• We’re looking for seasoned full-stack software engineers to join the teams behind Gusto’s product platforms — the shared systems that our product teams build upon — to serve small business owners every day
• As a Staff Software Engineer, you’ll operate across the full lifecycle of foundational systems: shaping architecture early in the design process, building self-service internal features and APIs, and owning their performance long after launch
• That means engineering the core business engine, enabling product teams with reliable backend services, and setting the engineering standard for those around you
• Design, build, and test Gusto core platform services – communications, reporting, dashboards, access, workflows, risk, payments, and compliance capabilities, among others
• 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 Engineering, Product Management, Data, and Design teams to understand customer pain points, come up with solutions, and then prototype, iterate, and launch daily
• Build platforms that engineering teams rely on, and trust to deliver products that our customers genuinely love
