Software Engineer, Tax

At Gusto, we're on a mission to grow the small business economy. We handle the hard stuff — payroll, health insurance, 401(k) s, and HR — so owners can focus on their craft and their customers. With teams in Denver, San Francisco, and New York, we support more than 500,000 small businesses nationwide and are building a workplace that reflects the people we serve.

All full-time employees receive competitive base pay, benefits, and equity (RSUs) — because everyone who helps build Gusto should share in its success. Offer amounts are determined by role, level, and location. Learn more about our Total Rewards philosophy.

AI is a fundamental part of how work gets done  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.

We’re a small group of talented engineers, designers, data scientists, and product managers working to improve the experience of collecting, calculating, paying, and filing taxes. Our team aims to make the complexity of dealing with hundreds of tax agencies disappear and to make compliance easy.

We own everything a customer sees and does around taxes: from onboarding through ongoing account management, payments, and filings. We make sure that communication about those experiences is clear and actionable, and that the underlying systems are reasonable and sustainable to build on.

This team is responsible for the full stack of work, not just the frontend. We implement work up and down the stack to build these delightful experiences, and we partner regularly with all of the teams in the Tax Organization and many teams outside of it as well.

This is one of the most important teams t companies know how to pay their people, but many companies don't know how to properly withhold, pay, or file taxes. One of the reasons that they pay for Gusto every month is the exact product that we provide.
