- Design and develop high-quality UIs, and strategically implement significant performance optimisations (e.g., Core Web Vitals, bundle size reduction).

- Establish and enforce best engineering and coding standards, driving code quality through rigorous code reviewing and mentorship.

- Proactively design monitoring/alerting strategies, leveraging Grafana and other monitoring tools to diagnose bottlenecks and ensure application stability.

- Actively mentor senior and junior engineers, fostering a culture of ownership and continuous technical learning.

- Lead cross-team collaboration with Product, UX, and Backend to define technical roadmaps and deliver integrated features.

- Set the standard for cross-browser compatibility and accessibility compliance across all UI components.

- Serve as a technical leader in the agile environment, influencing priorities and ensuring predictable feature delivery.

- Champion the effective and responsible use of AI-assisted development across the team, ensuring AI-generated code meets quality, testing, and security standards.

- Design resilient UI patterns for non-deterministic AI outputs — loading/”thinking” states, optimistic rendering, graceful fallbacks, and error/retry handling — to keep perceived performance high despite variable AI latency.

Who You Are:

- 8+ years of progressive front-end development experience, with a track record of leading and delivering large-scale, complex UI projects.

- Deep expertise in React, Typescript, and modern Vanilla Javascript (ES6+), with in-depth knowledge of framework internals and performance techniques.

- Proven experience with GraphQL, React Apollo, and state management libraries like Zustand, including designing efficient data architectures.

- Expertise in configuring and optimizing build pipelines using module bundlers/build tools such as Vite or Webpack, and experience with lerna or similar monorepo management.

- Excellent debugging skills with the ability to diagnose and resolve production issues across the entire stack.
