Staff Software Engineer, Salesforce Developer

Gusto is on a mission to grow the small business economy, handling payroll, health insurance, 401(k)s, and HR for over 500,000 small businesses. We are building a workplace that reflects the people we serve.

Join the Application Engineering team, which supports the platforms used to deliver exceptional Sales and CX interactions. Our platforms have tremendous scale, and the work directly shapes how the rest of Gusto operates.

• 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.

• 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.

Please note that a two day travel to a Gusto office for onboarding is required for this position.
