JavaScript Engineer

Job Description

We’re looking for a JavaScript Engineer who thrives on solving real-world problems at scale. This role isn’t about building basic CRUD apps — it’s about architecting fast, secure, and maintainable browser-based solutions that push performance boundaries. You’ll work closely with backend engineers, designers, and product managers to build complex interactions, real-time interfaces, and highly responsive UIs that serve thousands of concurrent users. If you’ve ever optimized bundle sizes to shave milliseconds or used Web Workers to offload CPU-heavy logic, this job is for you.

This position reports to the Frontend Lead and offers the opportunity to own features end-to-end, from prototype to production.

Responsibilities:

• Architect and implement reusable, testable components using modern JavaScript (ES2020+)
• Collaborate with design and product teams to deliver pixel-accurate, interactive interfaces
• Optimize performance for low-latency UI updates and complex client-side state
• Write unit and integration tests using frameworks like Vitest or Jest
• Work across the stack when needed — particularly when data shaping is required for frontend use
• Participate in peer code reviews with an emphasis on readability, maintainability, and performance
• Help shape internal frontend standards around tooling, state management, and design systems

Qualifications:

• 4+ years of professional experience with JavaScript, including deep familiarity with at least one modern framework (React, Vue, Svelte, or SolidJS)
• Strong understanding of the JavaScript runtime — closures, event loop, garbage collection, memory profiling
• Experience using Vite, Webpack, or similar tools to fine-tune build processes
• Comfortable writing vanilla JavaScript where frameworks fall short
• Experience debugging browser quirks and performance bottlenecks using Chrome DevTools
• Familiarity with state management libraries (e.g., Zustand, Pinia, Redux Toolkit, or MobX)
• Understanding of WebSockets, Service Workers, or WebAssembly a plus
• Comfortable with TypeScript in strongly-typed codebases (optional but highly preferred)
• Prior experience contributing to design systems or working within one
• Bonus: Experience with canvas or WebGL rendering (e.g., for data visualizations or games)

Nice to Have:

• Contributed to open-source JavaScript libraries or tooling
• Built progressive web apps (PWAs) with offline support
• Familiarity with accessibility (ARIA roles, screen readers, etc.)
