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. Our customers are the installers who are at the forefront of this transition, but who have historically been overlooked and left struggling with outdated, ineffectual software.
Since getting started at beginning of 2024, we’ve grown exponentially, have raised several rounds of funding from top tier VCs, and now support over 500 heat pump installation businesses across the UK.
We’re looking for exceptional engineers at any level to help us move faster and go further as we start to expand outside heat pumps.
We’ve started with most challenging but ultimately most important part of the home energy transition: replacing boilers with heat pumps.
Nearly 20% of the UK’s carbon emissions come from heating homes. There is no credible path to net zero without replacing gas and oil boilers — and today, heat pumps are the only scalable alternative with their almost-magical ability to convert 1kW of electricity into 4kW of heat (🤯).
The problem? The installation process is slow, fragmented, and painfully manual. This increases costs for homeowners, limits how fast installation businesses can grow, and makes it almost impossible to offer a heat pump when someone’s boiler breaks down.
We’re fixing this. We’ve built an end-to-end operating system for heat pump installers — from initial enquiry through design and installation to compliance and paperwork. Relative to the best alternatives, Spruce now:
And we’re only just getting started. With fresh investment and growing demand, we’re now expanding into the rest of the home renewables supply chain – supporting manufacturers and merchants as well as installers, and enabling solar & battery installations alongside heat pumps.
You’ll work closely with a small, high-calibre team of engineers, designers, and domain experts to build and scale the tools that power the Spruce platform.

This is not CRUD-only work. You’ll be working meaningful production problems from day one that blends physical reality, real-world constraints, and serious impact.
Our tech stack strives for simplicity, symmetry and efficiency. Our hard problems come from the real world instead of self made architectural problems.
You don’t need to know all of the below but you do need an appetite for full stack mastery and owning the problem end to end.
We care less about titles and more about impact, judgment, and intent.
You’ll likely have experience with:
But more importantly, you are:
Whether you’re relatively early in your career or already operating at Senior level, you’ll find space here to do the best work of your career.
…and you’ll hopefully also love heat pumps! 🤓
