Microgrid Field Engineer

Solaris Energy Infrastructure, Inc. (NYSE:SEI) delivers comprehensive power infrastructure solutions including generation, distribution, installation and commissioning, aftermarket support, and operations and maintenance. Headquartered in Houston, Texas, the Company serves multiple U.S. end markets, including data centers, energy, and other commercial and industrial sectors.

About the Opportunity

At Solaris, you'll design, build, commission, and maintain the power generation, transmission, and distribution systems behind mission-critical data center power for hyperscale and AI infrastructure customers. As a Microgrid Field Engineer, you'll travel to customer sites nationwide to troubleshoot complex electrical systems, commission new equipment, and serve as the face of our team on-site. We're looking for a self-starter with a total ownership mentality — someone early in their career who wants to learn fast and dig into hard technical problems.

This is a travel-intensive, field-based role: you should be based in the continental U.S., within about a two-hour drive of a major airport, and ready to travel extensively to support projects nationwide.

Essential Functions

• Travel to customer sites nationwide to commission, troubleshoot, and maintain electrical power systems and microgrids — including installing and testing relays and protection settings — often working independently under tight timelines.
• Serve as an on-site technical point of contact for customers and operations teams, diagnosing and resolving complex electrical issues with sharp attention to detail.
• Develop, program, test, and troubleshoot protective relay settings and schemes for high-voltage equipment, including relays from SEL, GE, Siemens, and Beckwith.
• Support factory testing (FAT) of purchased and manufactured equipment, including E-houses, switch gear, and gas turbine packages from OEMs such as Solar Turbines, GE, and Pratt & Whitney.
• Champion a safety-first, quality-first mindset on every site visit, ensuring compliance with NFPA 70, 70B, 70E, NESC, and IEEE standards.
• Collaborate with cross-functional engineering teams to drive rapid, continuous improvements and support infrastructure upgrades across project sites.
• Create and maintain power budgets, monitoring, and metering for mission-critical assets to optimize visibility and efficiency.
• Perform detailed design and review of electrical power systems: one-lines, three-lines, control/relaying schematics, wiring diagrams, SCADA, conduit/cable sizing/routing, grounding design, general arrangement, etc.
• Participate in design meetings and reviews for new microgrid and power delivery projects, and support vendor qualification and quality checks on purchased equipment.
• Maintain organized design and asset documentation across all project sites.

Experience/Education

Required

• Bachelor's degree in electrical engineering, computer engineering, physics, or another engineering discipline is desired; equivalent experience may be considered in lieu of a degree.
• 0-2 years of experience in power systems design, analysis, testing, and/or field service, with a focus on high-power, high-voltage systems. Recent graduates with relevant internship or co-op experience are encouraged to apply.
• Willingness and ability to travel extensively (75%+) to customer sites across the continental U.S., often on short notice.
• Must reside in the continental U.S., within approximately a two-hour drive of a major airport.

Preferred

• Hands‑on experience with switch gear, protective relays, or gas turbines (Solar Turbines, GE, Pratt & Whitney) is a huge plus.
• Experience with transformer or switch gear testing, maintenance, or commissioning.
• 3+ years of professional experience in a similar field or…
