Job description

About the company

At the company, 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 the company 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 at the company. 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.

We're looking for seasoned full-stack software engineers to join the company's HR Experience team.

Half the American workforce works at a small business, and most of those businesses can't afford a real HR team. When they hit an HR decision they don't have the expertise for — a termination, a comp change, setting a time-off policy for the first time — they either pay for expensive outside help or guess, even though the right answer depends on rules that vary across 50 states and hundreds of localities. HR Experience is building that expertise directly into the company: compliant HR guidance and documentation, built natively for both the employer creating it and the employee receiving it, in a domain where the compliance bar is real — \"mostly right\" isn't good enough.

You’ll also help drive the other half of HR Experience's mission: using AI to make the company's human HR Partners faster and more effective, so more small businesses can get real HR support without needing to hire their own HR team.

As a Staff Software Engineer, you'll operate across the full product lifecycle: shaping features from early spec and design through to launch and long-term iteration. That means writing clean frontend code, designing and building reliable backend APIs, influencing product direction, and taking ownership of what happens after a feature ships.

If you're drawn to work that combines technical craft with real-world impact — helping small businesses get HR infrastructure they can actually rely on — join us!

Here’s what you’ll do day-to-day:

• Design, build, and test across the company's HR experience — the employer-facing document and guidance tools, and the employee-facing side of that same experience

• Build AI tools and agents that help scale the company's HR Partners team, automating the compliance and document workflows human HR partners handle today

• Mentor other engineers to help solve some of the hardest technical problems out there in very complex domains and at a large scale

• Help scale one of the largest Ruby/Rails and Javascript/React applications in the world

• Collaborate with our Product Management, Data, Design, and Platform Engineering teams to understand customer pain points, come up with solutions, and then prototype, iterate, and launch

• Build products that our customers genuinely love

Here’s what we’re looking for:

• Successful applicants typically have 8+ years of software development experience

• Compliance/HR Domain Expertise (Preferred): experience building products in regulated, compliance-heavy domains (HR, payroll, benefits, tax, or similar), especially where requirements vary by state or locality

• Experience owning multi-quarter projects that solve complex engineering problems and make measurable customer impact at scale

• Experience driving large, cross-functional projects end-to-end through ambiguity — scoping, sequencing, and unblocking without needing the problem pre-broken-down; aligning multiple stakeholders and working with multiple teams

• Actively uses agentic coding tools (for example, Claude Code or Codex) as part of your daily engineering workflow, and has used them to meaningfully accelerate yourself and others

• Experience with, or strong interest in, building agents and MCP tools — and judgment about applying them safely in domains where \"mostly right\" isn't good enough

• Ability to mentor engineers to maximize their performance and impact

Others:

• 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

Please note that travel to the company's office for onboarding is required for this position. If you have any questions regarding this requirement, please share with your recruiter.

Our cash compensation range for this role is $199,000–$247,000 for San Francisco & New York. Stock equity is additional. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amounts listed above.

Employees who are based in those locations will be expected to work from the office on designated days approximately 2-3 days per week (or more depending on role).

When approved to work from a location other than a the company office, a secure, reliable, and consistent internet connection is required. This includes non-office days for hybrid employees.
