Overview

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. The Senior Mechanical Engineer is responsible for developing accurate and manufacturable designs for low- to medium-voltage switchgear, ensuring compliance with customer requirements and regulatory standards.

Responsibilities

• Create detailed 3D models and drawings of sheet metal panels, structural supports, barriers, and bus assemblies using CAD software, specifically AutoDesk Inventor.
• Ensure all designs align with manufacturability, customer specifications, safety, and regulatory requirements.
• Collaborate closely with electrical designers to accurately integrate structural and copper bus elements into customer drawing packages.
• Partner cross-functionally with project management, manufacturing, sales, estimating, and field service to support project execution and resolve technical issues.
• Prepare bills of materials, assembly drawings, and cut sheets to support manufacturing in a timely and efficient manner.
• Reduce cycle time by reusing or adapting existing designs where applicable.
• Contribute to design reviews and process improvements that enhance quality, reduce costs, and improve reliability.

Requirements

• 3 to 7 years of progressive mechanical design experience, with significant experience in switchgear, power distribution equipment, or related electrical equipment manufacturing.
• 3+ years of hands-on experience with sheet metal design, structural assemblies, and conductive bus bar design for low- to medium-voltage applications.
• Advanced proficiency with AutoDesk Inventor; familiarity with additional 3D CAD tools a plus.
• Extensive experience preparing parts lists, bills of materials, and assembly drawings for manufacturing.
• Strong knowledge of manufacturing processes, including sheet metal fabrication, machining, press brake operations, and CNC punch equipment.
• Understanding of product lifecycle management, quality control, design for manufacturability, and cost optimization.
• Proven ability to lead complex mechanical design projects and collaborate with cross-functional teams.
• Proficiency with Microsoft Office Suite; experience with ERP/MRP systems such as IFS, SAP, or similar.
• Strong problem-solving and critical-thinking abilities.
• Excellent written and verbal communication skills, with the ability to present complex technical information to customers, leadership, and cross-functional teams.
• Advanced mathematical skills, including the ability to calculate proportions, dimensions, tolerances, and material specifications.
• Highly organized, self-motivated, and detail-oriented with a commitment to quality and integrity.
• Bachelor's degree in Mechanical Engineering, required.
• Professional Engineer (PE) license preferred.

Additional Information

• FLSA executive and professional positions paid on a salary basis, where project requirements and tight client deadlines may require workweeks over forty (40) hours (including weekends or holidays).
• This role will be in office setting, however frequent visits to the production floor are required to oversee operations, ensure compliance and safety standards.
• Mobility: Ability to move around the manufacturing plant, including walking, standing, and climbing stairs.
• Manual Dexterity: Occasional use of hands to handle or feel objects, tools, or controls.
• Lifting: Ability to lift and carry items up to twenty-five (25) pounds. All lifting should be done following OSHA standards.
• Visual and Auditory Requirements: Must be able to see and hear well enough to navigate the plant safely and communicate effectively with team members.
• Frequent travel to regional sites required; presence on production floors is expected.
