Senior Power Electronics Engineer

CesiumAstro•Westminster, CO

About The Position

CesiumAstro is seeking a Senior Power Electronics Engineer to develop power electronics for satellites, spacecraft, and aerospace systems. The role involves full-stack development, from concept development through detailed design, analysis, board layout, testing, and delivery. The engineer will contribute directly to the business in a startup environment while applying technical rigor to high-reliability space and airborne products. The successful candidate will present engineering design review materials to customers and the executive team.

Requirements

Bachelor of Science degree or higher in Electrical Engineering from an accredited university.
At least 5 years of industry or university research experience in board-level power electronics design, analysis, and testing.
Experience owning power electronics or power subsystem design, including power architecture and requirements definition, trade studies, power converter and analog electronics design, component selection, and detailed design.
Experience performing or guiding complex PCB layout for analog and power electronics.
Experience with analysis and simulation tools such as SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, or MathCAD.
Strong laboratory testing and troubleshooting experience for prototyping, design verification testing, and qualification of analog and power electronics hardware.
Direct experience designing high-reliability electronics for automotive, space, or defense applications, including component derating, worst-case analysis, and thermal constraints.
Excellent written and verbal communication skills.
Must be a U.S. citizen, lawful permanent resident, conditional resident, asylee, refugee, or eligible to obtain required U.S. Department of State authorizations, in accordance with U.S. Government Space Technology Export Regulations.

Nice To Haves

Experience delivering subcircuit or board designs to production and deployment.
Proficiency with PCB design tools such as Altium, OrCAD/Allegro, PADS/Xpedition, or similar.
Experience running board-level power integrity simulation tools such as Ansys SiWave, ADS SIPro, or HyperLynx.
Experience designing for space radiation environments.

Responsibilities

Own end-to-end design of power converters and power management and control circuits, from concept and architecture definition through schematic design, PCB design, testing, qualification, production transition, and production support.
Create detailed schematics for low- to high-complexity power electronics, including individual converters, multi-output power supply modules, and power management circuitry.
Perform detailed PCB layout in Altium Designer independently or in collaboration with a PCB Drafter.
Model and analyze analog and power electronics designs, including worst-case circuit, stress, small-signal and stability, power loss and efficiency optimization, and power integrity analyses.
Develop design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans.
Bring up and perform design verification testing of power electronics circuits and modules, often working with a technician or junior engineer.
Collaborate with the multidisciplinary engineering team, lead system integration and qualification campaigns, and release analog and power electronics designs to production.
Mentor junior engineers and support their technical understanding and professional development.
Research power electronics technology and industry trends to drive innovation and intellectual property generation.
Present engineering design review materials to customers and the executive team.
