About
the Role: We're looking for seasoned full-stack software engineers to join Gusto’s PEO
Benefits team. Gusto is standing up a Professional Employer Organization (PEO) — one of the biggest new bets in the company — and
Benefits is the anchor of the offering. At the core is a national Master Health Plan that can unlock ~20–25% lower healthcare costs for small businesses through pooled purchasing power, something most PEOs can't pull off in year one. You'd be joining the engineering team building the systems that make that real. This is rare greenfield scope inside a company with real scale and real customers. You get to make foundational architectural decisions, not maintain someone else's. As a Staff Software Engineer, you'll operate across the full product lifecycle: shaping features from early spec and design through to launch and long-term iteration. That means writing clean frontend code, designing and building reliable backend APIs, influencing product direction, and taking ownership of what happens after a feature ships. If you're drawn to work that combines technical craft with real-world impact — helping power the livelihoods of millions using Gusto products — join us! Here’s what you’ll do day-to-day: Design, build, and test the Gusto PEO
