Gusto's mission is to grow the small business economy by handling payroll, health insurance, 401(k)s, and HR for small businesses.

You'll join the Application Engineering team, which supports the platforms used to deliver Sales and CX interactions. The platforms have tremendous scale, and the work directly shapes how the rest of Gusto operates. The team challenges the status quo, advocates for scalable technical solutions, and holds a high bar for quality while translating ambiguous requirements into real business value.

• 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.

• 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.
• 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.

Cash compensation 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.
