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.
