Job summary

Leidos is seeking a Senior Power System Engineer for Renewable & Data Center Integration, focusing on large load and data center interconnections within ERCOT. The role emphasizes transmission-level planning, dynamic modeling, and EPC design for utility-scale renewables and hyperscale data centers.

The ideal candidate will have hands-on ETAP/PSSE/PSCAD experience, strong regulatory knowledge, and the ability to interface with TSPs and ISO/RTOs. Remote work is supported with a US-wide context.

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering (Power Systems preferred).
• 8+ years of relevant experience in power systems planning and interconnection.
• Strong experience in PSS/E dynamic modeling and analysis PSCAD EMT modeling.
• Demonstrated experience with large load interconnection studies (data center experience strongly preferred) ERCOT transmission planning and compliance requirements.
• Experience developing dynamic PSSE and PSCAD models for large inverter-based resources and electronic loads.
• Familiarity with NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections.
• Experience embedding and coordinating PPC and MPC control strategies.
• Professional Engineer (PE) license (preferred but not required).

Responsibilities

• Lead and support large load and generation interconnection studies in ERCOT and other transmission systems.
• Apply and interpret NERC, FERC, ISO/RTO, TSP requirements for both generation and large load interconnections.
• Develop and validate steady state models in ETAP and PSSE, and dynamic models in PSS/E and PSCAD for large electronic loads, PV, wind, and BESS resources.
• Support development and integration of Solar/Wind/BESS Power Plant Controllers (PPCs) and Master Plant Controllers (MPCs).
• Participate in EPC HV/MV substation design studies for large data center projects and utility-scale PV/wind/BESS projects.
• Support or lead microgrid design and control studies at MV and HV levels.
• Interface with Transmission Service Providers, ISO/RTOs (especially ERCOT), developers, OEMs, and project stakeholders.
• Perform steady-state and short-circuit analyses including load flow, short circuit, protection coordination, arc-flash, reactive power and energy loss, and harmonic studies.
• Conduct EMT studies in PSCAD including transient overvoltage, TRV, insulation coordination, SSR/SSO screening and mitigation.
