Job Title: Senior Electrical Engineer

Job location: Irvine, CA

Job type: Full-time/ Hybrid

ETAP is seeking a Senior Electrical Engineer with deep expertise in Transmission and Distribution (T&D) Interconnection Studies within the power grid. The successful candidate will lead modeling, simulation, and technical analyses for interconnections involving utility-scale renewable generation, battery energy storage, and conventional generation across both transmission and distribution networks. This role also contributes to the development of next-generation tools that address the growing challenges of renewable integration and grid reliability.

The ideal candidate has extensive hands-on experience leading utility-scale interconnection projects across the U.S., with strong technical judgment, in-depth understanding of ISO/RTO procedures, and a proven track record of delivering high-quality studies and obtaining regulatory approvals.

Key Responsibilities

• 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 (e.g., 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.

Required Qualifications

• Bachelor’s, Master’s, or Ph.D. degree 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 U.S. interconnection standards and procedures, including IEEE 1547, IEEE 2800, NERC/FERC, and ISO/RTO processes (CAISO, PJM, ERCOT, MISO, etc.).

• Proficiency in simulation tools such as PSSE, PSCAD, PSLF, and TSAT, along with familiarity with their associated scripting and automation interfaces (e.g., 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
