Retirement Financial Infrastructure Senior Staff Engineer at Gusto

**Who this is for** This role is designed for a heavyweight backend expert with 10+ years of experience who thrives on building "high-correctness" systems. The ideal candidate has a deep background in financial infrastructure—specifically money movement, payments, and settlements—where precision is non-negotiable. You should be someone who enjoys staying hands-on with production code while navigating complex compliance and regulatory requirements. **Key highlights** The compensation is highly competitive, reaching up to $278,000 in major hubs like NYC and SF, plus stock equity. While the role is tied to Gusto’s offices in Denver, SF, or NYC, it offers a hybrid balance with 2-3 days in-office. This is a chance to exert senior-level influence over the core financial engine of a platform supporting 400,000+ businesses. **You might be a good fit if you...** * Have a decade of experience shipping robust production platforms. * Experience with Ruby on Rails or a similar backend framework in a data-heavy environment. * Are comfortable owning the entire lifecycle of a service, including debugging and operational support. * Value pragmatic engineering over theoretical perfection and can translate complex financial logic into clean APIs.
