Senior Front End Developer

You will join our team of developers working on the next generations of on Easy PV and Heatpünk, our web tools for designing PV and heat pump systems. As a senior developer in the team you will manage and mentor some of our younger developers - so we're looking for someone who is not just an excellent developer, but a great leader too. Some of the areas you will work on are:

• 2D and 3D graphical design tools. Within Easy PV, users interact with several 2D and 3D editors to create buildings, add and view solar arrays, and create schematics. In Heatpunk users create floorplans and we are working on a 3D editor to create pipe runs. These are complex pieces of UI, but have to be easy to operate and understand.

• UI design and implementation. We are in the midst of a big project to bring all the UI in Easy PV and Heatpunk into a new design system. You will work closely with our UI designer to complete this task, and ensure that all new elements that we add in the future are also consistent in style and function.

• Core functionality. Solar and heat pump systems are complex, and for responsiveness we carry out many calculations and optimisations in the browser. At times you will need to dig deep into the core logic of the application.

• Customisation. We create and curate customised versions of Easy PV and Heatpunk for a number of customers, including large installers, manufacturers and energy companies. You'll get to work on interesting projects for some big household names.

The role is based in our offices in Milton, on the outskirts of Cambridge.
