Senior Electromagnetic Design Engineer

Senior Electromagnetic Design Engineer Reading Up to £85,000  Generous Stock Options KO2's client is a cutting-edge, well-funded, rapidly scaling technology startup developing next-generation electric propulsion and advanced motor technologies. Backed by significant investment and ambitious growth plans, they are building a world-class engineering team to tackle some of the most challenging problems in electrification and sustainable mobility. This is a rare opportunity to have a direct impact on the development of revolutionary electric machine technologies while working in a highly innovative and fast-paced environment.

As a Senior Electromagnetic Design Engineer, you will lead the design, simulation, optimisation, and validation of advanced electric machines for high-performance applications. You'll work on breakthrough technologies that push the boundaries of power density, efficiency, and reliability, helping bring innovative products from concept through to real-world deployment. Working closely with multidisciplinary teams across mechanical, thermal, controls, systems, and validation engineering, you'll play a key role in shaping the company's future products and technology roadmap.

Key responsibilities include:

Design and develop advanced electric machines including PMSM, IPM, Halbach array, and Vernier motor topologies. Lead electromagnetic design activities for high-power electric propulsion systems and next-generation electrification products. Perform detailed electromagnetic analysis, simulation, and optimisation to maximise performance, efficiency, and power density. Conduct loss modelling including iron losses, permanent magnet losses, AC copper losses, and thermal performance assessments. Perform fault and failure mode analysis, including short-circuit conditions, inverter faults, demagnetisation studies, and unbalanced magnetic force investigations.

Develop analytical and simulation models to support design decisions and product development. Drive optimisation studies using advanced tools and techniques including parametric design, sensitivity analysis, and automated workflows. Support prototype development, testing, validation, and continuous product improvement. Collaborate with cross-functional teams to deliver innovative, robust, and manufacturable engineering solutions. Contribute to technical innovation, intellectual property generation, and future technology development.

What We're Looking For We're seeking an engineer who combines deep technical expertise with a passion for innovation. You'll ideally have:
Significant experience in electromagnetic design of electric machines within aerospace, automotive, motor sport, energy, or advanced technology sectors. Strong expertise in PMSM, IPM, Halbach, Vernier, and other advanced machine topologies. Experience developing high-power, high-speed, or high-performance electric propulsion systems. Advanced simulation experience using tools such as Ansys Maxwell, Motor

CAD, JMAG, Simcenter 3D, or equivalent.

Experience with optimisation platforms including OptiSLang, Siemens HEEDS, or similar. Strong understanding of machine losses, electromagnetic performance, and efficiency optimisation. Why Join? Join a well-funded startup at a pivotal stage of growth. Work on genuinely innovative technology with real-world impact. Influence technical direction and product development from an early stage. Collaborate with a highly talented team of engineers and industry experts.

Exposure to cutting-edge electrification and propulsion technologies. Excellent opportunities for career progression as the company scales. Competitive salary, benefits package, and the opportunity to be part of an exciting growth story. If you're an experienced Electromagnetic Design Engineer looking to join a business where your work will directly shape the future of electric propulsion technology, KO2's client would be delighted to hear from you.
