Position Summary
As the Senior Mechanical Engineer for lead the mechanical design and packaging efforts for enclosures and electronic components for ground based and space based communication and radar systems. Your expertise will ensure robust, reliable packaging solutions for RF, microwave, power electronics, control, and other components and systems. Design for compliance to specification including environmental.

Key Responsibilities
• Design and develop mechanical enclosures and packaging for electronic components and systems.
• Conduct reviews and optimizations of existing mechanical designs to enhance reliability, thermal management, vibration resistance, and environmental protection for maritime, terrestrial and space operations.
• Collaborate with cross-functional teams, including electrical engineers, radar specialists, program management to integrate mechanical packaging into overall system repair processes and logistics.
• Perform structural analysis, thermal simulations, and reliability assessments to meet high-reliability requirements in harsh environments.
• Develop test plans and procedures for validating mechanical enclosures, including environmental testing for shock, vibration, humidity, and salt fog exposure.
• Troubleshoot mechanical issues in radar subsystems, recommending repairs or redesigns.
• Mentor junior mechanical engineers on best practices for packaging and mechanical design.
• Ensure compliance with security, safety, and regulatory standards, including ITAR and classified information handling.
• Travel as needed to customers, test facilities, or vendor sites for mechanical evaluations and integrations.

Required Qualifications
• Bachelor's degree in Mechanical Engineering, Physics or a related field; Master's degree preferred.
• 8+ years of experience in mechanical engineering, with direct hands-on expertise in enclosures and mechanical packaging of electronic components such as power supplies, computers, and RF/Microwave systems.
• Prefer proven experience in DoW systems, including design or repair of mechanical enclosures for complex electronics.
• Active U.S. security clearance is a plus but must be able to obtain secrete clearance.
• Strong knowledge of mechanical design principles, including materials selection, thermal management, and structural integrity for electronic packaging.
• Proficiency/Expert Level in CAD software such as SolidWorks for design and simulation.
• Excellent problem-solving and communication skills for technical reporting and team collaboration.

Preferred Qualifications
• Experience in mechanical enclosures and packaging of high-power RF transmitters, RF receivers, antennas, and support electronics.
• Familiarity with reliability requirements for MIL-STD compliance for shock, vibration, and environmental stressors.

What We Offer
• Competitive salary and performance-based bonuses.
• Comprehensive benefits package, including health insurance, 401(k) matching, paid time off, and professional development opportunities.
• Opportunity to contribute to national defense in a high-impact role.
• Collaborative work environment with access to cutting-edge tools and facilities.
