Mechanical Technical Assurance– Cosy (Octopus Trusted Partners)

Help us make a big green dent in the universe. We're on a mission to drive the global renewable energy revolution, and we need loads more people to help us make our vision a reality.

We’re looking for a Technical Assurance professional to support our Octopus Trusted Partner (OTP) network as part of the Heat Pump team. The Cosy heat pump from Octopus Energy is our own in-house designed and built system - engineered end-to-end by us to deliver smarter, more efficient, low-carbon heating for homes. This hybrid role focuses on the mechanical safety, compliance, and quality of Cosy heat pump installations, requiring a solid understanding of ASHP systems and heating integration. You’ll play a key role in ensuring installations carried out by third parties meet expected mechanical and technical standards, supporting complex queries, and helping to resolve escalations effectively. You’ll act as a trusted technical point of contact between OTPs, technical design engineers, and wider Octopus Energy Services teams, ensuring issues are managed end-to-end and standards are upheld.
