Senior Staff Engineer, Expansion ExperiencesActive$225K–$275K

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 outcomes across the full expansion funnel, not just a single surface or feature within it.

  • Shape the technical approach and architecture behind recommendations and: conversion journeys so it holds up as a foundation other initiatives can build on.

  • Make sharp scoping calls under a time box: ship the simplest version that proves or disproves an idea, then iterate based on what you learn.

  • Design experiments and use ambiguous or noisy data to decide what's worth scaling versus cutting.

  • Partner independently with Product, Design, and Data Science to help shape the roadmap, not just execute it.

  • Raise the engineering bar through pragmatic technical direction, strong code: review, and mentoring engineers around you, scoping out work and delegating it to other engineers on the team once it's ready to hand off.

What they're looking for

  • Successful applicants typically have 10+ years of software development: experience, including building and shipping full-stack, 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 can operate independently across product, design, and data partners.
  • Experience in a growth, lifecycle, or conversion-focused context (onboarding,: upsell flows, personalization, or recommendations) is ideal — or a demonstrated ability to think this way even without the exact domain background.
  • Demonstrated ability to move quickly and execute with high quality: someone who ships, measures, and iterates rather than waiting for perfect certainty.
