Staff Software Engineer, PEO BenefitsActive$197K–$247K

The opportunity

At Gusto, we're on a mission to grow the small business economy. We handle the hard stuff — payroll, health insurance, 401(k)s, and HR — so owners can focus on their craft and their customers.

What you'll do

  • Design, build, and test the Gusto PEO Benefits experience: the benefits shopping and plan-recommendation flows, carrier integrations, MCP tools, agents that automate operational and customer support processes

  • 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 Management, Data, Design, and Platform: Engineering teams to understand customer pain points, come up with solutions, and then prototype, iterate, and launch daily

  • Build products that our customers genuinely love

  • Successful applicants typically have 8+ years of software development experience

What they're looking for

  • PEO Expertise (Preferred): 3+ years of experience with PEO, with direct experience building PEO flows in a high-growth environment.
  • Experience owning multi-quarter projects that solve complex engineering: problems and make measurable customer impact at scale
  • Experience driving large, cross-functional projects end-to-end through: ambiguity — scoping, sequencing, and unblocking without needing the problem pre-broken-down; aligning multiple stakeholders and working with multiple teams
  • Experience leveraging AI tools or systems to accelerate development, improve: testing, and deliver new product capabilities
