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.

REQUIREMENTS

You’ll have at least 2 years development experience and will have an excellent understanding of:

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

On top of that you’ll be:

• 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!

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.
