Sustainment Mechanical Engineer

About This Role

The Sustainment Mechanical Engineer is responsible for the ongoing support, improvement, and reliability of released mechanical and electromechanical products throughout their production lifecycle. This role involves owning mechanical design changes for fielded and in-production systems, resolving quality and manufacturing issues, and ensuring product performance, reliability, and compliance are maintained over time. You will apply strong analytical and design skills, including structural FEA, vibration and modal analysis, and heat transfer.

Responsibilities

• Own mechanical sustainment activities for released products across production and fielded units
• Investigate and resolve quality, reliability, and manufacturing issues through structured root-cause analysis
• Develop and implement engineering change orders (ECOs) and product updates while maintaining configuration control
• Perform structural FEA to assess design changes, fatigue, durability, and failure modes
• Conduct vibration and modal analysis to evaluate field failures, resonance issues, and environmental loading
• Perform thermal and heat transfer analysis to support corrective actions and design improvements
• Design and update injection-molded plastic and machined components, ensuring tooling and production readiness
• Support production, suppliers, and contract manufacturers with design clarifications and corrective actions
• Maintain accurate CAD models, drawings, specifications, and GD&T
• Own mechanical document control, including drawings, BOMs, change history, and release status in the PLM system

Requirements

• BS or MS in Mechanical Engineering or related field
• 3+ years’ experience supporting production and fielded mechanical products
• Demonstrated expertise in structural FEA, vibration/modal analysis, and thermal analysis
• Proven experience with injection molding design, tooling changes, and production constraints
• Solid understanding of mechanical failure mechanisms, fatigue, wear, and environmental effects
• Proficiency in SolidWorks, PDM, and PLM systems
• Experience with engineering change management and document/configuration control
• Familiarity with first article inspection (FAI), non-conformance resolution, and corrective action processes
• Ability to work effectively across cross-functional teams and external suppliers
• Strong attention to detail and documentation discipline

Qualifications

• BS or MS in Mechanical Engineering or related field
• 3+ years’ experience supporting production and fielded mechanical products

Nice to Have

• Experience supporting high-volume or regulated manufacturing environments
• Experience with cost-reduction and value engineering initiatives
• Experience supporting products through long-term lifecycle and end-of-life transitions
