• Hands-on experience with WebGL, three.js or React Three Fiber, including scene and camera control, pointer picking and animation timelines.

• Experience managing events and interaction across layered UI and graphics surfaces.

• Experience integrating map SDKs, handling coordinate systems, implementing provider fallbacks and managing API tokens safely.

• Ability to build components that integrate into an existing host application through clean props and callbacks, isolated styles and no unintended global side effects.

• Strong testing experience with Vitest or Jest and React Testing Library, supported by a practical test strategy.

• Experience with strict TypeScript, error boundaries, cross-browser testing and browser DevTools.

• Experience contributing to CI/CD pipelines, Git workflows and high-quality pull-request reviews.

• Experience with Azure DevOps

• Proven technical leadership through mentoring, task breakdown, estimation and technical documentation.

• Understanding of front-end security fundamentals, including secure environment configuration, safe logging and responsible third-party dependency use.

Good to Have Skills

• Experience with advanced animation libraries such as GSAP or Framer Motion.

• Experience with charting and data-visualisation libraries.

• Experience with visual regression testing or end-to-end testing using Playwright

• Experience with internationalisation and localisation at scale.
