Senior Full-Stack Engineer (AI-Native)

About Toku Every company in the world runs payroll. But the rails underneath it haven’t changed since the 1970s. Toku is building what comes next - infrastructure that makes payroll work the way the internet does: instantly, globally, and without unnecessary friction. ‍ We enable companies to pay teams in stablecoins, fiat, or tokens - without switching systems, retraining staff, or giving up compliance. With one API, Toku connects into platforms like ADP, Gusto, or Workday, and upgrades the back end to move money in seconds instead of days. We're building the future of payroll and we're just getting started. To learn more, check our website. We are hiring a Senior Full-Stack Engineer who is deeply AI-native. This is not a traditional coding role. Our engineering workflow is agent-first, and we expect engineers to use AI as their primary interface for design, implementation, testing, refactoring, and delivery. Toku builds mission-critical software across payroll, token administration, and financial operations. We ship fast, operate with high ownership, and expect excellent engineering judgment. If agents have not significantly transformed the way you work, this role is not a fit.
