Senior Staff Software Engineer, Onboarding and ActivationNew

The opportunity

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.

What you'll do

  • Own meaningful slices of the signup-to-activation experience end to end: from data model to UI — and ship measurable improvements to how quickly and reliably new customers get up and running.

  • Invent and prototype net-new, 0-to-1 experiences: bringing your own ideas for how AI can reimagine onboarding, not just implementing a spec handed to you.

  • Partner directly with Product, Design, and Data to frame problems, form: hypotheses, and validate them with real customers in weeks, not quarters.

  • Identify where AI meaningfully removes customer effort (and where a simple: form is better), and build those experiences thoughtfully into the flow.

  • Design onboarding as modular, reusable building blocks so new entry points: into Gusto can be added quickly without rebuilding the foundation.

  • Raise the engineering bar through pragmatic technical direction, high-quality: code, strong reviews, and mentoring engineers around you.

What they're looking for

  • Make sharp scoping calls under a time box: shipping the simplest version that proves or disproves an idea, then iterating.
  • + years of software engineering experience, including building and shipping customer-facing products at scale.
  • A product-minded engineer who starts from the customer problem and the metric: that matters, not just the ticket — and who can operate independently across product, design, and data partners.
  • Demonstrated ability to move fast and execute with high quality: someone who ships, measures, and iterates rather than waiting for perfect certainty.
