Skills Checklist: What to Look For When You Hire TypeScript Developers

If you are scaling your frontend or backend systems and considering TypeScript, you are not alone. TypeScript is rapidly becoming the industry standard among tech companies for developing scalable, maintainable, and safer codebases. But knowing the language isn’t enough. Not every developer who claims to “know TypeScript” can handle real-world product requirements, collaborate with cross-functional teams, or write code that lasts through multiple product iterations.

So how do you ensure you are hiring the right fit for your team? It starts with knowing what really matters—beyond the resume. This blog breaks down a practical, skill-driven checklist to guide you before you hire TypeScript developers. Whether you are building an internal tool, a client-facing product, or a complex multi-service platform, these pointers can save your hiring process from expensive misfires.

Why Technical Depth and Real-World Problem Solving Matter More Than Just Syntax Mastery

1. Deep Understanding of TypeScript Fundamentals (Not Just JavaScript)

A common trap in hiring is assuming that any JavaScript developer can just “pick up TypeScript.” While it’s true that TypeScript builds on JavaScript, the way developers structure code, handle types, and design interfaces in TypeScript is fundamentally different.

When you hire TypeScript developers, look for candidates who can:

Explain the difference between interfaces and types.
Use advanced features like mapped types, generics, and utility types.
Show how static typing reduces bugs and improves documentation.
Demonstrate clean error handling with discriminated unions.

A strong grasp of TypeScript leads to fewer bugs, more predictable code, and stronger tooling support. If your candidate leans on “any” type too often, that’s a red flag.

2. Experience with Modern Frontend Frameworks Using TypeScript

It’s not enough for developers to just write good code in isolation. Most tech companies use frameworks like React, Angular, or Vue with TypeScript. Your ideal hire should already have production experience integrating TypeScript into these ecosystems.

Ask candidates:

Have you used TypeScript in a Next.js or Angular app?
Can you set up a typed Redux store?
How do you handle component props and state with TypeScript?
Do you know how to create reusable and typed UI components?

Developers who have already shipped real apps with TypeScript are more likely to foresee issues and write scalable front-end architecture.

3. Backend Development or Full-Stack Knowledge

TypeScript isn’t just for front-end development. Frameworks like Node.js (via NestJS or Express) are increasingly adopting TypeScript. If your project involves server-side logic, APIs, or database handling, a TypeScript developer with full-stack awareness is a significant asset.

A well-rounded candidate should be able to:

Set up type-safe REST APIs or GraphQL endpoints.
Manage environment configurations using types.
Use ORMs like Prisma or TypeORM with TypeScript.
Write clean and testable service logic.

This combination of frontend and backend skill makes them more valuable in lean teams or fast-paced startup environments.

4. Strong Testing Practices with TypeScript

Unit tests, integration tests, and end-to-end tests are essential for robust applications. TypeScript offers built-in safeguards, but testing adds an additional layer of protection.

Great TypeScript developers:

Use frameworks like Jest, Mocha, or Vitest in TypeScript.
Write meaningful unit tests that are type-safe.
Understand testing tools like Cypress for front-end and Supertest for backend.
Use mocks and stubs with strict typing.

Tech companies that focus on long-term product quality understand the importance of strong testing culture, especially when building complex systems.

5. Communication and Collaboration Skills

Technical ability is just half of the equation. In collaborative environments, especially in remote teams or fast-paced startups, communication makes or breaks productivity.

When you hire TypeScript developers, assess:

Can they explain technical decisions clearly?
Do they ask questions when requirements are vague?
Are they able to work well with product managers and designers?
How do they handle code reviews and feedback?

Great communication avoids misunderstandings, ensures faster delivery, and results in cleaner implementations. This is where many technically skilled candidates fall short—and where true professionals shine.

Another important consideration is flexibility across team structures. Whether you are a startup scaling up or an enterprise modernizing legacy apps, it helps to hire TypeScript engineers who can seamlessly integrate into diverse environments—from agile squads to cross-functional pods.

6. Familiarity with Build Tools and DevOps Basics

TypeScript developers who can independently set up builds, understand CI/CD pipelines, and troubleshoot basic deployment issues are far more self-sufficient.

Look for developers who:

Know how to configure Webpack or Vite with TypeScript.
Use ESLint, Prettier, and tsconfig for consistent code quality.
Can write scripts for builds or pre-deployment validation.
Understand Docker, GitHub Actions, or other pipeline tools.

This independence frees up your DevOps or infra teams and speeds up iteration cycles.

7. Version Control, Code Reviews, and Git Workflow Mastery

Tech companies increasingly value candidates who not only write code but contribute meaningfully to collaborative processes. Mastery of Git isn’t just a bonus—it’s essential.

Check if your candidate:

Knows how to create and manage branches for feature work.
Can resolve merge conflicts responsibly.
Has experience in structured pull request workflows.
Participates in meaningful code reviews and gives thoughtful feedback.

In distributed teams, clear and consistent version control usage is key to productivity. Some hiring managers also look for portfolios that showcase versatility. If your project is long-term and you need design-consistent outputs, consider browsing for typescript developers for hire who have worked with design systems, Storybook, or component libraries.

8. Culture Fit and Adaptability in Fast-Moving Tech Companies

Finally, soft skills still matter. Startups, SaaS companies, and product-led tech teams often pivot quickly based on market feedback. You will want a developer who embraces that pace.

When you hire TypeScript developers, ask:

How do you handle changing requirements or shifting priorities?
Can you adapt quickly to new tools or stack changes?
Are you comfortable contributing outside your job description?

Adaptability helps developers succeed not just in your current project, but in future initiatives where team structures and goals evolve.

Conclusion: Hire for Long-Term Impact, Not Just Short-Term Code

Hiring TypeScript developers shouldn’t just be about who can write the cleanest code—it’s about finding someone who can grow with your product, reduce technical debt, and communicate clearly with your entire team. Whether you are a bootstrapped startup or a growing SaaS brand, these skills are crucial.

Take time to go beyond coding challenges and resumes. Ask in-depth questions. Review GitHub profiles. Run real-world scenarios. The developer who checks most (if not all) of these boxes will be an investment in your product’s long-term stability and speed.

If you want to avoid the overhead of vetting multiple candidates, it might help to look into platforms where you can hire TypeScript developers who are already screened for technical depth, problem-solving, and communication skills.
