Job Description

Principal Electro-Mechanical Engineer – Electric Machine & motors
Permanent
Greater Norwich Area
ARCA is proud to partner with an innovative engineering organisation at the forefront of next-generation electric propulsion technology.
This pioneering company is developing advanced electric machine solutions that are shaping the future of high-performance, efficient propulsion systems. As part of continued growth, they are seeking an experienced Principal Mechanical Engineer to play a leading role in the development of cutting-edge electric motor technology from concept through to production readiness.
This is an outstanding opportunity for a senior engineer with deep expertise in electric machine mechanical design, thermal management, and validation to join a highly collaborative and technically ambitious engineering environment.
The Opportunity
As Principal Mechanical Engineer, you will take ownership of the mechanical and thermal design of advanced electric motors, ensuring robust, manufacturable, and high-performing solutions capable of operating reliably in demanding real-world environments.
Working closely with multidisciplinary engineering teams across electromagnetic, controls, manufacturing, and testing, you will drive the full development lifecycle - from early-stage concept design through analysis, testing, validation, and transition into production.
Key Responsibilities
  * Lead the mechanical design and physical integration of electric machines
  * Design high-speed rotor systems including magnet selection, placement, and retention strategies
  * Develop robust shaft, bearing, and housing solutions
  * Define and implement air-cooled thermal management strategies
  * Integrate stator windings, insulation systems, flux rings, and sensing solutions
  * Conduct and guide mechanical, thermal, vibration, and tolerance analysis
  * Lead FMEA activities, root cause investigations, and design robustness reviews
  * Define and oversee structured validation and verification plans
  * Review and interpret test data to drive continuous design improvement
  * Ensure designs are manufacturable, scalable, and cost-effective
  * Support customer and stakeholder discussions with clear technical communication
What We’re Looking For
  * Proven experience in electric machine design with a strong focus on mechanical and thermal engineering
  * Motor experience
  * Extensive experience designing rotor systems for high-speed operation
  * Strong understanding of magnet retention methods and stator integration
  * Experience with motor build, testing, and validation activities
  * Knowledge of air-cooled thermal management systems
  * Experience leading FMEA and failure analysis processes
  * Familiarity with mechanical and thermal simulation/analysis tools
  * Strong understanding of materials used in electric machines, including electrical steels, magnets, and conductors
  * Ability to balance performance, durability, manufacturability, and cost considerations
  * Excellent communication and problem-solving skills
  * Degree qualified in Engineering or equivalent professional accreditation
Why Apply?
This is an exciting chance to join a forward-thinking engineering organisation developing next-generation propulsion technologies with real-world impact. You’ll work on technically challenging projects within a collaborative environment that values innovation, quality, and engineering excellence.
If you are a passionate mechanical engineer looking to take a leading role in advanced electric motor development, we would love to hear from you.
