Atlas | Product Engineer (PM) | REMOTE (anywhere, EST hours) | Full-time | $23-34/hr

We're ~160 people building an AI marketing platform. Our main product, OTTO, runs a site's SEO on its own: it reads live search data and ships the technical and on-page fixes itself. Customers include Autotrader, Hyundai, P&G and Vendasta.

You use Claude Code or similar daily.

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer

We’re a small team across the US and Europe. We build the platform that household-name brands use to run their own loyalty programs.

We write Go and run our own database engine on top of local key-value stores. We keep storage and compute on the same dedicated machines and read straight from mmap’ed pages. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

We write our JavaScript by hand, have zero lines of React, and render HTML server-side like it’s 2005.

We’re looking for someone who knows the web platform well and can reason all the way down to CPU caches. You’ve spent years building across different stacks and have opinions about the tradeoffs you made. We’d love to see something you built that you’re proud of, and hear why you built it that way.

We pay $200–250k a year, all cash. You’ll need to be available from 9am to noon New York time.

Lumen Labs | Robotics/Hardware Engineer, Simulation Engineer | San Francisco, CA | ONSITE | Full-time | $150k–200k + equity | https://lumenresearch.co

Howdy! Lumen Labs is building the cognitive layer for physical AI. Nearly every major robotics effort today teaches machines by showing them thousands of hours of human teleoperation. We think that paradigm has a ceiling, and we’re working on nature-inspired architectures for unstructured environments (construction sites, mining, pipelines, battlefield). Pre-seed, backed by top VC funds and operators from robotics/AI companies. Today we run wheeled navigation, we’re dipping our toes into drones, and we’re eyeing weirder platforms like home inspection.

We’re a small team hiring two engineers who will work closely with each other and with our model engineer:

ROBOTICS / HARDWARE ENGINEER: Own the hardware and infrastructure that keeps our research platforms running: the ROS2 (Humble) stack across onboard and offboard compute, sensor integration and calibration (LiDAR, depth, IMU, encoders), the safety pipeline during autonomous runs, and getting trained policies onto real hardware. Will be hands-on with real mobile robots (UART, encoders, PWM, IMU, LiDAR), strong Python + embedded, comfortable reading code you didn’t write, and can debug hardware and firmware at the same time. Full posting: https://desert-bearskin-26d.notion.site/Robotics-Engineer-Ro...

SIMULATION ENGINEER: Own “the gauntlet,” our test library for putting new architectures through their paces: a Gymnasium-style interface on both sides (environment and model) so anything built to spec is compatible with everything else. Mostly MuJoCo and Gazebo today, moving toward Isaac Sim, and some other more bespoke sims. You will be building task simulators for training and testing and keeping them running (GPS-denied drone nav, construction sites, boat cleaning, forklifts, abstract control), including physics, honest sensor models, digital twins of our real platforms, domain randomization, and the sim compute. Dungeon Master. If you have built or substantially rebuilt a simulator of some kind (robotics/RL is closest, but a physics-based game, scientific sim, or flight sim mod counts) this would be a good role for you. Comfortable with the Gymnasium/dm_control way of thinking, can pick up GPU-vectorized sim (MJX, Isaac Lab, JAX) quickly, and test-driven. Full posting: https://desert-bearskin-26d.notion.site/Simulation-Engineer-...

Email hi@lumenresearch.co, mention HN and which role, and tell us about a project you’ve built. If you can link to a trained policy running on real hardware (robotics) or a simulator you built or fixed and something you trained inside it (sim), you go to the top of the pile.
