Service Engineer

Location: M4 corridor – between Bristol and Swindon

Salary: £35,000 -£45,000

We are a rapidly growing CleanTech business looking to disrupt the heating industry with a new kind of low-carbon boiler technology. Decarbonisation of domestic heating is the single biggest challenge facing the UK’s goal to reach Net Zero. Heating represents over 17% of all carbon emissions in the UK.

Our product is a new type of low carbon heating technology which is becoming a game changer in the drive to decarbonise domestic heating. It’s called a Zero Emission Boiler (ZEB)® and is a direct replacement for a gas or oil boiler. It uses electricity to ‘charge’ ultra-high density thermal storage when energy prices and the carbon intensity of the grid are low. Our IoT technology and cloud-based algorithms automatically optimise the ZEB to minimise cost & carbon. The ZEB operates like a normal boiler for our customers, is easy to install and massively reduces the carbon emissions from heating.

We’ve been recognised as one of the fastest growing and most exciting CleanTech scale-ups in the UK and were recently featured on the Everything Electric Show. There’s more on our website at

About the role

At tepeo, we are committed to creating a diverse and inclusive workplace where everyone feels welcome and valued. We are recruiting for a Service Engineer to join our growing Field Operations team.
