Senior Full-Stack Engineer (AI-Native)

About this role

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.

If agents have not significantly transformed the way you work, this role is not a fit.


How We Build

• Daily use of Claude and Codex across the full SDLC
• Agent-first execution; we do not expect handwritten code as the default path

• Build and ship full-stack features across frontend and backend systems
• Own work end-to-end: product requirements, architecture, implementation, testing, rollout, and monitoring
• Use AI agents to accelerate delivery while improving reliability and maintainability
• Partner closely with product, design, and operations to deliver high-impact outcomes quickly
• Improve internal engineering workflows for AI-native deve...
