Senior Staff Software Engineer, Integrated Benefits Platform at Gusto

**Who this is for** This role is designed for a seasoned architectural leader with over 10 years of experience, specifically within complex backend environments using Ruby on Rails. You should be someone who excels at navigating high-ambiguity spaces and designing scalable platform foundations that support multiple internal teams and external integrations. **Key highlights** The role offers a strong compensation package ranging from $223k to $265k plus equity. While based in San Francisco or New York, it features a hybrid model requiring only 2-3 days in the office per week. This is a high-visibility position where you will influence the long-term technical strategy as the platform transitions toward AI-native systems. **You might be a good fit if you...** * Have deep expertise in Ruby on Rails and evolving large-scale, service-oriented architectures. * Enjoy leading through influence rather than authority to align cross-functional teams on technical standards. * Are interested in applying AI tools to production engineering workflows to improve development velocity and system quality. * Have a background in highly regulated industries like Fintech, Payroll, or Health Benefits.
