About the role

The Senior Mechanical Engineer – Machine Design / Equipment Design will take ownership of mechanical equipment and system design, from concept through production and implementation. This role requires deep experience (15+ years) in machine design, equipment layout, structural/mechanical details, manufacturing integration, and cross-functional leadership. You will be instrumental in designing, specifying, and delivering major mechanical systems within a high-reliability, safety-driven environment. 

What you'll do

• Lead the mechanical design of machinery, equipment systems, and major assemblies: concept generation, detailed design, integration with manufacturing and installation. 

• Develop layouts, 3D models, assemblies, and detail drawings using advanced CAD/PLM tools; generate equipment specifications and bills of materials. 

• Collaborate with manufacturing, procurement, installation, commissioning, and test teams to ensure designs are manufacturable, installable, maintainable, and meet performance goals. 

• Perform mechanical design trade-studies (materials, fabrication methods, cost, reliability, maintainability) and lead design reviews. 

• Ensure equipment designs comply with applicable codes, standards, safety regulations, materials and fabrication requirements (e.g., pressure boundaries, structural members, welding, dynamic loads). 

• Mentor and lead junior engineers and designers. 

• Provide technical leadership in equipment design for modular and factory-based manufacturing of major mechanical systems. 

Qualifications

• Bachelor’s in Mechanical Engineering (or closely related discipline). 

• 15+ years of mechanical equipment / machine design experience, ideally in high-reliability industrial, manufacturing, or energy sectors. 

• Proven track record designing large mechanical systems, equipment, or heavy machinery. 

• Expertise in CAD/PLM tools (e.g., Siemens NX, SolidWorks, CATIA, Creo) with strong capability in 3D modeling, assemblies, and drawing generation. 

• Strong understanding of mechanical design for manufacturability, materials selection, welding/fabrication methods, installation/maintenance considerations. 

• Excellent communication, collaboration and leadership skills; ability to interact across functions (manufacturing, procurement, commissioning, testing). 

• Comfortable in a dynamic, rapid-growth environment, and able to lead design efforts under schedule and budget constraints

Preferred Qualifications 

• Experience in modular/factory-based manufacturing environments (e.g., skid-mounted systems, modular equipment builds). 

• Prior involvement in the nuclear, power, or heavy-industrial sectors. 

• Familiarity with regulatory/licensing environment for energy equipment. 

• Experience with heavy equipment installation, commissioning and field validation.
