About The Position

The Senior Mechanical Engineer develops accurate, manufacturable designs of sheet metal panels, structural supports, barriers, and conductive copper bus assemblies for low- to medium-voltage switchgear. The role ensures designs meet customer requirements, regulatory standards, safety expectations, and manufacturing best practices while supporting efficiency, quality, and company growth. The engineer collaborates with electrical designers, engineers, project managers, manufacturing personnel, and other cross-functional partners, and serves as a key resource for resolving complex design challenges.

The position primarily works in an office setting, with periodic visits to Mission Critical Group manufacturing locations and supplier facilities to assess capabilities, support sourcing initiatives, address performance issues, and engage cross-functional teams. Workweeks may exceed 40 hours, including weekends or holidays, when project requirements and client deadlines require it. The job also involves mobility around manufacturing plants, including walking, standing, and climbing stairs; occasional handling of objects, tools, or controls; and lifting and carrying items up to 25 pounds in accordance with OSHA standards. The employee must be able to see and hear sufficiently to navigate plants safely and communicate effectively.

Requirements

• At least 7 years of progressive mechanical design experience, including significant experience in switchgear, power distribution equipment, or related electrical equipment manufacturing.
• At least 5 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.
• 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 and experience with ERP/MRP systems such as IFS, SAP, or similar.
• Strong problem-solving and critical-thinking abilities.
