Senior Software Engineer, Agentic Systems

Are you looking to build tools that engineers actually keep in their workflow? Do you get excited about AI agents that fix real vulnerabilities instead of writing confident nonsense about them? Are you willing to tolerate ridiculous bird puns? If you said yes to at least two of those, keep reading.

StackHawk builds the security layer for AI-assisted engineering. Our platform finds exploitable vulnerabilities in running applications and APIs, then hands the proof and the fix path directly to the coding agent already sitting in the developer's editor. Claude Code, Cursor, Copilot, Codex. Scan, fix, verify, in a loop, without a human copying findings between tabs.

That product is real and shipping. It is also early, which means the architecture decisions that matter most have not been made yet.

We are looking for a senior engineer to own that loop. You will spend most of your time on agentic systems: the tool surfaces our agents call, the context they get, the loop that decides when a fix is actually verified, and the evals that tell us whether any of it got better this week. You will also work in the core platform, because the loop is only as good as the scan engine and APIs underneath it. This is not a research role. Everything you build goes to customers.
