- Develop packaging approaches that support performance, assembly, access, and integration needs.

- Perform structural design work for brackets, housings, mounts, and other load-bearing hardware.

- Coordinate vehicle integration tasks with systems, electrical, manufacturing, and test stakeholders.

- Prepare technical content for design reviews and engineering assessments.

- Evaluate design trades involving mass, packaging, interfaces, manufacturability, and structural performance.

- Lead mechanical engineering activities to support prototype design, built, and test efforts.

- Document mechanical design decisions and release-ready engineering artifacts.

- Execute engineering work products from requirements through verification and technical documentation.
- Collaborate with cross-functional teams to integrate hardware, software, and operational constraints into practical solutions.
- Conduct technical analysis, risk identification, and trade studies to support design decisions.
- Present technical status, issues, and recommendations in formal and informal reviews.
- Contribute to proposal, planning, and execution activities aligned to program milestones.
- Support compliance with customer, regulatory, and security requirements.
- Travel up to 25% to support integration, test, customer engagement, and program execution.
- Support work performed in a classified and or controlled environment.
- Design, layout, test, and evaluate mechanical and electro-mechanical devices or subsystems.
- Perform engineering calculations and analysis to validate design robustness and reliability.
- Prepare technical specifications, design documentation, and recommendation packages for review.
- Partner with electrical, systems, manufacturing, and quality teams to mature integrated designs.
- Support prototype build, test, issue resolution, and transition to production.
- Develop detailed mechanical models, layouts, and design packages supporting prototype and production release.
- Perform structural assessments to verify load paths, margins, and compliance with mechanical requirements.
- Evaluate vibration and dynamic response characteristics across development and qualification activities.
- Conduct stress and fatigue evaluations to support durability, life predictions, and design refinement.

Qualifications:

- Bachelor’s Degree and minimum 6 years of prior relevant experience. Graduate Degree and a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years of prior related experience.
- Ability to obtain and maintain a DoD security clearance.
- 6+ years of experience in mechanical design and analysis for complex products.
- 6+ years of experience interpreting customer technical requirements and translating them into implementable design artifacts.
- 6+ years of experience with material, component, and process selection decisions.

Preferred Additional Skills:

- Bachelor of Science in a STEM discipline preferred; Engineering preferred, Physics, Mathematics, and Computer Science acceptable.
- Demonstrated ability to work effectively in cross-functional engineering teams.
- Experience with environmental and qualification testing, for example MIL-STD-810.
- Experience with design-for-manufacture and design-for-assembly practices.
- Experience in root-cause analysis and corrective-action implementation.
- Experience with mechanical modeling and design workflows for complex assemblies, cabling and harnesses, and packaging constraints in Creo 10.
- Experience with structural analysis methods and interpretation of stress and deflection results.
- Experience with dynamic analysis, vibration environments, and modal response interpretation.
- Experience with stress and fatigue assessment methods and life-cycle durability trade studies.
- Role scope expectation: Manages complex projects or processes with general oversight and delivers moderate-to-substantial process and system improvements.
- Collaboration expectation: Works within and outside the function to gain cooperation on operational practices and execution decisions.

- Experience with packaging design for dense electro-mechanical systems.

- Experience with structural analysis and design margin assessment.

- Experience supporting hardware integration and qualification activities.

- Familiarity with vehicle interfaces and system-level integration constraints.

- Experience conducting or supporting technical trade studies.
