Senior Power Electronics Engineer II Verified today

About CesiumAstro

CesiumAstro develops communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We operate in a dynamic, cross-functional startup environment where your work directly impacts business success.

The Role

As Senior Power Electronics Engineer II, you will own full-stack power electronics development. You will work hands-on from concept development through detailed design, analysis, board layout, testing, and delivery. Your designs will be challenged with high technical rigor for space and airborne high-reliability applications, while maintaining startup agility.

You will also present engineering design review materials to customers and executive team.

Key Responsibilities

• Own end-to-end design of power converters, power management and control circuits from concept and architecture definition through schematic, PCB design, testing, qualification, and production support.
• Perform detailed schematic design for low to high complexity power electronics, ranging from single power converters to multi-output power supply modules and power management circuitry.
• Perform detailed PCB layout in Altium Designer independently or in collaboration with a PCB Drafter.
• Perform modeling and analysis including worst-case circuit analysis, stress analysis, small signal and stability analysis, power loss and efficiency optimization, and power integrity analysis.
• Develop design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans.
• Perform bring-up and design verification testing of power electronics circuits and modules, working with technicians or junior engineers.
• Collaborate with multi-discipline engineering teams on system integration, qualification campaigns, and production release.
• Mentor junior engineers and foster professional development.
• Research new power electronics technology and industry trends to drive innovation and intellectual property generation.

Required Qualifications

• Bachelor of Science degree or higher in Electrical Engineering from an accredited university.
• Minimum 6 years of industry or university research experience in board-level power electronics design, analysis, and test.
• Experience owning the design phase of power electronics or power subsystems, including power architecture, 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 part derating, worst-case analysis, and thermal constraints.
• Excellent written and verbal communication skills.

Preferred Experience

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

Compensation and Benefits

Full-time employment offers include company stock options and benefits: health, dental, vision, HSA, FSA, life, disability and retirement plans.
