Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Strong match if you like ownership of high-stakes first-run experiences at an SMB-focused platform in NYC. Less fit if you want remote-only work or pure greenfield research without production ops.
As Senior Software Engineer, Onboarding at Justworks, you would likely own services and UI that take new customers and employees from signup through first successful payroll or benefits setup. Expect design reviews, shipping reliability fixes on critical paths, partnering with product/design/support on drop-off, and mentoring on the onboarding stack.
Strengthen full-stack delivery for multi-step flows: API design, state machines, observability, and A/B-friendly UI. Domain depth in payroll/HR compliance and secure handling of sensitive data is useful. With no listed cert track, prioritize production ownership and system design over credentials.
No. The listing is New York City–based with remote set to off-site only (remote flag 0).
Engineering for the product path that gets companies and people set up on Justworks—not HR employee onboarding for your own hire.
