The Frontend Developer will lead front-end development, collaborate with design and backend teams, optimize websites, and maintain code quality. This role requires strong skills in UI component creation, JavaScript, debugging, and experience with modern frameworks and APIs.
We’re looking for a front-end developer who not only knows how to build beautiful interfaces but also understands the importance of performance, maintainability, and debugging. This role goes beyond just implementing a design — we’re looking for someone with a deep appreciation for interface quality and detail. You should be comfortable translating Figma files into pixel-perfect, responsive layouts (SCSS preferred), while also thinking critically about how interactions feel and behave across breakpoints and states., efficient JavaScript code that scales.
You should feel confident working with modern JS libraries and performance optimization techniques, be comfortable debugging across browsers and devices, and bring strong fundamentals in programming logic and architecture. The right person is curious, proactive, and constantly striving to refine their code and processes — someone who enjoys solving both visual and technical challenges.
If you’ve ever explored topics like dynamic imports, asset preloading, performance auditing, animation cleanup, WebGL rendering, GTM integration in SPAs, or structuring code into abstract, reusable modules — or if terms like CLS, FCP, lazy loading, deferring scripts, reducing bundle size, and optimizing rendering are part of your everyday vocabulary — we’d love to hear from you.
