Lead Software Engineer

Lead Full Stack Engineer | Climate Tech | £110k–£130k + Equity | Hybrid (London / Bristol)

Join a VC-backed, high-growth startup solving one of the UK’s biggest problems — decarbonising home heating.

They’re building the operating system powering heat pump installs across the UK — already used by 500+ businesses — and now scaling fast into broader renewables (solar, battery, etc.).

Real product. Real customers. Real impact.

• Work directly with product on what to build, not just how
• Spot scaling issues early and fix them
• Mentor engineers and raise the bar
