Lead end-to-end full-stack feature development using AI agents across frontend and backend: own requirements, architecture, implementation, testing, rollout, and monitoring while improving AI-native engineering workflows and reliability.
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.

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.
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.
- No token budget constraints for engineering workflows.
- Strong emphasis on throughput, correctness, and review quality with AI-assisted development.
What You’ll Do
- 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 development and team leverage.
What We’re Looking For
- 5 to 7+ years of software engineering experience in production environments.
- Strong full-stack skills (TypeScript/JavaScript, modern frontend frameworks, backend APIs, SQL/data modeling).
- Clear track record of shipping customer-facing features and backend systems.
- Heavy, practical, and proven daily use of AI coding agents.
- Excellent prompt-to-production workflow: spec → agent loops → validation → deploy.
- Strong testing discipline and ability to reason about failure modes.
Non-Negotiables
- You are a rampant user of AI tools for engineering work.
- You are comfortable in an agent-first environment where handwritten code is not the default.
- You believe AI agents have fundamentally changed how high-performing engineers work.
Nice to Have
- Experience in fintech, payroll, payments, or crypto-enabled systems.
- Experience with Next.js, Node.js, Prisma, and typed API patterns.
- Experience improving developer productivity systems and AI-enabled engineering standards.
Toku is an equal opportunity employer, and we are committed to being a diverse team that reflects a broad range of background, thought, and experience. We do not discriminate based on race, color, religion, sex, gender identity, sexual orientation, age, national origin, status as an individual with a disability, status as protected veteran, or any other legally protected characteristics. Women, minorities, LGBTQ+, and people from underrepresented backgrounds are strongly encouraged to apply.
