TypeScript developers
Rates, hiring difficulty, a hiring guide and interview questions for a TypeScript developer: everything in one place.
Overview
TypeScript developers build type-safe applications across the full stack — frontend with React/Vue/Angular, backend with Node.js/Deno/Bun, and everything in between. TypeScript has become the default for professional JavaScript development, adding compile-time safety that catches bugs before they hit production.
Hiring TypeScript developers is competitive. The talent pool is large but so is demand, so senior people get snapped up quickly.
Where to find more talent: Node.js developers (20% want to move into TypeScript).
Retention: 55% of developers who use TypeScript want to keep using it, and 12% of those who do not use it yet want to start.

What a TypeScript developer costs
Contract and salary benchmarks for the US.
Contract rate
C2C or 1099, from W-2 hourly × 1.3–1.6 for tax, benefits and overhead.
W-2 equivalent
BLS median for US software developers ($135,980), adjusted +3% for TypeScript using Stack Overflow 2025 pay data (1,878 respondents).
Full-time contractor cost
Per year at 40 hours a week.
Agencies typically bill 2–3× W-2 pay. See what a full project costs, compare W-2, 1099 and C2C, or check rates by state.
How to hire a TypeScript developer
What good looks like, and what should worry you.
Typical projects
- Full-stack web applications with shared types between frontend and backend
- Node.js API services with Express, Fastify, or tRPC
- Large-scale frontend applications where type safety prevents bugs
- SDK and library development for other developers
- Migration of JavaScript codebases to TypeScript
Team setup
TypeScript developers are the most versatile hires for web-heavy teams. A strong TypeScript developer can work on both your React frontend and Node.js backend, reducing the communication overhead of separate frontend/backend teams. For larger projects, consider hiring TypeScript developers who specialize in either frontend or backend, as depth still matters.
What to look for
- Goes beyond basic types — understands generics, conditional types, mapped types, and template literals
- Can configure tsconfig.json properly and explain strict mode settings
- Experience with type-safe API patterns (tRPC, Zod, or similar schema validation)
- Understands the TypeScript compiler and knows when to use type assertions vs type guards
- Can write types that help teammates, not types that impress on Twitter
Red flags
- Uses 'any' liberally — defeats the entire purpose of TypeScript
- Can't explain the difference between 'type' and 'interface' and when to use each
- No understanding of generics — they're fundamental to real-world TypeScript
- Writes overly complex types that are impossible for the team to understand or maintain
- Treats TypeScript as 'JavaScript with annotations' rather than understanding the type system
Interview questions
Questions that separate strong candidates from people who just list the keyword.
- Write a generic function that takes an array of objects and a key, and returns an array of values for that key — with full type safety.
- How do you handle API response types when the backend isn't in TypeScript?
- What's your approach to organizing types in a large codebase? Colocated vs centralized?
- Explain discriminated unions and give me a real-world example where you'd use them.
- How do you balance type strictness with developer productivity? Where do you draw the line?
Hiring trend
How often TypeScript appears in startup hiring posts over time.
Hacker News “Who’s Hiring” posts mentioning TypeScript, by year (2015–Feb 2025). Peak: 2020 with 286 posts. HN hiring overall has fallen since 2019, so compare stacks rather than reading absolute numbers. Its share of current US job postings changed +10% since April 2026.

Questions
How much does a TypeScript developer cost?
Contract TypeScript developers typically bill $88–108/hr (C2C or 1099). The W-2 equivalent salary is about $140,300. Agencies usually charge 2–3× W-2 pay.
Is it hard to hire TypeScript developers?
TypeScript is rated High on our hiring difficulty index (62/100, #13 of 29), with about 18 open US roles for every 1,000 developers who use it.
Should I hire a full-time TypeScript developer or use a contractor?
If the work is ongoing and core to your product, hire. If you need to start quickly, cover a gap, or the role is hard to fill, a contractor or agency gets work moving while you search.
