The Senior Mechanical Engineer delivers hands‑on engineering support across mechanical design, sustaining engineering, build, test, and production readiness activities. The role owns the execution of moderately complex mechanical work packages, supporting programs through design implementation, troubleshooting, and delivery of practical, technically sound solutions in both development and operational environments. Responsibilities span mechanical design ownership, production support, and environmental and dynamic considerations to ensure robust performance and successful system integration.

• Execute mechanical design and support activities across development, test, and production environments, including part and sub‑assembly design, updates, and release support.
• Provide sustaining engineering for released hardware including investigations, dispositions, design updates, and documentation support.
• Support and develop test fixtures, tooling, and TEQ as needed to enable verification, troubleshooting, and production readiness.
• Investigate build, test, and field issues; perform root‑cause analysis and implement corrective actions.
• Support verification activities including test setup definition, requirements interpretation, execution support, and results documentation.
• Support vibration, shock, and dynamic testing, including shaker test setup definition, fixture considerations, execution support, and results interpretation.
• Apply engineering judgment to address dynamic response, durability, and environmental loading through a combination of analytical understanding and hands‑on test experience.
• Partner with manufacturing and operations on producibility improvements, process robustness, and issue resolution.
• Coordinate with suppliers and vendors for fabrication, modification, and qualification of fixtures, tooling, and test assets.
• Communicate technical findings, options, and recommendations to peers and leadership.

• Degree in STEM (Science, Technology, Engineering or Mathematics) with minimum 5 years of relevant experience, or an advanced degree in a related field with minimum 3 years of experience.
• Experience supporting mechanical design, integration, and release of components and assemblies.
• Demonstrated strength in troubleshooting, failure investigation, and root‑cause identification.
• Working knowledge of vibration, shock, and dynamic behavior, including exposure to test support or environmental qualification activities.
• Hands‑on experience operating in laboratory and production environments, with a practical, solutions‑oriented mindset.
• Ability to translate technical requirements into implementable design, test, and verification solutions.

• Experience with NX CAD and Teamcenter or similar PLM systems, including drawing release processes.
• Background working in lab and test environments, with general instrumentation awareness.
• Exposure to environmental testing methodologies such as sine/random vibration, shock testing, and shaker systems.
• Familiarity with basic structural, thermal, mechanical, or dynamic analysis (hand calculations or FEA exposure).
• Ability to apply sound engineering judgment when evaluating test results and design trade‑offs.
• Experience participating in Root Cause & Corrective Action (RCCA) activities and Failure Review Boards (FRBs).
• Exposure to dynamic analysis techniques or correlation of analytical predictions with test data.

• Medical, dental, and vision insurance
• Three weeks of vacation for newly hired employees
• Generous 401(k) plan with employer matching and lifetime income strategy option
• Tuition reimbursement program
• Student loan repayment program
• Life insurance and disability coverage
• Optional additional coverages (pet, home, auto, accident, critical illness, group legal,  protection)
• Birth, adoption,…
