Project Engineer

ON.energy is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers. 

Location: Remote considered / Hybrid in Houston, TX or Tysons, VA preferred

Travel: 20-30% travel to project sites in the US

Overview:

• Support the end-to-end engineering execution of BESS projects for data centers, from development to commissioning.Manage the technical scope of projects and serve as the technical point of contract to the project manager.
• Coordinate with internal engineering, procurement, and construction teams to ensure project milestones are met.
• Collaborate with customers, EPC contractors, OEMs, and design consultants on integration of BESS with data center electrical infrastructure.
• Review and validate system designs (electrical, civil, mechanical) and vendor submittals to ensure technical compliance and quality.
• Design and develop Single line diagrams, Schematics, Wiring diagrams for Battery storage systems
• Prepare Electrical Equipment Specifications, Data Sheets, Purchase Requisitions and Bid evaluations for inverters, Switchgear, Transformers and other electrical equipment as required
• Develop Short circuit, load flow, and arc flash studies using software such as ETAP.
• Assist in developing project schedules, procurement plans, and technical documentation.
• Conduct site walks and support field activities during installation and commissioning.
• Participate in Factory and Site Acceptance Testing (FAT/SAT) of BESS components and systems.
• Identify technical risks and propose mitigation strategies in coordination with Project Management.
• Ensure all work is compliant with relevant codes (e.g., NEC, IEEE, NFPA) and On Energy Storage’s internal standards.

Required Qualifications
