JavaScript Engineer

Job Description

We’re looking for a JavaScript Engineer who writes pragmatic, scalable code and thrives in complex frontend environments. You’ll build advanced client applications, optimize performance, and collaborate deeply with backend teams. This role demands a strong grasp of modern JavaScript, thoughtful architecture, and a passion for clean, maintainable code. If you’re someone who digs into the details beyond “it works” and cares about the user experience and long-term code health, this role is for you.

Job Requirement

Who you are:

• A pragmatic problem solver who writes JavaScript that doesn’t just work — it scales, performs, and stays maintainable six months from now.
• Comfortable navigating complex codebases and unearthing subtle bugs in asynchronous code or tricky edge cases.
• Passionate about modern JavaScript ecosystems but know when to avoid over-engineering.
• Advocate for clean, readable code with meaningful comments and well-structured documentation.
• Not just a coder, but someone who thinks deeply about user experience, accessibility, and frontend performance trade-offs.

What you’ll own:

• Architect and build client-facing applications with complex state management, pushing the boundaries of what single-page applications can do.
• Collaborate closely with backend engineers to design APIs that are intuitive, robust, and future-proof.
• Write and maintain custom tooling and build scripts to optimize developer workflows and improve release pipelines.
• Identify and eliminate JavaScript performance bottlenecks — from network payloads to rendering lags.
• Lead code reviews focused on teaching, code clarity, and maintainability rather than just finding syntax errors.
• Help evolve the front-end testing strategy beyond basic unit tests — integrate end-to-end and visual regression tests.

Your toolkit (not all required, but you shine if you have these):

• Deep expertise in modern ES6+ features, asynchronous programming patterns (Promises, async/await, event loops).
• Experience with state management libraries beyond Redux (like Zustand, Recoil) or building your own patterns.
• Skilled in bundlers and build systems (Webpack, Rollup, Vite), and configuring them for code-splitting and tree-shaking.
• Practical knowledge of TypeScript or flow typing — not just typing variables but designing safe APIs.
• Experience debugging performance issues using browser dev tools, Lighthouse, or similar.
• Familiarity with React or Vue internals — not just component building, but understanding reconciler behavior, hooks lifecycles, or reactivity models.
• Prior experience setting up CI/CD pipelines for frontend projects.
• Comfortable working with GraphQL clients or REST with advanced caching layers.
• Passion for continuous learning — following emerging JS specs, tooling, and frontend trends.

Nice to have:

• Hands-on experience with WebAssembly or WASM interop in JS.
• Contributions to open source JavaScript projects or libraries.
• Experience building or maintaining design systems or component libraries.
