Staff Software Engineer, HR Experiences

At Gusto, we're on a mission to grow the small business economy.

We're looking for a seasoned full-stack software engineer to join Gusto's HR Experience team, which provides compliant HR guidance and documentation to small businesses.

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.

Here's what you'll do day-to-day:

• Design, build, and test across Gusto's HR experience , the employer-facing document and guidance tools, and the employee-facing side of that same experience
• Build AI tools and agents that help scale Gusto's HR Partners team, automating the compliance and document workflows human HR partners handle today
• 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
• Build products that our customers genuinely love

We're looking for:

• Successful applicants typically have 8+ years of software development experience
• Compliance/HR Domain Expertise (Preferred): experience building products in regulated, compliance-heavy domains (HR, payroll, benefits, tax, or similar), especially where requirements vary by state or locality
• 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
• Actively uses agentic coding tools (for example, Claude Code or Codex) as part of your daily engineering workflow, and has used them to meaningfully accelerate yourself and others
• Experience with, or strong interest in, building agents and MCP tools , and judgment about applying them safely in domains where "mostly right" isn't good enough
• Ability to mentor engineers to maximize their performance and impact

Our cash compensation range for this role is $199,000–$247,000. Stock equity is additional. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amounts listed above.
