Power Electronics Engineer (L2 / L3)

Job Description

Power electronics engineer shall provide technical support and subject matter expertise on power electronics, circuit design and analysis, electrification architecture & Motor controls. Develop power systems designs for spacecraft applications using modelling, simulation, and statistical design methods. Perform detailed component-level analysis to identify locations and operating conditions of high electromagnetic / thermal / mechanical stresses. Survey and investigate advanced circuit topologies component / board / packaging / manufacturing technologies to further improve circuit performance, fault-tolerance, and to reduce overall cost, weight, sizes. Collaborate with manufacturing engineers and suppliers to convert designs to production. Design, implement, and test new power electronic control software to meet documented requirements for power conversion products (drives, transformers, DC-DC converter) and programmable electronic fuses. Be responsible for technical direction and decisions for assigned product development projects. Work with a multi-disciplinary engineering development team that includes controls engineering, power conversion design, mechanical design, control hardware design, and Integration / Test. Test and debug of prototype and production power supply assemblies. Design verification testing of completed products. Develop mixed-mode circuits for power electronics applications, to achieve high accuracy, robustness, and low power consumption. Relevant degree such as Bachelors and Masters Degree in Electrical Engineering, Electronics, Power electronics Engineering, Electrical & Power Engineering. Power electronics circuit control and motor drive. Strong understanding of power electronics fundamentals is a must. Familiar with electromagnetic field measurement chambers and equipment. Hands-on experience designing, manufacturing, developing, or testing power electronic systems. Calculation and design of power chokes, inductors, and transformers. Calculation of power losses and efficiency optimization. Knowledge about different circuit test methods. It is preferrable to have experience with power conversion technologies (e.g., DC-DC converters, solar arrays, batteries) used in spacecraft power systems. Experience in designing power distribution and management systems for small satellites or CubeSats will be an added advantage. Familiarity with radiation-hardened electronics and mitigation strategies is desirable. Previous work experience involving spacecraft power systems is highly desirable. Proficiency in using simulation tools (e.g., SPICE, MATLAB/Simulink) for power electronics analysis and simulation Experience in designing and optimizing power distribution and management systems within spacecraft, including load sharing, fault tolerance, and redundancy strategies, is beneficial. Strong problem-solving skills and a proactive approach to innovation and optimization are highly valued. Experience in collaborating with cross-functional teams and interfacing with professionals from various disciplines (e.g., electrical, systems, mechanical engineering) is beneficial. Excellent working experience with Scopes, DVMs, Network Analyzers Strong understanding of conducted and radiated noise sources and their mitigation techniques in power electronic and analog systems. Experience in supervision of PCB layout for minimal stray parameters, power/signal plane definition for EMC optimization. Knowledge of Power Electronic Control algorithms including Matlab/Simulink Application.
