AI is a fundamental part of how work gets done at Gusto. We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process.
About the Role:
We're looking for seasoned full-stack software engineers to join the teams behind Gusto's product platforms — the shared systems that our product teams build upon — to serve small business owners every day.
As a Staff Software Engineer, you'll operate across the full lifecycle of foundational systems: shaping architecture early in the design process, building self-service internal features and APIs, and owning their performance long after launch. That means engineering the core business engine, enabling product teams with reliable backend services, and setting the engineering standard for those around you.
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 Gusto core platform services – communications, reporting, dashboards, access, workflows, risk, payments, and compliance capabilities, among others
- Mentor other engineers to help solve some of the hardest technical problems out there in very complex domains and at a large scale
- Help scale one of the largest Ruby/Rails and Javascript/React applications in the world
- Collaborate with our Product Engineering, Product Management, Data, and Design teams to understand customer pain points, come up with solutions, and then
