Mechanical Engineer, RF Systems

Job description

Job responsibilities

• Own end-to-end mechanical design for antenna and RF assemblies, including architecture, packaging, CAD, drawings, specifications, tolerance analysis, BOMs, and production release.
• Translate link-budget, antenna-pattern, polarization, isolation, desense, environmental, structural, and vehicle-level requirements into measurable mechanical constraints.
• Establish antenna placement, orientation, keep-out, ground-plane, separation, and installation requirements across vehicle structures and avionics assemblies.
• Design antenna mounts, radomes, housings, RF shields, feedline routing, connector interfaces, strain relief, grounding features, and serviceable module assemblies.
• Define mechanical shielding, seam, gasket, grounding, and bonding strategies that contain digital and power-system emissions while avoiding unintended antenna effects.
• Partner with RF and Test engineers on measurements including S-parameters, VSWR , insertion loss, antenna efficiency, gain, radiation pattern, polarization, isolation, desense, and environmental performance.
• Create fixtures and representative structures that allow chamber and bench measurements to reproduce the installed mechanical configuration.
• Perform structural, thermal, vibration, fatigue, and tolerance analyses to ensure RF assemblies remain physically stable and electrically repeatable throughout operating life.
