• Apply and enforce applicable codes and standards (NEC, NFPA 70E, IEEE, and local jurisdictional requirements) in all design work, escalating conflicts or ambiguities to the Lead Electrical Engineer.
• Participate in interdisciplinary design reviews, 3D model reviews, and safety‑in‑design/HAZOP reviews as required, representing the electrical discipline's design intent.
• Comply with all Company and HSE procedures and policies.
• Follow Corporate Principles:
• Professionalism - Professional in everything we do
• Integrity - Integrity above all
• Teamwork - One Team. One Spirit. One Goal.

Required Skills:

• Proficiency in AutoCAD and/or Revit and other electrical design software; familiarity with 3D modeling/BIM coordination platforms preferred.
• Working knowledge of NEC, NFPA 70E, IEEE, and other applicable electrical design codes and standards.
• Strong technical aptitude in electrical power distribution, grounding, lighting, and instrumentation interface design.
• Ability to read and interpret one-line diagrams, P&IDs, specifications, and vendor data for electrical design coordination.
• Strong attention to detail and disciplined quality‑checking of own and others' work.
• Effective written and verbal communication skills for interdisciplinary coordination and technical reporting.
• Ability to mentor junior staff and to work with minimal supervision on complex design tasks.

Education and Experience:

• Associate's degree or technical certificate in drafting/design, or equivalent CAD/design training; B.S. in Engineering Technology or related field preferred.
