Principal, Transmission Electrical Engineering

Apply Description WorldWide Mission Critical is seeking a Director/Principal, Transmission Electrical Engineering to serve as the company's senior in-house technical authority on electric transmission systems supporting hyperscale data center campuses across the United States. This role is responsible for transmission system planning analysis, substation design review, and construction-phase technical oversight across WMCC's development portfolio. The role partners closely with WMCC's Power Interconnection team (who own the utility/TSO/DSO relationship and commercial negotiation) and with internal development and engineering teams to ensure transmission and substation infrastructure is technically sound, standards-compliant, and delivered on schedule. Key Responsibilities Serve as WMCC's senior technical authority on electric transmission engineering, spanning system planning studies (load flow, short circuit, stability) and physical substation design (site layout, protection & control, equipment specification). Review and validate transmission interconnection studies, system impact studies, and facility studies prepared by utilities, ISOs/RTOs, and third-party engineering consultants. Provide technical oversight of substation design packages prepared by EPC firms and engineering consultants, ensuring compliance with NERC, NESC, and IEEE standards and utility-specific design criteria. Support construction-phase technical oversight for transmission lines and substations, high voltage equipment procurement, coordinating with construction management teams, EPCs, and utility construction/inspection personnel. Partner with the Development teams to translate utility-provided technical requirements (queue position studies, connection agreements, protection requirements) into actionable engineering scope. Evaluate the technical risk and schedule impact of transmission/substation constraints, providing clear input to development, commercial, and finance stakeholders. Maintain working knowledge of NERC reliability standards and regional transmission planning criteria (e.g., PJM, MISO, ERCOT, WECC) across WMCC's active development markets. Represent WMCC in technical working sessions with utility/RTO transmission planning and engineering counterparts. Requirements 8+ years of experience in electric transmission engineering at a utility, transmission owner, or engineering/EPC consulting firm, spanning both transmission system planning and substation design and/or construction. Bachelor's degree in Electrical Engineering or a related field. Deep working knowledge of transmission planning studies (load flow, short circuit, stability) and substation design fundamentals (protection & control, equipment specification, physical layout). Direct experience with utility interconnection processes, including queue studies and system impact/facility study review. Familiarity with NERC reliability standards and regional transmission planning criteria in at least one major U.S. market (PJM, MISO, ERCOT, WECC, SPP, or similar). Demonstrated ability to operate as a senior individual technical contributor, translating complex engineering analysis into clear guidance for non-technical stakeholders. Preferred Qualifications Professional Engineer (PE) license. Experience specific to hyperscale data center or other large-load interconnection projects. Experience transitioning from a utility/transmission-owner environment into a large-load developer or EPC environment. Experience with substation construction management or construction-phase technical oversight. Familiarity with flexible/curtailable load or BESS interconnection structures. Core Competencies Transmission system planning & analysis Substation design & engineering standards Utility interconnection process expertise Cross-functional technical communication Independent, senior-level technical judgment Travel & Work Environment Remote/flexible within the United States, with an estimated 15–20% travel to project sites, utility offices, and WMCC development team locations as needed.
