Position: Senior Mechanical Design Engineer (Renewable  Systems)
Location: London/ Hybrid
Salary: £75,000 - £90,000

We are looking for a specialist Mechanical Design Engineer to lead the transition from fossil fuel combustion to Large-Scale Heat Pump Technology. You will be responsible for the physics of the system—ensuring that high-capacity heat pumps are integrated into hydronic circuits that actually deliver on their efficiency promises.

Core Technology Focus1. Air Source Heat Pumps (ASHP)
Cascade Systems: Designing multi-unit ASHP arrays for commercial peak loads.
Defrost & Ambient Logic: Managing acoustic mitigation, airflow requirements, and defrost cycle impacts on system continuity.
Bivalent Integration: Designing systems that integrate ASHPs with existing LTHW or backup heat sources. 2. Ground Source Heat Pumps (GSHP)
Array Design: Coordinating borehole heat exchangers (BHE), horizontal loops, and thermal conductivity testing.
