Hire vetted TypeScript developers

TypeScript hiring divides neatly into two groups: people who add annotations until the errors stop, and people who use the type system to make invalid states impossible. Only the second group is worth the premium. The skill is not knowing syntax, it is knowing how much typing is enough. Over-engineered generics are as damaging as `any` scattered through a codebase, because both make the code harder to change. Strong TypeScript developers can explain when a union beats an enum, why they reached for a discriminated union, and where they deliberately stopped adding types because the cost exceeded the benefit. Since most teams adopt TypeScript on top of existing JavaScript, migration experience matters too: incremental adoption is a genuinely different problem from starting strict on day one.

What TypeScript developers do

• Design type models that make invalid application states unrepresentable
• Migrate JavaScript codebases to TypeScript incrementally without halting delivery
• Maintain shared types across front end, back end, and API boundaries
• Configure compiler strictness, build tooling, and type-level testing
• Write and maintain library type definitions consumed by other teams

TypeScript by the numbers

• TypeScript is used by 43.6% of professional developers and continues to grow as the default for new JavaScript projects. According to the Stack Overflow Developer Survey 2025 (2025).

What to expect at each level

What moves the rate

Seniority

The single biggest factor. Years of TypeScript work and the scope someone can own without supervision.

Timezone

Full overlap with your working day costs more than partial overlap.

Specialism

Niche TypeScript depth, performance work, and scarce adjacent skills carry a premium.

Commitment

Full-time engagements lower the hourly rate; short part-time work raises it.

Hiring dedicated TypeScript developers

Every RocketDevs developer works full time on one client. No time splitting across three other projects, no agency bench, and the same person every day. That is the default, not an upgrade.

Hiring offshore TypeScript developers

Our developers work from Africa, the Middle East, and South Asia, with 100% overlap with European hours and 6 to 8 hours with the US East Coast. Rates start at $9.99 per hour because our cost base is lower, not because the standard is.

Hiring remote TypeScript developers

Every engagement is remote by default and comes with the tracking to make that comfortable: real time logs, screenshots every 3 minutes, and the full assessment record before you commit.

Hiring senior TypeScript developers

Senior TypeScript developers cost $30.99 per hour, below the starting rate of most agencies and premium networks. You see the assessment scores before the interview, so seniority is evidenced rather than claimed.
