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.

• 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:
  Type Script excellence, testing, CI/CD, performance
• Mentoring front‑end engineers + shaping team culture

• Expert React + Type Script (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

• Micro‑frontend patterns (Module Federation, single‑spa)
