Senior Power Electronics Engineer

Senior Power Electronics Engineer

Radiant is seeking a talented senior electrical power engineer to own designs from requirements capture through operation. The candidate will own the architecture of a nuclear microreactor power system capable of outputting 1 MW of electrical power to a grid or microgrid. The ideal candidate should be comfortable jumping from designing high power circuit boards and alternators to testing microgrid power equipment. This role requires collaboration with multi-disciplinary teams for proper operation of a nuclear reactor, fluids system, and structures. No nuclear engineering experience is required.

This role is full-time onsite in El Segundo, CA. 

Responsibilities and Duties:

• Work with multi-disciplinary team to support the architectural design, implementation, and testing of a 1 MW nuclear microreactor electrical control system.
• Responsible Engineer with total ownership over the Kaleidos power system including requirements definition and project management.
• Develop and test high speed alternator, rectifiers, and inverters for 1MW delivery to microgrid through direct design engineering and vendor management to minimize schedule.
• Develop and test DC high power battery to provide black start capability, all power internal to Kaleidos, energy storage to the grid, and stability to the electrical power conversion equipment.
• Create system electrical models for integration into reactor digital twin and microgrid simulations and validate through component and system testing.

Required Qualifications and Skills:

• 6+ years experience designing compact electrical hardware for megawatt power conversion, including alternators, active rectifiers, DC/DC converters, and inverters.
• Design and test experience with 480V AC three-phase microgrids, circuit breakers, load banks, power factor measurement.
• Regulatory familiarity and design experience with islanding, grid-tie, grid-forming.
• Experience working a combined design approach with in-house and vendor to sourcing complex electrical power hardware.
• Experience with cooling system integrated design, liquid cooled architectures.
• Bachelor’s or higher degree in electrical engineering or related field.
• Experience trading electrical architectures and make vs. buy trades.

Desired Qualifications & Skills:

• 8+ years experience with utility scale power systems: transformers, breakers, switchgear, wire and cable systems at 12kV+, and connectorized systems at 1kV.
• Experience designing fault-tolerant and safety critical hardware.
• Experience building teams, interest in mentoring younger engineers.
• Experience using Ethernet, CANbus, RS-422, or other communications protocols.
• Proficiency with electrical cabinet or circuit board design software tools.
• Familiarity with radiation effects on electronics.
• Experience implementing microcontrollers and/or FPGAs.
• Basic familiarity with Python and C/C++.
