Antithesis is an autonomous software testing platform that finds the bugs others miss. Backed by Amplify.
About the role
We're looking for Engineering Managers to add 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.
What they're looking for
- Strong engineering chops — comfortable in C++, Python, Java, Go, or similar. You don't need to know every language we use, but you do need to be genuinely good at programming
- Experience with test infrastructure, or developer tooling is a major plus
- Deep experience with distributed systems, databases, and large-scale architectures — ideally with some scars to prove it
- Proven track record of leading engineering teams — recruiting, mentoring, and growing talent, ideally in a startup or high-growth environment
- Strong technical judgment. You can make the right call on hard architectural questions and explain why clearly
- Excellent communicator. You can align engineers, PMs, and executives around a shared direction without losing anyone along the way
More about this role
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.
