Senior Electrical Engineer - Substation Design

Overview

We are designing the grid of the future! 

EPE is seeking a Senior Electrical Engineer - Substation Design (P.E. required) to lead the engineering and design of medium- and high-voltage substations ranging from 34.5 kV through 345 kV and higher. This role will support our Owner's Engineering group, with a primary emphasis on physical substation design and the delivery of complete engineering packages from conceptual design through Issued for Construction (IFC). The ideal candidate will bring experience leading both greenfield and brownfield substation projects, with a strong understanding of physical design and exposure to Testing & Commissioning (T&C), as well as protection and control (P&C) design.

Our projects include utility-scale solar PV, battery energy storage systems (BESS), wind and hybrid collector substations, point-of-interconnection switching stations, and large-load interconnections supporting data centers and industrial customers across ERCOT and other U.S. markets. As a technical lead, you will guide engineers and designers, review and verify engineering deliverables, and collaborate directly with clients, transmission owners, and EPC contractors to deliver high-quality substation solutions.

Responsibilities

How you can make an impact:

• Lead design from concept to IFC: Own the technical scope, quality and schedule of substation design packages through conceptual, 30%, 60%, 90% and IFC milestones. 

• Physical design: Develop and check general arrangements, plan and section drawings, electrical clearances and phase spacing, rigid and strain bus design, equipment and structure layouts, ground grid design (IEEE 80), lightning shielding (IEEE 998), raceway (conduit, cable trench, duct bank), lighting and bills of material. 

• P&C design: Develop and check one-line and three-line diagrams, AC and DC schematics, wiring diagrams, relay and control panel layouts, and cable schedules. Apply protection schemes for lines, transformers, buses, breakers and capacitor banks, including line current differential, distance, transformer and bus differential, breaker failure, and communication-assisted tripping (POTT, DTT). 

• Brownfield expansions: Lead field verification and reviews of existing conditions, integrate new bays, line terminals and P&C into energized substations, and develop outage, cutover and construction sequencing with the utility. 

• Utility and market interface: Apply transmission owner design standards and interconnection requirements (ERCOT, PJM, MISO, NYISO and other ISOs/RTOs), and support coordination on metering, telemetry and SCADA/communications. 

• Equipment and vendors: Write technical specifications and evaluate vendor proposals and drawings for power transformers, circuit breakers, switches, instrument transformers, relay panels, control enclosures, station service and DC systems. 

• Design reviews: Review EPC and third-party substation and collection system design packages, and provide clear, actionable comments to clients, both on EPE design projects and on owner's engineering assignments. 

• Proposals and estimating: Support scope development, engineering hour estimates and conceptual cost estimates for new work. 

• Mentoring and QA/QC: Mentor engineers and designers, check their work, and uphold EPE quality standards. Seal drawings as engineer of record where licensed. 

• Coordination and construction support: Coordinate with civil/structural, transmission line, system studies and communications/SCADA teams. Submit and  respond to RFIs, and support construction and commissioning. 

• Deliver assigned projects on time while meeting project quality and budget objectives. 

Qualifications

Bring your passion, here's what’s needed:

• Bachelor of Science degree in Electrical Engineering or a related discipline, with a minimum of six years of high-voltage and MV substation design experience with a utility, consulting firm or EPC. 

• Professional Engineer (PE) license (required). 

• Proven experience delivering complete substation design packages from conceptual to IFC, covering both physical and P&C design, at voltages from 34.5 kV to 345 kV or higher. 

• Experience with both greenfield substations and brownfield modifications to existing, energized facilities. 

• Working knowledge of NESC, NFPA, IEEE  and utility/transmission owner design standards, and of how NERC requirements apply to substation design. 

• Solid understanding of protection philosophy and protective relays (SEL, GE, Siemens or similar), plus substation communications, SCADA/RTU and revenue metering. 

• Experience with AutoCAD and grounding analysis software (CDEGS, WinIGS or similar). 

• Strong communication skills and comfort working directly with clients and contractors. 
• Occasional travel to project sites for walkdowns, filed verification and construction support.
