Gusto is seeking a Staff Software Engineer to own full-stack features independently for the HR Experience (HRX) product. You will design, build, and maintain features spanning frontend, backend, and data layers with minimal oversight, write clean and well-tested code, participate in code reviews and sprint planning, and partner with product and design teams to translate requirements into technical solutions. You'll help monitor and improve reliability, performance, and quality of shipped features, participate in on-call rotation and lead incident response for owned systems, and provide technical guidance and code-review mentorship to less-tenured engineers.
Gusto handles payroll, health insurance, 401(k)s, and HR for over 500,000 small businesses nationwide. The company has offices in Denver, San Francisco, and New York, with hybrid expectations of 2-3 days per week in office for NYC-based employees. All full-time employees receive competitive base pay, benefits, and equity (RSUs). AI fluency is expected as a fundamental part of how work gets done at Gusto.
REQUIREMENTS:
• 8+ years of professional software engineering experience, including full-stack work
• Demonstrated ability to design, build, and ship features spanning frontend, backend, and data layer with minimal oversight
• Strong proficiency in at least one modern backend language/framework (e.g., Ruby on Rails, Node.js, Python/Django) and one modern frontend framework (e.g., React, TypeScript)
• Solid understanding of relational databases — schema design, migrations, and query performance
• Comfortable owning a project end-to-end: scoping, technical design, implementation, testing, deployment, and monitoring
• Strong grounding in software engineering fundamentals: data structures, algorithms, automated testing, CI/CD
• Experience partnering cross-functionally with product managers, designers, and other engineers
• Clear written and verbal communication, including technical design docs

• Experience designing REST or GraphQL APIs
