As a core member of the team, you will own the design of complex power conversion electronics, contributing significantly to innovative aerospace solutions that shape the future of space technology.

Responsibilities

• Conceptualise and develop high-power DC/DC converters tailored for satellite power applications, including component selection, gate drive circuits, magnetic design, and thermal management strategies.
• Design, simulate, and validate auxiliary power supplies and bias circuits, ensuring high efficiency and robustness in demanding environments.
• Perform comprehensive circuit simulations, including analysing switching losses, thermal profiles, and stability of control systems.
• Build physical prototypes, execute detailed testing, and refine designs based on lab results, ensuring performance meets stringent space standards.
• Collaborate with multidisciplinary teams to optimise electromagnetic compatibility (EMC) and minimise electromagnetic interference (EMI).
• Document designs, prepare technical reports, and support the integration process within aerospace frameworks.
• Hold a Master's degree or equivalent in electrical engineering or power electronics, complemented by at least five years of practical experience in converter design.
• Strong theoretical background in power conversion topologies, magnetics, and control algorithms.
• Proven expertise with wide-bandgap semiconductor devices such as SiC or GaN, including drive circuitry and high dv/dt layout considerations.
• Skilled in analogue circuit design, including sensors, amplifiers, and protective circuitry.
• Proficient in PCB design tools, particularly KiCad, with emphasis on power layout and EMI mitigation techniques.
• Demonstrated ability to independently operate and troubleshoot laboratory equipment such as oscilloscopes, power analyzers, and electronic loads.
• Analytical mindset, proactive approach, and excellent team-working skills.
• Experience working within the space, aerospace, or automotive sectors, particularly on high-reliability projects.
• Knowledge of photovoltaic power systems, including solar array behaviour and MPPT techniques.
• Familiarity with motor drive controls for stepper or BLDC motors.
• Basic embedded C programming skills for real-time control on DSPs or MCUs.
