Staff Software Engineer, Salesforce Developer

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. With teams in Denver, San Francisco, and New York, we support more than 500,000 small businesses nationwide and are building a workplace that reflects the people we serve.

All full-time employees receive competitive base pay, benefits, and equity (RSUs) — because everyone who helps build Gusto should share in its success. Offer amounts are determined by role, level, and location. Learn more about our Total Rewards philosophy.

AI is a fundamental part of how work gets done at Gusto. We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process.

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.
