Base pay range

We've gone from 0 to 400+ customers in under 18 months, with strong signs of product-market fit and a big mission: to make heat pump installations faster, easier, and more scalable across the UK. Now we're looking for a Full Stack Engineer to join our team of 10 and drive the next phase of growth.

Quick background on Spruce

Almost 20% of the UK's carbon emissions comes from heating homes - there's simply no way to make reach net zero without phasing out gas and oil boilers. Right now the only serious alternative is heat pumps, with their almost-magical ability to turn 1 kW of electricity into 3-5 kW of heat (). But there's a problem: the heat pump installation journey is slow, inefficient, and just so painful. This makes it really hard for existing installers to grow their businesses and puts off gas engineers from starting to do heat pumps. Perhaps most critically, it means you can't currently offer a heat pump when someone's boiler breaks and they urgently need heating.

We're fixing this. We've built a platform 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 business. Despite only getting started at the beginning of 2024, we're having a massive impact on installation businesses, suppliers, and manufacturers across the UK: halving the time they spend on each job, doubling their sales conversion rates, and boosting their bottom line.

Having now raised further investment, we're in the process of scaling the team to massively grow our impact. We ultimately want to build an operating system for the whole home renewables supply chain. Picture a combination of ServiceTitan, Procore, and autoCAD and you might get a sense of where we're headed...

The Role

You'll work alongside Steph, Nick, Emma, Kieran, Raph, and Dan and the rest of team to build the various tools that make up the installer OS. 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, with the help of LiDAR and computer vision
• Scraping and large-scale data consolidation to provide country-wide datasets
• Offline-first and PWA applications with multiple users collaborating simultaneously
• Integrating with hardware such as bluetooth laser measures, sensors, and heat pump monitoring systems
  
  

• Docker, Docker Compose
• PostGIS, Atlas migrations
• Node, Prisma
• React, Typescript, Konva, Tailwind
  
  

• Node, React, and Typescript
• Relational database design and SQL
• REST APIs
• Distributed systems and their associated problems
• Scalable architecture and security
  
  

• Product-minded - you want to properly understand the problem you're solving and the people you're solving it for. You push forward change in anyway you can, from updating Figma designs to talking to customers directly
• Impact-focussed - you want to make a big impact with your work, balancing high-quality code and technical debt with the need to deliver new features to our customers - and you'll take pride in seeing the difference our tools make for installers
• Team-oriented - you're a unifying and collaborative force, not a lone wolf. The idea of spending some time in person with the rest of the team feels exciting and not a chore
• and you'll hopefully also love heat pumps!
  
  

• We're currently a close-knit team of 10, split between London and Bristol. We spend 2-3 days each week working together in-person in both locations, and get everyone altogether every fortnight
• You'll have genuine influence from day one. The best idea wins regardless of seniority. We expect you to challenge everything, ask "why?" multiple levels deep, and push back when something doesn't make sense
• We want everyone to spend time with installers on-site, feel their pain points, then be able to rapidly suggest and implement solutions based on real feedback rather than assumptions
• We move fast and ship imperfect things, learning from users rather than trying to perfect in isolation. When things break, we focus on how we fix it, what can we learn and never blame. You'll own your outcomes whilst knowing the team has your back
• Feedback is constant, direct, and kind - we'll tell you when something isn't working and expect the same honesty (and empathy) back
