• You drive the evolution of our React-based frontend, including state management, server-side rendering with Node.js, and modern build and deployment tooling
• You define and uphold engineering standards across code quality, testing, performance, accessibility, and security
• You make sound technical decisions and ensure strong alignment with backend, platform, and product architecture
• You lead, coach, and develop a team of frontend engineers, including hiring, onboarding, performance development, and career growth
• You foster a high-trust, high-accountability engineering culture focused on feedback, learning, ownership, and craftsmanship
• You enable collaboration, pairing, knowledge sharing, and continuous improvement within the team
• You act as the primary frontend point of contact for Product, Design, and Engineering leadership
• You support the transition from functionally separated teams to cross-functional, value-aligned teams where it makes sense
• You own frontend delivery outcomes, ensuring predictable planning, prioritisation, quality, and execution
• You work closely with Product Management and Design to translate business and user needs into executable technical roadmaps
• You balance feature delivery, platform evolution, and technical debt in a sustainable way
