Senior Project Engineer

Mission

TAR's mission is to power intelligence for the world. We are building the world's first off-grid power plant for data centers powered by renewable technologies.

We firmly believe AI should be built in the US for the benefit of all people. For that, power must be fast, clean and scalable. We are singularly focused on delivering GW-scale power faster than anyone has ever done, by rethinking every layer of the stack.

To deliver on this vision, TAR manufactures, deploys and operates off-grid energy assets with a renewable backbone. We vertically integrate to solve every bottleneck, from racking systems to power electronics to dispatch algorithms to on-site construction.

Leave your mark by powering the future of civilisation‑scale energy infrastructure.

We hire people who care deeply about this problem space. If that is you, please apply!

Company

We are a team of seasoned operators run by founders who previously scaled a company to over 80 people and $350M in annual sales. We know how to operate and we move fast.

We are working directly with one of the largest compute providers to make our vision come true and plan to deploy 5GWs by 2028.

TAR is both a hardware and software company; we are building out massive, critical, physical infrastructure.

We operate on…

• High ownership. High Agency. Own project end-to-end. Great people don't need to be managed.
• Speed. We achieve great things on incredible timelines. We always push ourselves to go faster.
• First principles. No ego. No hierarchy. Challenge every assumption.
• Passion. Solving the energy problem is one of the largest challenges that faces the world now and in the future. We put in long hours and hard work to solve this.

About the role

TAR builds fully islanded, behind-the-meter microgrids (solar, BESS, and gas peakers) powering AI data centers in West Texas at record speed. As Senior Project Engineer, you own the technical execution of our deployments in the field. You take the design from the engineering team and drive it through procurement coordination, construction, commissioning, and energization to commercial operation. You are the owner‑side technical authority on site, interfacing the Engineer of Record, the EPC, and OEM vendors, and holding scope, schedule, and quality. You report to the Project Director and own the answer to whether the plant is getting built right, and on time.

This is the execution seat. The engineering team sets the design and control architecture; you make it real on the ground, under aggressive timelines, on a continuous high-density IT load with no utility behind it.

Responsibilities

• Own the technical execution of the deployment from issued‑for‑construction through commissioning and commercial operation.
• Drive the islanded commissioning and energization sequence (BESS‑first grid‑forming bring‑up, FAT/SAT, site energization, acceptance testing) with the engineering team and OEMs.
• Manage and hold the Engineer of Record and EPC to scope, schedule, and quality; review EPC contracts, equipment specs, studies, and IFC drawings.
• Coordinate procurement logistics and on‑site sequencing across inverter skids, BESS, MV switchgear, and balance of plant.
• Track and recover schedule against COD; surface risk early and drive it to resolution.
• Run field troubleshooting and bring‑up at the pilot and across the program.
• Enforce site safety and quality throughout construction and commissioning.

Qualifications

• BS in electrical, mechanical, or related engineering, or equivalent field experience.
• 7+ years delivering utility‑scale solar, BESS, power‑generation, or large infrastructure projects.
• Hands‑on ownership of construction and commissioning through COD on at least one project.
• Able to read and hold parties to EPC contracts, equipment specs, study reports, and IFC drawings.
• Understanding of NEC, NESC, IEEE and NFPA standards as they relate to PV, BESS and MV/HV engineering.
• Exposure to MV and HV substation engineering.
• Strong schedule, scope, and milestone management under aggressive timelines.
• Willing to be on‑site in West Texas as deployments require.
• Extreme attention to detail with a bias for speed and rapid iteration.

Nice To Have

• Direct solar+BESS or microgrid commissioning experience.
• Islanded, off‑grid, or BTM experience.
• ERCOT / Texas project experience.
• Owner's‑side experience managing an EOR/EPC as agent.
• Familiarity with grid‑forming BESS bring‑up and protection under islanded conditions.
• Test‑like‑you‑fly culture (Tesla Energy, SpaceX, or comparable).

Salary and Benefits

• Up to $15K relocation bonus
• Unlimited PTO
• Health, Dental, Vision insurance
• $1K monthly stipend for meals
