  • Power and control wiring diagrams
  • Instrumentation loops
  • Electrical schematics
  • Cable tray layouts
  • Electrical and instrumentation details
  • Cable schedules
• Produce accurate 2D/3D AutoCAD drawings based on field findings and engineering direction.
• Ensure drawings comply with internal standards, safety requirements, and industry codes.

Field Work & Data Collection

• Conduct on‑site field visits to gather measurements, verify existing installations, and collect data needed for new or updated designs.
• Document field conditions thoroughly (measurements, equipment labeling, routing information, site photos) and translate findings into updated engineering drawings.
• Interface with plant personnel when needed to clarify equipment access, layouts, and existing electrical infrastructure.

Electrical System Expertise

• Demonstrate strong understanding of electrical power distribution systems.
• Perform sizing and selection of circuit breakers and other protective devices as required for design packages.
• Read, interpret, and update one‑line diagrams, panel schedules, and equipment lists.

Collaboration & Project Support

• Work with project teams, including designers and engineers, throughout the design and review process.
• Support design reviews by providing drawing updates, design clarifications, and field verification as needed.
• Maintain organized documentation and revision control across multiple projects.

Qualifications

• 7+ years of CAD design/drafting experience, preferably with a focus on electrical power and control systems.
• Expert‑level AutoCAD experience required; strong ability to create and modify complex electrical drawings.
• Deep knowledge of electrical design principles, including breaker sizing, load calculations, and power distribution layouts.
• Experience conducting field measurements and developing designs based on real world data.
• Ability to collaborate with engineers, designers, and plant personnel.
• Strong attention to detail, accuracy, and documentation practices.

Travel & Work Environment

• Estimated travel: ~25%, primarily for field visits.
• Driving required only for sporadic site visits; most work is local to Chesterfield.
• When travel is needed, leased fleet vehicles are available.
