at Electric Power Engineers

🏢 About Electric Power Engineers

Electric Power Engineers (EPE) is a specialized consulting firm focused on designing the grid of the future, with a strong emphasis on reliability and resiliency. They are leaders in interconnection and transmission planning, particularly in MISO, SPP, and SERC regions, offering a collaborative environment where senior engineers directly influence growth strategy and mentor junior staff.

About This Role

As Principal Power System Engineer - Interconnection, you will lead complex interconnection studies (load flow, short circuit, transient stability) for clients across Eastern Interconnect ISOs. This role is critical in helping generation, load, and transmission developers navigate interconnection processes while shaping EPE's technical direction and client relationships.

💡 A Day in the Life

Your day might start with reviewing a client's interconnection study results from an ISO, then leading a team meeting to replicate findings and brainstorm alternative mitigations. Afternoon could involve a client call to discuss study outcomes and next steps, followed by mentoring a junior engineer on transient stability analysis. You'll also allocate time to research regulatory updates and contribute to business development proposals.

⚠️ Common Mistakes to Avoid

  • Don't focus on distribution-level work; this role is strictly transmission and interconnection.
  • Avoid generic statements about 'power systems' without specifying interconnection or transmission planning.
  • Don't overlook the regional requirement; emphasizing experience in CAISO or ERCOT without Eastern Interconnect may hurt your application.
