Staff Software Engineer - Payroll Platform at Gusto

**Who this is for** This role is designed for a seasoned backend expert with over 8 years of experience who enjoys building foundational infrastructure. You should have a track record of designing internal APIs and platforms that other engineering teams rely on. While Ruby is the preferred language, the team is open to polyglot engineers with strong systems design skills and a background in scaling high-reliability services. **Key highlights** The compensation is highly competitive, ranging from $163k to $247k depending on your location, plus equity. This is a hybrid role (2-3 days in-office) in major hubs like Denver, SF, NYC, or Seattle. A unique aspect of this position is the explicit focus on AI-assisted development; you’ll be expected to use and champion tools like LLMs and Cursor to accelerate the team’s output. **You might be a good fit if you...** * Have extensive experience building backend product infrastructure and shared services. * Enjoy untangling complex business logic (like payroll and compliance) into clean, scalable APIs. * Are comfortable working in a highly regulated domain where accuracy and data integrity are non-negotiable. * Already integrate AI coding tools into your daily workflow to improve code quality and speed.
