The role

You will develop the medium-voltage electrical system for a 13 MW aeroderivative generator. You will set architecture, run studies, specify equipment, and lead validation and commissioning.

What you will do

  • Translate product requirements into electrical specifications, one-line diagrams, schematics, and BOMs
  • Own the electrical architecture and design of the plant including transformers, switchgear, cabling, protection, and grounding
  • Perform and review power system studies- load flow, short-circuit, protection coordination, arc flash, grounding, harmonics, and transient analysis
  • Ensure compliance with NEC, IEEE, IEC, UL, NFPA 70E, and utility interconnection requirements
  • Own electrical safety and certification for the product
  • Mentor engineers, review designs, and serve as the technical interface to customers, utilities, and suppliers

Required qualifications

  • BS, MS, or PhD with a focus on electrical engineering
  • 10+ years of experience designing, building, testing, and shipping electrical power systems
  • Deep experience with medium-voltage systems (1–38 kV): generators, transformers, switchgear, protective relays, and paralleling/grid-interconnect schemes
  • Strong command of power system analysis (symmetrical components, fault calculations, protection coordination, arc flash) and proficiency in ETAP, SKM, or EasyPower
  • Working knowledge of applicable codes and standards (NEC, IEEE, IEC, UL, NFPA 70E) and experience taking a product through certification
  • Hands-on field experience commissioning and troubleshooting MV equipment and generator control systems
  • Track record of owning a complex electrical product from concept through production with cross-functional teams

Nice to have

  • Familiarity with power electronics (inverters, rectifiers, excitation systems) and controls integration (SCADA, PLC, communication protocols)

Benefits

  • Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
  • 401(k) program
  • transparent stock option plan
  • Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time
