Electrical Designer - Modular Buildings

About the role

Mission Critical Group (MCG) is an end-to-end power systems and solutions provider that accelerates time-to-power and delivers scalable, resilient infrastructure for mission-critical environments. By integrating engineering, manufacturing, modular deployment, and lifecycle services under one platform, we streamline execution and bring complex projects online faster—without compromising performance. The Electrical Designer translates customer electrical one-line diagrams into physical, safe, and code-compliant installations within custom modular PDC buildings, mapping the internal layout and power distribution containment infrastructure.

Responsibilities

• Design physical floor plans and clearances for high-voltage switchgear, motor control centers (MCCs), variable frequency drives (VFDs), and Uninterruptible Power Supplies (UPS).
• Route 3D overhead or under-floor cable trays, wireways, and conduit runs ensuring zero interference with the building’s structural steel or HVAC ducting.
• Generate comprehensive terminal-to-terminal interconnection wiring diagrams, interior/exterior building lighting layouts, and structural grounding grid designs.
• Verify all electrical designs adhere strictly to the National Electrical Code (NEC).
• Provide immediate support to industrial electricians on the plant assembly floor.

Requirements

• Associate degree or higher in Electrical Engineering Technology, Electrical Drafting, or a related discipline.
• 3+ years of experience creating physical layouts and electrical schemas for industrial control systems or power distribution equipment.
• Thorough, working knowledge of the National Electrical Code (NEC) clearance and spacing mandates.

Preferred Qualifications

• Experience designing inside modular utility substations, power generation skids, or industrial PDC environments.
• Proficiency using specialized 3D electrical routing software modules within AutoCAD or Revit.

Success Measures

• Complete compliance with NEC standards across all physical equipment and conduit designs.
• Minimization of spatial interference or layout clashes between electrical infrastructure and structural systems.
• Speed and precision in delivering final interconnection wiring schedules to the production floor.

Physical Requirements

• Prolonged periods of sitting at a desk working on advanced design monitors.
• Regular walkthroughs of the assembly shop to audit equipment layouts and electrical integration.
• Ability to perceive colors accurately to verify complex electrical wiring schemas.
