High Voltage Power Engineer

About This Role

As part of Intersect’s Engineering team, you’ll lead the design, coordination, and technical oversight of high-voltage (HV) and medium-voltage (MV) systems across solar, wind, and battery storage projects. You’ll drive utility interconnection, optimize substation and transmission designs, and support projects from early development through financing, construction, and commissioning. Beyond project delivery, you’ll also provide ongoing technical support to Operations, ensuring assets perform reliably throughout their lifecycle. This is a highly cross-functional role, requiring close collaboration with Development, Permitting, Construction, Finance, Operations, and external EPCs, utilities, and consultants.

Team Overview

The Engineering team ensures Intersect’s energy projects are technically sound, cost-optimized, and built for long-term reliability. We develop standards, review designs, and coordinate across functions to bring complex clean energy facilities online at scale. By bridging technical expertise with project execution, we help Intersect accelerate deployment while meeting the highest safety, quality, and performance standards. Joining this team means shaping the backbone of our power infrastructure and driving the interconnection of next-generation energy projects.

What You’ll Do

Lead HV & MV Design

• Develop and review preliminary HV transmission and substation designs, as well as MV distribution designs and single-line diagrams

• Collaborate with EPCs, engineers of record, and external consultants to optimize facility design and execution

• Maintain and improve internal design tools for engineering analysis and calculation

Drive Utility Interconnection

• Participate in recurring meetings with utilities to advance interconnection discussions from development through commissioning

• Support preparation and review of interconnection applications and dynamic models to ensure accuracy and compliance

• Serve as a technical lead for Independent Engineer (IE) diligence and project financing reviews

Build Standards & Technical Excellence

• Develop and maintain technical specifications, design criteria, standards, and EPC technical exhibits

• Review vendor specifications, testing protocols, and commercial agreements to ensure alignment with project requirements and cost optimization

• Support EPC RFPs to ensure technical requirements are clearly defined and competitive

Cross-Functional Collaboration

• Work with Development, Land, Permitting, Construction, and Operations teams to ensure seamless project delivery

• Resolve regulatory, permitting, and technical challenges with a focus on cost, schedule, and quality

• Champion high standards of safety, environmental stewardship, and constructability across all engineering activities

What You’ll Bring

• 8-10 years total, including >=4 years in clean energy project development (interconnection, owner’s engineering/IE oversight, EPC management, commercial negotiations) and >=4 years leading HV substation/collector design (345-500 kV) at a developer, IE/OE, or EPC, delivered ≥3 utility-scale projects through energization; led cross-functional teams and external consultants/contractors.

• Strong understanding of HV transmission, substation equipment, MV distribution, metering, relaying, and SCADA/plant controllers

• Technical expertise in power system design, optimization, and studies

• Experience managing interconnection study processes in ERCOT and CAISO, with the ability to review and challenge study results

• Advanced knowledge of steady-state modeling tools such as ETAP, SKP, or DigSILENT

• Hands-on experience collaborating with EPCs and utilities during design and construction phases

• Strong organizational and project management skills, with the ability to drive multiple projects in parallel

• Solid Excel skills and familiarity with system design trade-offs, cost drivers, and construction challenges

• Experience creating specifications and designs for HV transmission and substation equipment, or managing contracting/construction of HV facilities

• Successfully advanced 5+ projects through CAISO, ERCOT, or SPP interconnection processes, ideally across multiple markets and through implementation (pre-EPC through COD)

• Proven ability to lead preparation and review of interconnection applications and dynamic models for utility-scale projects
