React​/TypeScript Developer

At Sqills we’re looking for someone with a strong focus on architecture, abstraction, and developer experience.

Unlike typical front-end roles focused mainly on converting Figma designs into components, this position centers on building and maintaining a reusable React/Type Script component library at the core of our design system.

You’ll work closely with our UX and UI designers to translate the design language into robust, reusable abstractions that are both scalable and maintainable. Your goal is to make the library consistent, intuitive, and enjoyable for developers to use across applications.

Collaboration with Dev Ops and engineering teams will be a key part of your role, ensuring that components integrate smoothly into applications. Ultimately, your work will directly shape the developer experience (DX) — making the system seamless, efficient, and future-proof.

What will you do:

• Develop and maintain a React/Type Script library used across our applications.

• Design and implement clean abstractions and APIs for components.

• Ensure the library is easy to use, consistent, and well-documented.

• Collaborate with designers to integrate the library in a way that balances flexibility and structure.

• Drive best practices in component architecture, code quality, and testing.

• Improve developer experience (DX) for consumers of the library.

  We are looking for someone with:

  • Bachelor’s degree (HBO or WO) in Computer Science, Software Engineering, or a related field — or equivalent professional experience.

  • Strong proficiency in React and Type Script.

  • Solid understanding of component architecture, code structure, and abstraction.

  • Experience building and maintaining design systems or reusable component libraries.

  • Ability to think in terms of developer experience

  • Comfortable collaborating with designers and bridging design with engineering.

    Nice to have:

    • Experience with MUI.

    • Familiarity with Vite, or similar bundling workflows.

    • Knowledge of CSS-in-JS, utility-first frameworks, or styling methodologies.

    • Open-source contributions or experience with widely used component libraries.

    • Understanding of accessibility (a11y), testing frameworks, and performance optimization.

      What can you expect from Sqills?

      • An enthusiastic, young, diverse group of ~240 colleagues worldwide;

      • A low sense of hierarchy, this comes with a lot of responsibility!

      • An open yet challenging environment of ambitious young professionals with different backgrounds;

      • Inspiring and fun outings with the entire company with colleagues from North America, Turkey, France and the Netherlands.
