• Contribute to design, UX, performance optimisation, and frontend architecture decisions
• Work as part of a cross-functional team with product, engineering, and domain experts

What you’ll bring

• Strong React and TypeScript experience
• Experience building low-latency, data-rich interfaces that update in real time
• Ability to simplify complex problems into elegant, intuitive user experiences
• Strong communication skills and a collaborative mindset
• Experience with testing, CI/CD, and modern engineering practices
