Engineering Manager

We've been quietly reinventing how the world thinks about software reliability, and we're just getting started! At Antithesis, we start at the foundations – we run entire software systems inside a deterministic simulation and break them in every way imaginable. Every issue then comes with a perfect reproduction, so you can identify root causes fast instead of spending days trying to recreate what went wrong.

The rise of AI-generated code has made this work more urgent than ever. Agents can write code faster than any human, but speed doesn't matter much when the output is buggy, stuck in review, or slipping through undetected. The verification bottleneck is real, it's growing, and solving it is one of the most consequential problems in software right now. That's what you'd be working on.

We're well-funded and deeply technical, the kind of place where the hardest problems get the most attention and the best ideas win regardless of who has them. If you want to do work that actually moves the needle on how reliable software can be, keep reading.

We're looking for Engineering Managers to our growing core engineering team. This isn't a "manage the roadmap and attend standups" kind of role — you'll be in the code, shaping architecture, and doing hard technical work alongside your team. You'll set direction, grow engineers, drive execution, and keep the bar high. We’re looking for first-line managers who are ready to lead from the front.

The team you'll lead depends on fit. Each area is different in flavor, but the expectations for the EM role are consistent: technical depth, strong people instincts, and the ability to move fast without breaking the things that matter.
