We’re on a mission to make it simple and affordable for every home in the UK to be heated and powered by clean, green electricity. We're looking for an exceptional Lead Engineer to help us move faster and go further as we start to expand outside heat pumps.

Requirements

• Own architecture and technical strategy for a core domain or set of systems.

• Lead technical discussions, make trade-offs explicit, and help teams align.
• Mentor senior engineers and develop others into technical leaders.
• Coach engineers in how to make decisions, rather than making every decision yourself.
• Proactively identify scaling risks, bottlenecks, and areas of technical debt — and drive solutions.

• £90–130k salary (depending on experience, impact, and location)
• Meaningful slice of equity (options) in the company
• 33 days holiday and opportunity to work from abroad for another 30 days each year
