• Ability to manage multiple projects and prioritize tasks effectively in a fast‑paced environment.
• Familiarity with medium voltage switch gear, utility systems, or the power industry is preferred.
• Exposure to sheet metal design is preferred.
• Strong attention to detail, critical thinking, and problem‑solving abilities.
• Proficiency with Solid Works, AutoCAD, or Pro E;
  Finite Element Analysis (FEA) experience is a plus.
• Knowledge of IEEE/ANSI C37.20 and UL891/1558 design guidelines and NFPA
  70E are desirable.
• Strong verbal and written communication skills.

The salary range for this role is $86,000 -$100,000 (Level II) or $91,200-$130,000 (Level III) per year, based on location, experience, and qualifications.
