Senior Power Electronics Engineer

The role

This person will own the high-power electrical architecture of the plant. They will define the common DC bus architecture, lead supplier selection, and drive the electrical development roadmap.

What you will do

• Define the common DC bus architecture including voltage levels, topology, and protection.
• Define the expansion architecture for scaling from a single unit to a multi-reactor plant.
• Verify high voltage system integration across different vendor components.
• Implement HV system functions like battery management, bus precharge, and grid-forming operation.
• Manage fault behavior for load drop, short circuits, and converter faults.
• Build and own the high power distribution test system at Antares HQ.
• Turn test results into design decisions through model correlation.
• Manage technical relationships with power electronics suppliers.
• Drive the electrical development roadmap and technology selection.
• Optimize equipment pad layout for cable routing, EMI, and thermal management.

Required qualifications

• Bachelor's degree in Electrical Engineering or a related field
• 5+ years in power electronics or high power electrical systems
• Ownership of a system architecture through hardware bring-up
• Direct experience with DC bus architectures, protection, coordination, grounding and isolation, and fault current analysis
• Hands-on experience with grid-tied inverters, DC/DC conversion, and battery energy storage integration
• Experience with motor drive or generator inverter systems
• Experience with EMI/EMC testing at the product level
• Experience specifying, evaluating, and managing power electronics suppliers
• Experience planning, leading, and executing high-power electrical test campaigns
• Working knowledge of codes and standards such as NEC, NFPA, UL, IEEE, or IEC

Nice to have

• Experience developing or deploying grid-forming control strategies
• Familiarity with IEEE 2800 and evolving interconnection requirements
• Experience scaling a power architecture across multiple paralleled units
• System modeling and study experience using PLECS, PSCAD, Simulink/Simscape, ETAP, SKM, or EasyPower
• Experience with EMI/EMC design for high-dv/dt power electronics
• Experience delivering equipment under a formal quality program (NQA-1, 10 CFR 50 Appendix B, AS9100, IEC 61508)
• Experience building test infrastructure from scratch
• Experience in utility scale energy storage, marine, traction, or aerospace electrification
