Staff Software Engineer, Tax Accounts
About The Position
We're looking for a seasoned full-stack software engineer to join Tax Accounts — the team whose job is to make the complexity of dealing with hundreds of tax agencies disappear. We're the steward of every Gusto customer's employer and employee tax account data: the registrations, authorizations, rates, and setup that let us withhold, pay, and file correctly on their behalf. Get it right and businesses stay compliant without thinking about it; get it wrong and it costs them real money and trust. As a Staff Software Engineer on Tax Accounts, you'll operate across the full product lifecycle: clean frontend code, reliable backend APIs and data models against a genuinely complex compliance domain, and the automation that keeps hundreds of thousands of accounts in sync with the agencies behind them. If you want technical craft with far-reaching impact in our modern economy helping power the livelihoods of millions of small business employees — join us.
Requirements
- 8+ years of software development experience
- Experience owning multi-quarter projects that solve complex engineering problems and make measurable customer impact at scale
- Experience building scalable solutions that eliminate customer pain, and a strong sense of ownership over reliability, performance, and correctness
- Comfort designing data models and APIs for a complex, rules-heavy domain (compliance, tax, payments, or similar) where edge cases and correctness matter
- Experience leveraging AI tools or systems to accelerate development, improve testing, and deliver new capabilities — plus curiosity and experimentation with emerging AI frameworks, and a habit of sharing best practices to scale AI use safely across the team
- Ability to mentor engineers to maximize their performance and impact
- Ability to communicate effectively across engineering teams and with business stakeholders
Nice To Haves
- Experience in, or interest working in, Ruby on Rails
- Appreciation for a collaborative, test-driven environment
- Ability to build well-structured, maintainable, well-documented code
- Ability to effectively communicate across engineering teams and with business stakeholders
Responsibilities
- Design, build, and test the systems behind employer and employee tax accounts: agency registrations, power-of-attorney / third-party authorizations, tax notices, agency filings, and state/federal/employee tax setup across jurisdictions
- Build automation that requests and maintains access with tax agencies on the customer's behalf — the bots, data exchanges, and agency-event pipelines that keep accounts, rates, and deposit schedules accurate and prevent failed filings
- Model complex, jurisdiction-specific compliance rules into maintainable systems, and own reliability, performance, and correctness in a domain where accuracy is non-negotiable
- Partner closely with Product, Design, Tax Operations, and PEO teams to turn customer and compliance pain into solutions — then prototype, iterate, and launch
- Mentor other engineers and help the team solve some of the hardest problems in a very complex domain, at large scale
- Build products that our customers genuinely love
