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, motorsport, 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, MotorCAD, 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.
