• Own the mechanical architecture for advanced antenna, plasma-device, electronics, and communications-system hardware.
• Lead mechanical design reviews, establish analysis and documentation standards, and guide critical decisions involving performance, risk, cost, schedule, and manufacturability.
• Define modular product architectures that can evolve from laboratory prototypes to fieldable systems and future product variants.
• Mentor engineers and provide trusted technical guidance across multidisciplinary programs.

• Create and maintain CAD models, production drawings, GD&T schemes, tolerance analyses, bills of material, and configuration-controlled design documentation.
• Perform or direct thermal and structural analyses for electronics, antenna assemblies, plasma devices, and environmental loads.
• Select materials and joining methods for high voltage, RF exposure, thermal cycling, vacuum or controlled environments, and rugged use.
• Engineer interfaces involving ceramics, metals, seals, brazed or bonded joints, precision alignment, thermal expansion, shock, vibration, and fatigue.

• Drive rapid hardware iteration from concept through prototype, integration, environmental test, qualification, and design release.
• Design fixtures and test articles; support instrumentation, assembly, troubleshooting, root-cause analysis, and corrective action.
• Define test procedures and acceptance criteria that retire the highest mechanical risks and produce defensible design evidence.
• Correlate thermal and structural predictions with measured hardware behavior and incorporate learning into subsequent designs.

• Apply DFM and DFA principles while preserving RF, plasma, thermal, structural, and serviceability requirements.
• Lead technical engagement with machine shops, specialty joining and brazing vendors, additive manufacturers, and contract manufacturing partners.
• Review quotes, supplier capabilities, first articles, inspection results, nonconformances, and corrective actions.
• Establish repeatable assembly, inspection, quality, and configuration-management processes.

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Materials Engineering, or a related field.
• 7+ years of relevant mechanical product-development experience, including technical ownership of complex electromechanical hardware through design, build, integration, and test.
• Advanced proficiency with a modern 3D CAD platform, production drawings, GD&T, and tolerance analysis.
• Strong command of thermal management, structural mechanics, materials selection, and manufacturing processes.
• Demonstrated ability to lead design reviews, mentor engineers, communicate technical risk, and make sound decisions with incomplete information.
• Hands-on experience with experimental hardware and disciplined technical documentation.
• Ability to meet requirements associated with work on U.S. government and national-security programs.

• Experience with antenna systems, RF electronics packaging, aerospace hardware, high-voltage equipment, vacuum systems, or plasma devices.
• Experience with ceramics, metal-ceramic interfaces, brazing, adhesives, seals, coatings, or high-temperature assemblies.
• Proficiency with finite-element thermal or structural analysis and model-to-test correlation.
• Experience supporting environmental qualification, including shock, vibration, temperature, ingress, or related testing.
• Experience in an early-stage company, rapid-prototyping organization, defense program, or SBIR/STTR environment.
• Active U.S. security clearance or eligibility to obtain one.
