Senior Mechanical Design Engineer
Location: West Midlands (Hybrid – 2 days on site)
Salary: £50,000 – £65,000
Job Type: Permanent
Industry: Mechanical Design / EV / High‑Power Systems
Overview
An exciting opportunity for an experienced Senior Mechanical Design Engineer to join a rapidly growing engineering business developing next‑generation high‑power DC charging systems for commercial electric vehicles.
You’ll work on complex electro‑mechanical and thermal systems, taking designs from concept through prototype and into pre-production. Ideal for engineers with strong CAD, thermal management, liquid cooling and electro‑mechanical design experience.
The Role
* Lead mechanical design of high‑power charging systems (350kW–1MW+)
* Create concepts, detailed designs and prototype assemblies
* Design liquid cooling systems, heat exchangers and thermal management solutions
* Produce CAD models, drawings and engineering documentation
* Complete feasibility studies, packaging and system integration
* Support prototype builds, testing and commissioning
* Improve manufacturability (DFM/DFA) and product reliability
* Collaborate with electronics, systems and manufacturing teams
* Mentor junior engineers and support process development
Required Experience
* Strong mechanical design background in electro‑mechanical, thermal or high‑power systems
* Experience with liquid cooling, thermal management or fluid systems
* Proven track record taking products from concept to prototype and pre‑production
* CAD proficiency (any major package) + PDM/PLM experience
* Understanding of DFM/DFA and supplier/manufacturing processes
* Hands‑on experience with prototype builds, test rigs or assemblies
Desirable
* EV charging, power electronics or HV equipment exposure
* Experience in regulated/technical environments (medical, automotive, aerospace)
* Knowledge of validation testing, instrumentation and data analysis
* Start‑up or scale‑up engineering environment experience
