We’ve grown incredibly quickly over 2024 and with hundreds of new customers, we’re now on the hunt for a phenomenal, experienced full-stack developer who’s pumped to help drive the transition away from fossil fuel heating in homes.
🌲 About Spruce
- Almost 20% of the UK’s carbon emissions comes from heating homes. There’s simply no way to make meaningful progress towards net zero without accelerating the phase out of gas and oil boilers. Excitingly, heat pumps are a pretty amazing alternative, with their almost-magical ability to turn 1 kW of electricity into 3-5 kW of heat (🤯), not only slashing carbon output but reducing homeowner bills too.
- But there’s a problem: the heat pump installation journey is slow, inefficient, and just so painful for installers. This makes it really hard for existing heat pump installers to grow their businesses and unappealing for boiler installers to transition to heat pumps. Meanwhile homeowners get frustrated with slow response times and conflicting advice, having to plan months ahead if they want to make the switch.
- We’re fixing this. We’ve built an operating system for heat pump installers to manage the whole installation journey from initial enquiry through to final compliance paperwork, freeing up their time to focus on what really matters: doing high-quality installations, providing great customer service, and scaling their businesses.
- We’re already having a massive impact on over 300 installation businesses across the UK, halving the time they spend on each installation and helping them win more jobs in the process. And we’re barely scratching the surface – there’s so much more for us to do as we look to transform not just the business of heat pumps, but the whole home renewables supply chain.
- We’re currently a team of 8, split evenly between London and Bristol. We spend a few days each week working together in-person in both locations, and get everyone together every fortnight.
🥖 The Role
You’ll work alongside Steph, Nick, Raph, Dan, and Ilya to build the various tools that make up the installer OS. These include an automated heat pump estimator, a survey app to speedily collect and process data from people’s homes, and a tool to create optimally efficient designs for each property.
You’ll be exposed to a wide variety of problem spaces including:
- Designing hydronic systems and modelling building heat loss
- Building a 2D and 3D floorplan creator, perhaps with the help of LiDAR and computer vision
- Scraping and large-scale data consolidation to provide country-wide datasets
- Offline-first and PWA applications (potentially extending to native apps)
- Integrating with hardware such as bluetooth laser measures, sensors, and heat pump monitoring systems
