Role Overview
The Platform team is the engine room of Antithesis — we own the infrastructure, services, and tools that are at the core of the product. As a Senior Backend Engineer here, you won't be maintaining someone else's abstractions. You'll be designing them from scratch, owning them end-to-end, across the full stack: from raw binary formats and block compaction all the way up to the external APIs our customers depend on. Correctness and performance aren't nice-to-haves here — they're the job.
If you get unreasonably excited about systems design, performance, storage efficiency, clean API contracts, and finding the bottleneck nobody else noticed, we'd love to talk.

About Antithesis
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.
