Senior Software Engineer, Onboarding

The Onboarding teams transform a weeks-long, support-heavy onboarding process into a fully self-serve experience, leveraging AI-powered data ingestion and real-time validation to take companies from signed contract to running payroll in a matter of days. A core part of this work is unifying how people join Justworks - today, full-time, contractor, and international hires across PEO, ASO, and EOR each follow entirely different flows, and this role brings them all into one. Ultimately, this is about building the first product experience every new customer has. If onboarding feels hard, nothing else matters - making this role a direct driver of activation rate, time-to-first-payroll, and onboarding completion.
