Senior Staff Engineer, Tax Platform Engineering
거스토 (Gusto)
You own the platform that calculates, pays and files payroll taxes for more than 500,000 US small businesses. The job scales one of the largest Ruby on Rails and TypeScript React codebases anywhere while building guardrails so agentic AI can touch tax concepts without compromising accuracy or compliance. You set the technical strategy and roadmap for your domain and lead legacy overhauls across several teams, which is why the posting asks for ten-plus years; base pay is $223,000 to $278,000 in San Francisco with equity on top.
Why this role fits
Payroll tax is a domain where a mistake turns into a penalty right away, so accuracy comes before speed. It suits someone who likes systems where change is deliberate and the blast radius is wide, and who has run large Rails and React services for years. Payroll, tax or compliance experience is preferred, not required.
