• 2+ years of hands-on field experience with power/distribution transformers, switchgear, or related power delivery equipment (entry-level candidates with strong internships/training programs will be considered)
• Working knowledge of transformer testing: TTR, insulation resistance, DGA/oil analysis, power factor testing
• Ability to read and interpret electrical schematics, single-line diagrams, and winding/vector diagrams
• Willingness and ability to travel 50–75%, including domestic and potentially international sites
• Valid driver's license; ability to maintain/obtain a passport
• Physical ability to lift/move equipment components and work in industrial field environments (heights, confined spaces, outdoor conditions)

Bonus Points

• Experience with OEM transformer platforms (ABB, Siemens, GE, Hitachi Energy, Powell, ERMCO) or equivalent
• Familiarity with On-Load Tap Changers (OLTC), cooling systems (ONAN/ONAF/OFAF), and bushings
• NETA certification or working toward NETA Level II/III
• Experience with protective relay testing and interpretation
• Data center or mission-critical facility experience
• Prior experience at a transformer OEM, utility, or independent testing/service organization
