Tech stack includes Typescript & React for the front-end; Go (Golang) running on Google Cloud (GCP) w/ Kubernetes (K8s/GKE), BigTable, BigQuery, Solr, and more for the back-end; Java, Objective-C, and Rust for mobile; and smaller amounts of other languages including Swift, Kotlin, Dart, Python, and Ruby where they make sense.
Note that for the iOS role, we're not building apps. It's about taking things apart, seeing what makes them tick, and figuring out how to extract the data we need without negatively impacting the app experience. (Or using any private APIs!) It's part reverse engineering, part systems programming, and part library development.

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 50 people and we're growing rapidly to meet demand.
Our stack is mostly: Rust, TypeScript, Python, NixOS.
Some open roles:
- Software Engineer, Controls
- Software Engineer, Machine Vision
- Assembly/manufacturing technicians and robot operators

We're looking for a backend-leaning fullstack dev. You will be the first engineer outside of the founding team. Here is a bit more about us:
We're a seed stage AI startup backed by several top tier VCs.
We're on a mission to ensure patients get the coverage they deserve and providers get paid fairly! To do so, we're debugging core problems in the US healthcare system with a modern tech stack and AI. We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, and Harvard Business School with previous successful exits. We also have a 6+ month customer waitlist!
We're hiring our first engineer outside the founders. You'll work directly with customers to understand their needs, design the right solution, and build from zero to one. You'll own entire parts of the roadmap and tech stack while wearing multiple hats. Most important characteristics are resilience, work ethic, and curiosity. We care about slope, not where you are today. This is an opportunity to work in an insanely fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.
Things we need help with:
- Our API (https://docs.riza.io/) (Postgres / Go)
- Our account dashboard (Postgres / Go / React / TypeScript)
- Our code execution engine (Go / Rust)
- New products including code generation workflows (Anthropic / OpenAI experience a plus)
We’ve raised seed money, but the whole company is currently just me, Andrew and David working out of a converted warehouse on Alabama St. We’re second-time founders, so we know the risk we’re asking you to take and we’re prepared to compensate accordingly.

MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
