Software Engineers | All Levels

Engineers at Antithesis work across a wide range of domains, often developing their own tools along the way. They dig deep to understand how something really works -- but stay broad to ship features across the whole stack. The ideal Antithesis engineer is a generalist who loves to learn new things and will fearlessly hack on whatever is needed. The core requirements: you're smart, get things done, and a joy to work with. We're looking for Senior, Staff, and Principal Engineers to build the future of autonomous testing. No matter your particular field of experience, if you've been ambitiously building complex software and think you could be a fit; drop us a note. The Tech Some of the tech and languages we use: Nix. Lots of Nix. Nix for builds, Nix for infrastructure. Nix where you did not expect! Rust for systems programming... and C/C++ where needed. Typescript (and JS) on the front end. All the other languages also: see our list of SDKs. The Projects We're looking for top-flight engineers to help us build: A functional, reactive notebook A streaming, analytic database (Semi-) formally proven infrastructure A custom, high-performance hypervisor ...and other projects The Culture Our team is comprised of people with a variety of backgrounds: standard engineering degrees to philosophy degrees; big-tech background to scrappy startups. But we have at least one common skill: everyone on the team, including managers, is held to the same high standard of engineering competency. In addition, we value in-person work for its value in building trust and sharing knowledge and mentoring each other.
