Power Electronics Engineer III

About the role

This role is part of the Blue National Security business unit, focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit.

Responsibilities

• Capture and translate engineering requirements and customer specifications for power electronic systems for space applications.
• Perform conceptual design, including selection of power-stage topology and control schemes suitable for challenging aerospace environments.
• Execute detailed design, selecting reliable and space-qualified components to meet demanding performance and environmental criteria.
• Develop and implement controller algorithms to optimize converter performance and efficiency.
• Conduct feasibility studies and verify designs through detailed circuit simulation and analysis.
• Produce accurate and clear schematic drawings for power electronic circuits.
• Design PCB layouts and perform routing to meet space application standards, including reliability and manufacturability.
• Lead board bring-up, troubleshooting, and functional testing of prototypes and production units.
• Perform iterative design improvements based on test data and feedback, ensuring readiness for production.
• Collaborate with cross-functional teams, including firmware, mechanical, and systems engineering, to ensure cohesive product development.
• Support documentation, design reviews, and production transition activities.

Qualifications

• Bachelor’s degree in Electrical Engineering or related field.
• Minimum 5 years of experience designing power electronics for aerospace or space applications (DC-DC converters essential).
• Proven track record designing DC-DC converters, both with and without galvanic isolation, control algorithms.
• Experienced in selecting power-stage topologies and control schemes, including both isolated and non-isolated DC-DC converters.
• Hands-on experience with components selection for demanding environments.
• Strong skills in controller algorithm design and implementation.
• Proficient in circuit simulation tools (e.g., LTspice, PSpice, SIMetrix) for feasibility and verification, including transient analysis, in-rush analysis, stress analysis and stability analysis.
• Experience in schematic capture (e.g., Altium Designer, OrCAD) and PCB layout/routing for high-reliability electronics.
• Experience with Si, GaN and SiC devices.
• Demonstrated ability to bring-up boards, troubleshoot, and validate performance through testing.
• Experience iterating designs for manufacturability and reliability in a production environment.
