Company:

While public company competitors answer to shareholders, this company answers to innovation. As a privately-owned company, they reinvest 3.5% of profits back into this R&D department. With data center development exploding, they are projecting to double their revenue in the coming years, and growing their engineering team accordingly.

Role:

  • Lead NPD projects for MV (5kV - 38kV) and HV switchgear (>38kV), reclosers, and fault-protection systems.
  • Design new high-accuracy current and voltage sensors for power grid automation systems.
  • Hands-on test plan creation and execution in the on-site high-voltage lab.
  • Drive product design decisions that impact critical electric infrastructure.

What We’re Looking For

  • 5+ years of experience in MV or HV power systems design (>1kV)
  • Strong grasp of IEEE/NEC standards and a passion for electrical power systems
  • A Bachelor’s in Mechanical Engineering (BSME) is required.
  • You come from an OEM background or a utility substation design environment

The Perks

  • Family-Owned Culture: Extended holiday shutdowns and a "take care of our own" mentality.
