About this role

About the Role ETAP is seeking a Senior Electrical Engineer with deep expertise in Transmission and Distribution Interconnection Studies. You will lead modeling, simulation, and technical analyses for interconnections involving utility-scale renewable generation, battery energy storage, and conventional generation across transmission and distribution networks. You will contribute to next-generation tools addressing renewable integration and grid reliability to support safe, reliable energy transitions.

What You'll Do

  • Develop and validate detailed models for renewable generation, battery storage, and distributed resources.
  • Lead and perform interconnection studies for both transmission and distribution systems, including: Power flow and voltage profile analysis; Short-circuit and protection coordination; Dynamic and transient stability studies; Harmonic and power quality studies.
  • Conduct studies using and cross-verifying results from multiple software platforms such as ETAP, PSSE, PSCAD, PSLF and TSAT.
  • Coordinate with utilities, ISOs/RTOs, and developers to ensure compliance with U.S. interconnection requirements (FERC, NERC, IEEE, state utility standards).
  • Prepare comprehensive study reports, technical memoranda, and client presentations summarizing results and recommendations.
  • Supervise and mentor study engineers, ensuring consistency and quality of results across projects.
  • Provide technical leadership in developing study methodologies, automation tools, and best practices for U.S. T&D interconnection studies.
  • Research, design, and test software applications for modeling, control, and energy management of renewable energy systems.
  • Collaborate with internal teams and customers to support regulatory approvals and project delivery.

What We're Looking For

  • Bachelor’s, Master’s, or Ph.D. in Electrical Engineering (Power Systems emphasis preferred).
  • 5+ years of professional experience conducting and leading transmission and/or distribution interconnection studies for utility-scale projects.
  • Strong working knowledge of IEEE 1547, IEEE 2800, NERC/FERC, and ISO/RTO processes (CAISO, PJM, ERCOT, MISO, etc.).
  • Proficiency in PSSE, PSCAD, PSLF, and TSAT, along with scripting interfaces (Python, PSS/E API, PSLF EPCL, PSCAD scripting).
  • Expertise in modeling and control of renewable plants, battery storage, and inverter-based resources.
  • Excellent written and verbal communication skills with the ability to clearly explain complex technical results to diverse audiences.
  • Demonstrated ability to manage multiple projects and lead cross-functional engineering teams.
  • Work Authorization: U.S. Citizenship or permanent residency/work authorization.
  • Strong coordination with utilities/ISOs/RTOs.

Nice to Have

  • Power Systems emphasis in degree (MS/PhD preferred).
