The opportunity

About Gusto 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 they're looking for

  • Successful applicants typically have 8+ years of software development experience
  • Hands-on experience taking AI/LLM capabilities to production: agent orchestration, tool integration, retrieval, and evaluation/feedback loops that keep AI improving safely
  • AI fluency: fluent, daily use of AI coding assistants (e.g., Claude Code, or: equivalent AI harness) across the development lifecycle — writing, reviewing, debugging, and documenting code — with strong judgment on when to apply them, how to evaluate output quality, and how to stay current as the tooling evolves
  • Passion for creating scalable, efficient platforms for users
