Senior Full-Stack Engineer (AI-Native)

** About Toku**

Every company in the world runs payroll, but traditional payroll infrastructure has remained stagnant since the 1970s. Toku is leading the way in revolutionizing payroll by implementing cutting-edge technology that enables instant, global, and seamless payroll processes without unnecessary complexities.

Toku allows businesses to pay their teams in stablecoins, fiat, or tokens without the need to switch systems, retrain staff, or compromise on compliance.
