Principal Mechanical Engineer
We’re working with an innovative engineering business developing advanced technology for the next generation of electrified and high-performance mobility.
As the business continues to expand its engineering capabilities, they are looking for an experienced Principal Mechanical Engineer to join the team and take ownership of the mechanical design, thermal performance and physical integration of complex electromechanical systems.
This is a highly technical role spanning the full development lifecycle — from initial concept and detailed design through analysis, testing, validation and production readiness.
The Role
You’ll be responsible for delivering robust, manufacturable designs that perform reliably under demanding real-world conditions.
Your responsibilities will include:
- Leading the mechanical design and physical integration of complex electromechanical systems.
- Developing rotating assemblies, retention systems, shafts, bearings and housings.
- Ensuring structural integrity during high-speed operation, including burst strength, fatigue and containment.
- Developing air-cooled thermal management strategies, including cooling paths, airflow management, thermal interfaces and material selection.
- Working with permanent magnet, flux management, winding and insulation technologies.
- Integrating speed, position and temperature sensing solutions.
- Working closely with electromagnetic and controls engineers to translate performance targets into practical, manufacturable designs.
- Leading and contributing to mechanical, thermal and dynamic analysis, including stress, deformation, rotor dynamics, balance, vibration and heat flow.
- Carrying out tolerance stack-up and manufacturability assessments.
- Leading FMEA, failure analysis, root-cause investigations and corrective actions.
- Defining and owning structured test and validation programmes.
- Working with the test team to develop clear, executable test plans, instrumentation requirements and test setups.
- Reviewing test data to validate design intent and drive design improvements.
- Ensuring designs are suitable for manufacture and production scale-up, considering assembly, tooling, materials, supply chain and cost.
- Supporting internal and customer-facing activities, communicating technical decisions, trade-offs and performance outcomes.
