Job Description

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.
