TypeScript Developer Jobs
TypeScript has become the default language of modern web development. Almost every serious React, Node or Deno codebase written today uses TypeScript for its type safety, refactorability and developer experience. In Web3, TypeScript is the lingua franca of dApps — viem, wagmi, ethers, RainbowKit and the entire Ethereum tooling ecosystem are TypeScript-first.
Why TypeScript Won the Web
TypeScript combines JavaScript's ubiquity with a mature, powerful type system. Editors give real feedback, refactors are safe, and teams scale from three engineers to three hundred without the codebase falling apart.
Web3 leaned into TypeScript hard: viem and wagmi generate types straight from ABIs, so contract calls, event handlers and hooks are all fully typed. Any dApp of meaningful size is TypeScript.
Featured Jobs
What TypeScript Developers Do
TypeScript engineers build across the entire stack: frontends, APIs, edge functions and infrastructure.
- Build React and Next.js applications with strict TypeScript
- Design Node, Nest or Bun backends with typed API contracts
- Integrate with EVM chains using viem, wagmi and ethers.js
- Ship serverless and edge functions on Vercel, Cloudflare and AWS
- Model complex domains with discriminated unions, generics and Zod schemas
- Own end-to-end testing with Playwright and Vitest
Career Paths and Salaries
TypeScript is a baseline expectation for most modern web roles. Full-stack TypeScript engineers with Web3 experience are among the most in-demand hires in crypto.
- Junior TypeScript Developer: $60,000 – $95,000 per year
- Mid-Level Full-Stack Engineer: $95,000 – $150,000 per year
- Senior TypeScript Engineer: $150,000 – $220,000 per year
- TypeScript + Web3 Full-Stack Specialist: $170,000 – $280,000+ per year
- Freelance rates: $80 – $180+ per hour

Frequently Asked Questions
1. Is TypeScript replacing JavaScript?
In new codebases, essentially yes. JavaScript remains crucial to know, but TypeScript is the default for anything beyond a small script.
2. Do I need to know React to get a TypeScript job?
Not necessarily — Node, Nest and full-stack backend roles are plentiful — but React + TypeScript is the single most in-demand combination.
3. How strict should my TypeScript be?
Enable strict mode from day one. Modern teams expect it, and it pays back the effort within weeks.
4. Is TypeScript useful for smart contracts?
Smart contracts themselves are Solidity, but everything around them — deployment scripts, indexers, frontends, SDKs — is overwhelmingly TypeScript.
