• Integrate with RESTful APIs and backend services, understanding data flows and performance implications
• Write clean, testable, and maintainable code following front-end best practices
• Participate actively in code reviews, providing thoughtful feedback and helping raise overall engineering quality
• Identify performance bottlenecks and apply profiling, benchmarking, and optimisation techniques
• Contribute to technical planning, estimation, and sprint execution
• Debug production issues and help improve reliability and user experience
• Stay up to date with modern front-end trends and apply them pragmatically where they add value

We're looking for a Senior Frontend Engineer who has:

• 10+ years of professional front-end development experience with strong hands-on expertise in React.js
• Excellent knowledge of TypeScript, JavaScript (ES6+), HTML5, and CSS3
• Experience with common tools and libraries in the React ecosystem (Redux, React Query, Zustand, or similar)
• Solid understanding of component-based architecture, state management, and modern front-end patterns
• Experience building responsive, performant, and user-friendly web applications
• Strong problem-solving skills with the ability to break down complex UI and state-management challenges into clean solutions
• Experience with performance profiling, debugging, and optimisation
• Familiarity with Git and modern development workflows
• Strong English communication skills and the ability to collaborate effectively with cross-functional teams
