Job Title: Principal Power Electronics Engineer – Aerospace Location: Cardiff Employment Type: Permanent Industry: Aerospace / Power Electronics Overview: We are seeking an accomplished Principal Power Electronics Engineer to lead the design and development of advanced power conversion systems for aerospace applications. This is a senior-level role suited for an individual with a proven track record in DC/DC, AC/DC, and DC/AC converter design, and deep technical expertise in wide bandgap semiconductors (SiC/GaN) and magnetics. Key Responsibilities: Lead the design, development, and validation of high-reliability power converters for aerospace systems. Architect and simulate topologies for DC/DC, AC/DC, and DC/AC power conversion. Select and evaluate SiC and GaN devices for high-efficiency, high-density designs. Design custom magnetics, including transformers and inductors, optimised for weight, size, and thermal constraints. Guide thermal and EMI/EMC compliance considerations through the design lifecycle. Drive system-level trade-off studies and influence hardware architecture decisions. Provide technical leadership and mentorship to junior engineers within the power electronics team. Support qualification and certification activities in line with aerospace standards (DO-160, MIL-STD, etc.). Interface with systems, mechanical, and software teams to ensure seamless product integration. Required Qualifications: Degree in Electrical or Electronic Engineering (Master’s or PhD preferred). In-depth experience in power electronics, with recent experience in aerospace or high-reliability sectors. Deep knowledge of DC/DC, AC/DC, and DC/AC power converters, including resonant and hard/soft-switching topologies. Strong experience working with SiC and GaN technologies in high-voltage, high-frequency applications. Expertise in magnetics design, including planar and high-efficiency magnetic components. Proficiency with simulation and development tools such as PLECS, LTspice, MATLAB/Simulink, and Altium or similar CAD platforms. Familiarity with aerospace design standards and environmental constraints. Preferred Experience: Background in airborne or spaceborne power systems. Experience with radiation-hardened designs or redundant architectures. Knowledge of safety-critical design practices and lifecycle documentation. If this Principal Power Electronics Engineer is of interest, then please apply with an up-to-date CV and contact information.
