This role supports the full product lifecycle from concept through production and ensures designs meet technical, quality, and regulatory requirements. The Senior Mechanical Engineer collaborates cross-functionally, mentors junior engineers, and contributes to continuous improvement and innovation initiatives.

Essential Duties and Responsibilities:

• Lead mechanical design of systems, assemblies, and components using CAD software (SolidWorks, CATIA, or similar).
• Perform structural, thermal, vibration, and stress analyses using FEA and other engineering tools.
• Develop prototypes and iterate designs based on testing and validation results.
• Ensure designs comply with performance, safety, and regulatory standards.
• Plan, execute, and document mechanical testing and product verification.
• Conduct failure analysis and root-cause investigations on components and assemblies.
• Support environmental and qualification testing (e.g., vibration, thermal cycling, shock).
• Lead mechanical engineering projects, from concept through production, ensuring timelines and budgets are met.
• Work closely with electrical, RF, and software teams to integrate mechanical solutions.
• Mentor junior engineers and technicians, providing guidance on design practices and problem-solving.
• Prepare and maintain detailed engineering drawings, specifications, BOMs, and test reports.
• Ensure compliance with quality standards (ISO 9001, AS9100) and industry regulations.
• Support design reviews, audits, and technical presentations to stakeholders.
• Collaborate with manufacturing teams to ensure designs are producible and maintainable.
• Review and approve engineering change requests (ECRs/ECNs) related to mechanical systems.
• Address production issues, provide corrective solutions, and implement process improvements.
• Research and implement new materials, methods, and technologies to improve product performance and reduce cost.
• Identify opportunities for efficiency, reliability, and performance enhancements in existing designs.

Preferred Qualifications:

• Must be a U.S. Citizen with the ability to obtain Secret Clearance.
• Bachelor’s degree in Mechanical Engineering or related field.
• 7+ years of mechanical design and engineering experience.
• Proficiency in CAD software (SolidWorks, CATIA, or similar).
• Experience with mechanical analysis tools (FEA, thermal, vibration, stress analysis).
• Strong understanding of materials, manufacturing processes, and mechanical systems.
• Excellent problem-solving, communication, and documentation skills.
• Experience in aerospace, defense, RF systems, or high-precision manufacturing.
• Knowledge of ISO 9001, AS9100, or other quality systems.
• Experience with 3D printing, composites, or advanced materials.
• Familiarity with project management tools and processes.
