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.

As a Gusto Software Engineer at this level, you’ll be guiding projects end-to-end by driving large technical architectural decisions (focusing on scale and modularity), understanding how to take existing systems closer to desired end states, executing on projects, and maintaining code that powers core experiences.
