Job summary

Red Cell Partners is seeking a Staff Mechanical Engineer to serve as the senior mechanical owner for plasma‑enabled antenna and advanced communications hardware. You will shape mechanical architecture, drive critical design trades, and lead assemblies, plasma devices, electronics housings, and test fixtures from concept through qualification‑ready designs.

You will mentor engineers, define modular architectures, and ensure rigorous documentation, with a focus on RF, high‑voltage, thermal, and

Qualifications

• 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.

Responsibilities

• 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, BOMs, 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.
• 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.
