Mechanical Engineer II​/III Security Clearance

Position: Mechanical Engineer II/III with Security Clearance
About the Role We are seeking a highly skilled Mechanical Engineer to support the design, analysis, and integration of advanced electronic and electromechanical systems. This role focuses on mechanical design for electronics, including enclosure development, PCB-mechanical integration, and structural validation for ruggedized and mission-critical applications. The ideal candidate brings strong CAD design expertise, hands-on experience collaborating with electrical engineers, and deep knowledge of structural, thermal, and vibration analysis.

This role plays a critical part in ensuring mechanical integrity, reliability, and manufacturability across the product lifecycle.

Key Responsibilities
* Design and develop mechanical components, enclosures, and assemblies for electronic systems
* Perform CAD modeling and detailed drawings to support prototype and production builds
* Collaborate closely with electrical engineers to ensure accurate PCB-to-mechanical integration
* Use Altium MCAD Co Designer to synchronize mechanical and PCB design changes
* Conduct finite element analysis (FEA) to validate structural integrity
* Perform stress analysis, including torsional rigidity of enclosures and PCB mounting systems
* Execute shock and vibration analysis for ruggedized environments
* Perform thermal analysis to ensure adequate cooling and thermal performance
* Support design-for-manufacturing (DFM) and design-for-assembly (DFA) best practices
* Document analysis results, assumptions, and design decisions
* Support prototype builds, testing, and design iteration

Required Qualifications
* Bachelor's degree in Mechanical Engineering or related field
* 5-7 years of professional experience as a Mechanical Engineer in product development or system design
* Strong CAD design experience for mechanical and electromechanical systems
* Proficiency in one or more of the following CAD tools:
* Solid Works
* Fusion 360
* AutoCAD
* Creo
* Hands-on experience using Altium MCAD Co Designer  
* Experience performing Finite Element Analysis (FEA)
* Proven capability in stress analysis and structural validation
* Experience analyzing PCB and enclosure torsional rigidity
* Experience performing shock and vibration (shock & vibe) analysis
* Experience with thermal analysis for electronic systems

Preferred Qualifications
* Experience with Computational Fluid Dynamics (CFD)
* Hands-on experience with additive manufacturing / 3D printing for rapid prototyping
* Familiarity with EMI shielding and mechanical mitigation techniques
* Experience with cable and wire harness design and routing
* Experience working on ruggedized, aerospace, defense, or industrial systems Security Requirements
* U.S. Citizenship required
* Must be eligible to obtain and maintain a U.S. security clearance Application Process Interested candidates should submit:
* A resume or CV highlighting relevant experience Visa Statement:
We do not provide visa sponsorship for this role. Candidates requiring immigration support (e.g., H-1B, TN, OPT, or similar) should not apply. Why Join Us?

This role offers the opportunity to work on complex, high-impact systems where mechanical design directly influences product performance, reliability, and mission success.
