• Develop and implement mechanical design improvements focused on quality, reliability, manufacturability, serviceability, and performance.
• Drive cost reduction initiatives through design optimization, material substitutions, component standardization, and manufacturing improvements.
• Identify, evaluate, and qualify second-source suppliers and components to improve supply chain resiliency and reduce sourcing risks.
• Support Design for Manufacturing (DFM) and Design for Assembly (DFA) initiatives to improve product quality and manufacturing efficiency.
• Create and modify 3D CAD models, assemblies, and engineering drawings in SolidWorks.
• Generate and maintain engineering documentation, engineering change orders, part releases, and BOM updates.
• Apply GD&T principles to component and assembly drawings.
• Support sustainment of enclosure systems, ventilation systems, structural assemblies, plumbing systems, and mechanical component integration.
• Coordinate and execute testing activities to validate design changes, alternate-source components, corrective actions, and product improvements.
• Work closely with Manufacturing, Quality, Reliability, Supply Chain, Service, and Product Development teams to implement engineering solutions.
• Support supplier interactions related to technical issues, component qualification, manufacturability improvements, and cost reduction opportunities.
• Manage multiple concurrent engineering projects and sustainment activities while meeting project schedules and business objectives.
• Participate in review and disposition of engineering changes and configuration management activities.

• Bachelor's degree in Mechanical Engineering or related engineering discipline.
• 5+ years of mechanical engineering experience in sustaining engineering, product development, manufacturing engineering, or related fields.
• Experience with root cause analysis and corrective action implementation.
• Familiarity with 8D methodology and structured problem-solving approaches.
• Proficiency with 3D CAD software, preferably SolidWorks.
• Experience creating and modifying engineering drawings with GD&T.
• Experience supporting engineering change management, BOM structures, and product documentation.
• Strong mechanical design fundamentals and engineering judgment.
• Excellent organizational skills with the ability to manage multiple projects and priorities simultaneously.
• Strong written and verbal communication skills.
• Self-motivated with the ability to work independently and drive assignments to completion.

• Experience with industrial equipment, energy systems, process equipment, or complex electromechanical products.
• Experience with plumbing systems including tubing, valves, fittings, manifolds, and fluid routing.
• Experience with enclosure systems, environmental sealing, doors, ventilation systems, and outdoor equipment.
• Experience with sheet metal fabrication, weldments, structural assemblies, and associated manufacturing processes.
• Experience supporting mechanical testing and validation activities.
• Experience with supplier qualification, alternate-source development, and component validation.
• Familiarity with DFM, DFA, DFMEA, PFMEA, and reliability engineering principles.
• Hands-on experience troubleshooting mechanical systems and assemblies.
