About Gusto

About the Team:

You'll join the Application Engineering team, which supports the platforms we use to deliver exceptional Sales and CX interactions. Our platforms have tremendous scale, and the work we do here directly shapes how the rest of Gusto operates. We challenge the status quo, advocate for scalable technical solutions, and hold a high bar for what "great" looks like - while staying grounded in translating ambiguous requirements into real business value.

Here’s what you’ll do day-to-day:

  • Design, build, and maintain scalable Apex solutions on the Salesforce platform that support our Sales and CX teams
  • Use AI coding assistants (e.g., Claude Code or equivalent) throughout the development lifecycle to write, review, debug, and document code
  • Oversee ongoing improvements to deployed features and measure their impact
  • Apply Salesforce platform architecture and change/release management best practices, using sf cli for deployments
  • Write well-structured, easily maintainable, and well-documented code
  • Build, test, and debug reliable production systems at scale, ideally real-time, event-driven, or high-throughput
  • Contribute to codebases beyond Salesforce when the work calls for it

Here’s what we're looking for:

  • 6+ years of professional software engineering experience, including 4+ years developing on the Salesforce platform in Apex
  • Salesforce Platform Developer I and/or Application Architect certification(s)
  • Strong understanding of Salesforce platform architecture, with experience using the sf CLI and Salesforce change/release management best practices
  • Fluent, daily use of AI coding assistants (e.g., Claude Code or equivalent) across the development lifecycle — writing, reviewing, debugging, and documenting code — with strong judgment on when and how to apply them
  • Comfortable writing well-structured, maintainable, well-documented code, including in codebases outside of Salesforce (Ruby on Rails experience a plus)
  • Proven track record building, testing, and debugging reliable production systems at scale
  • Skilled at translating ambiguous requirements into business value and advocating for scalable technical solutions
  • Experience in regulated industries preferred

Please note that a two day travel to a Gusto office for onboarding is required for this position. If you have any questions regarding this requirement, please share with your recruiter.

Our cash compensation amount for this role is targeted at $163,000–$204,000 in Denver & most remote locations, and $197,000–$247,000 for San Francisco & New York. 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.
