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.

Engineering Team - Who We Are
We’re an early, fast‑moving team that ships with care. We work closely with customers, value pragmatic engineering, clear documentation and keep reliability, correctness and security front and center.
The Role
You’ll own the core product areas end‑to‑end: from scoping, technical design to build, launch, and iteration. You’ll collaborate with operations and product teams on decisions and ship things balancing speed with sound engineering. If you want broad ownership and immediate user impact, you’ll fit right in.
What You’ll Do
- Ship user‑facing features across the stack with short feedback loops.
- Turn customer problems into simple and clear product solutions.
- Write robust, type‑safe, well‑tested code and stable APIs, keep docs and observability healthy.
- Raise the bar on engineering practices: PR reviews, automated testing, and robust CI/CD.
- Proactively identify opportunities to improve existing practices and uphold Toku’s high technical quality bar
- Anticipate edge cases, flag blockers early in the process, drive incidents to root cause, and prevent regressions.
- Lead feature work from PRD, design doc (RFC) to rollout: data models, API contracts, and UI flows.
- Use AI tools to accelerate development, testing, and documentation.
Requirements
- 3+ years building and operating production web apps end-to-end.
- Strong proficiency in TypeScript and JavaScript.
- Frontend knowledge: React or Next.js, performance, accessibility and testing fundamentals.
- Backend knowledge: Node.js with Express (or similar), Next js API routes, REST, JWT/OAuth, webhooks, background jobs.
- Database: Postgres (or other SQL based DBs), schema design, transactions, migrations, and basic performance tuning.
- DevEx and Infra: Knowledge of Git/GitHub, CI/CD, Docker; environment/secrets hygiene.
- Observability: Experience with popular observability tools (for eg. LogRocket, New Relic, Sentry)
- Good problem solving and communication skills
- Ability to pick up unfamiliar tech fast and execute if required in some scenarios
- Product mindset: clarify ambiguity quickly and slice scope to deliver outcomes.
- Code quality: clear abstractions, type safety, tests.
- Ownership: you like taking work from 0→1→10 and closing the loop with users.
- Hands‑on with AI‑assisted development (for eg. Copilot, Cursor, Devin). Experience with Cursor is a plus, we use it as a team and are open to adopting new tools.
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.
We strongly encourage you use Rezi.ai to vet resume quality before applying.

What does a React developer in web3 do?
A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain
These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network
Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain
As a React developer in web3, some of your responsibilities might include:
- Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
- Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
- Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
- Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
