If you enjoy working in a startup environment and are passionate about developing leading-edge power electronics for satellites, spacecraft, and aerospace systems, we would like to hear from you.\nAt the Senior level, you will be tasked with full-stack power electronics development. You will have the opportunity to start at concept development and progress through detailed design, analysis, board layout, testing, and delivery, doing hands-on work at each phase.\nAt a small company and a startup, your work will make direct contributions to the success of the business. The work is challenging and impactful, requiring both breadth and depth of technical knowledge. Our products are made for high-reliability space and airborne applications, so designs require high levels of technical rigor while maintaining the agility of a startup environment.\nThe successful candidate will also present engineering design review materials to our customers and executive team. As such, excellent written and verbal communication skills are required.\nJOB DUTIES AND RESPONSIBILITIES\nOwn end-to-end design of power converters, and power management and control circuits, from concept and architecture definition to schematic, printed circuit board (PCB) design, testing, qualification, production transition and production support.\nPerform detailed and complete schematic design for low to high complexity power electronics designs , ranging from single power converters to mukti-output power supply modules and power management circuitry.\nPerform detailed PCB layout in Altium Designer independently or in collaboration with a PCB Drafter.\nPerform modeling and analysis of analog and power electronics designs including worst-case circuit analysis, stress analysis, small signal and stability analysis, power loss and efficiency optimization analysis, and power integrity analysis.\nDevelop design verification test plans, requirement compliance matrices, system integration and qualification test plans, and production acceptance test plans for power converters and power supply designs.\nPerform bring-up and design verification testing of power electronics circuits and modules, often working with a technician or junior engineer to complete design verification.\nCollaborate with multi-discipline engineering team and lead system integration and qualification campaigns, and release analog and power electronics designs to production.\nMentor junior engineers to build technical understanding and foster professional development of team.\nPerform research and keep up with new power electronics technology and industry trends to drive innovation and generation of intellectual property.\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONS\nBachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university.\nMinimum of 5 years of industry or university research experience in board-level power electronics design, analysis, and test.\nExperience owning the design phase of power electronics or power subsystems, including power architecture and requirements definition, trade studies, power converter and analog electronics design, component selection, and detailed design.\nExperience performing or guiding complex PCB layout for analog and power electronics.\nExperience with analysis and simulation tools such as SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, or MathCAD\nStrong laboratory testing and troubleshooting experience for prototyping, design verification testing and qualification of analog and power electronics hardware.\nDirect experience designing high-reliability electronics for automotive, space or defense applications, including part derating, worst-case analysis, and thermal constraints.\nExcellent written and verbal communication skills.\nPREFERRED EXPERIENCE\nExperience delivering subcircuit or board designs to production and deployment.\nProficiency in printed circuit board design tools such as Altium, OrCAD/Allegro, PADS/Xpedition, or similar.\nExperience running board-level power integrity simulation tools such as Ansys SiWave, ADS SIPro, or HyperLynx.\nDesign for space radiation environments.","description_format":"text","description_chars":4211,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Professional
