Lead Software Engineer

Lead Frontend Engineer – Climate Tech – London / Cambridge

Take ownership of front-end engineering at a growing climate‑tech company shaping the future of energy planning. You’ll lead the move from a monolithic UI to a modern micro‑frontend architecture – while building a high‑quality engineering culture from the ground up.

This role is hands‑on. You’ll work directly with the CTO, steer architectural decisions, and mentor a growing team. If you enjoy solving complex front‑end challenges, scaling modern React systems, and building high‑performance data and geospatial visualisations, this is an opportunity to lead with impact.

What you’ll lead

• The migration to a micro‑frontend architecture
• The creation of a reusable design system + component library
• High‑performance geospatial visualisation (DeckGL, WebGL)
• Front‑end standards: TypeScript excellence, testing, CI/CD, performance
• Mentoring front‑end engineers + shaping team culture

What you bring

• Expert React + TypeScript (4+ years), 2+ years leading engineers
• Strong architecture background – ideally micro‑frontends
• Experience with complex data visualisation or geospatial tools (DeckGL/Mapbox)
• Knowledge of modern bundlers (Vite, Webpack, esbuild)
• Focus on performance, modularity, and scalable front‑end systems

Nice to have

• Micro‑frontend patterns (Module Federation, single‑spa)
• D3/Plotly/Recharts, AWS, testing frameworks
