Role

You will own end-to-end power electronics development for satellites, spacecraft, and aerospace systems. Starting at concept and progressing through detailed design, analysis, board layout, testing, and delivery, you'll do hands-on work at each phase. Your designs will directly impact product success and must meet high-reliability space and airborne standards.

You will present engineering design review materials to customers and the executive team, requiring excellent written and verbal communication skills.

Responsibilities

  • Own end-to-end design of power converters and power management circuits from concept and architecture definition to schematic, PCB design, testing, qualification, production transition 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.
  • Perform detailed PCB layout in Altium Designer independently or 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.
  • Collaborate with multi-discipline engineering teams and lead system integration and qualification campaigns.
  • 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 5 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 running board-level power integrity simulation tools such as Ansys SiWave, ADS SIPro, or HyperLynx.
  • Design for space radiation environments.

Employment

Full-time position. CesiumAstro offers company stock options and a benefits package including health, dental, vision, HSA, FSA, life, disability and retirement plans.
