Lead Diagnostic Engineer

Role overview

A lead field engineering role focused on diagnostics, commissioning, and post-installation service for power and distribution transformers serving utility, industrial, and hyperscale data center customers. The position combines hands-on technical work with customer-facing responsibilities, helping establish diagnostic and service capabilities for a scaling transformer product line. Travel is heavy and on-site presence is central to the work.

• Lead on-site installation oversight, commissioning, and startup of oil-filled and dry-type transformers at customer facilities.
• Conduct acceptance and diagnostic testing per IEEE/IEC/NEMA standards, including Turns Ratio, insulation resistance, power factor, SFRA, and Dissolved Gas Analysis sampling.
• Support energization planning, outage coordination, and site readiness reviews alongside customers, EPCs, and project managers.
• Diagnose and troubleshoot On-Load Tap Changers, cooling systems, bushings, and protection interfaces; recommend corrective or preventive actions.
• Produce customer-ready technical reports and feed field observations into failure analysis, warranty investigations, and continuous improvement processes.
• Serve as the primary on-site technical representative, including emergency response with after-hours and weekend support.

• Bachelor's degree in Electrical Engineering or related field, OR equivalent experience such as military electrical training or an associate degree with relevant field work.
• 2+ years of hands-on field experience with power/distribution transformers, switch gear, or related power delivery equipment.
• Working knowledge of transformer diagnostic methods: TTR, insulation resistance, DGA/oil analysis, and power factor testing.
• Ability to interpret electrical schematics, single-line diagrams, and winding/vector diagrams.
• Willingness to travel 50-75%, including domestic and potentially international sites.
• Valid driver's license; ability to maintain or obtain a passport; physical ability to lift equipment and work at heights, in confined spaces, and in outdoor industrial environments.

• Experience with major OEM transformer platforms.
• Familiarity with On-Load Tap Changers, cooling systems (ONAN/ONAF/OFAF), and bushings.
• NETA certification or progress toward NETA Level II/III.
• Protective relay testing and interpretation experience.
• Data center or other mission-critical facility background.

• Subsidized health, dental, and vision insurance.
• Equity options in a rapidly growing startup.
• 401(k) with 4% employer match.
• Unlimited PTO and parental leave.
• Healthcare and Dependent Care FSA or HSA, plus commuter benefits where applicable.
• Heavy travel position with company vehicle or travel allowance, per diem, and standard field service equipment provided.
• On-call rotation for emergency customer support.
