Senior Power Electronics Engineer

Harmattan AI is a leading defense company specializing in autonomous and scalable defense systems. The company is expanding its capabilities following a significant investment, aiming to deliver mission-critical systems to allied forces. The role of a Senior Power Electronics Engineer is crucial for the development of power electronics, which are essential for the performance and reliability of their unmanned aerial systems (UAS). The main responsibilities of the Senior Power Electronics Engineer include leading the design and development of power stage architectures, such as motor controllers and DC-DC topologies, across various UXV platforms. This involves translating mission constraints into power-chain specifications, designing analog switching, and conducting multi-fidelity simulations. The engineer will also be responsible for designing high-power-density PCBA, ensuring EMI/EMC compliance, and managing the transition from prototype to production. Additionally, the role involves lab validation, firmware and controls interface, and mentoring junior engineers. To qualify for this role, candidates must have an MSc or PhD in Electrical Engineering, Power Electronics, or a related field, along with at least five years of hands-on R&D experience in motor drives, BLDC/PMSM controllers, or high-power-density power electronics. Proficiency in MOSFET commutation design, simulation tools like LTspice, PLECS, or Simulink, and PCB design using Altium are essential. Fluency in English is required, and experience with GaN/SiC, safety-critical design, and applied control theory is a plus. The role is based in Lausanne, Switzerland, and offers the opportunity to work in a dynamic and challenging environment with a focus on innovation and excellence. The team at Harmattan AI values rigor, ownership, and execution, providing a supportive environment for professional growth. The role offers the chance to work on cutting-edge technology and contribute to the development of autonomous defense systems. The company's commitment to excellence and ambition makes it an exciting place to build a career in power electronics. What the role asks for: - MSc or PhD in Electrical Engineering, Power Electronics, or equivalent. - 5+ years of hands-on R&D experience on motor drives, BLDC/PMSM controllers, or high-power-density power electronics. - Deep working mastery of MOSFET commutation design. - Proven ownership of at least one motor-controller PCBA shipped from prototype through production. - Fluency in simulation (LTspice, PLECS, or Simulink) and PCB design (Altium). - Fluency in English. - Nice-to-have: GaN / SiC experience.
