Description

Description A Senior Electro-Mechanical Assembler (RF Rotary Joints) is responsible for the precision mechanical and electrical assembly of high-frequency rotary joints used in radar, satellite communication, EW, and other mission-critical aerospace systems. This role combines micron-level mechanical tolerancing with RF performance awareness, ensuring assemblies meet tight VSWR, return loss, and insertion loss specifications across wide frequency bands. Requirements Primary Responsibilities Assemble RF rotary joints and slip ring hybrids integrating precision bearings, waveguide or coaxial interfaces, and slip contacts. Route and terminate RF cables (SMA, SMP, TNC, or custom coax types) ensuring impedance continuity and minimal reflection. Apply torque specs on threaded RF connectors, couplers, and precision fasteners using calibrated tools per engineering drawings. Interpret detailed mechanical and RF assembly drawings, wiring diagrams, BOMs, and test procedures under ITAR control. Perform verification testing (continuity, isolation, DC resistance, and rotation smoothness); assist with RF test setups. Document builds per AS9100, MIL-STD-883, and IPC-J-STD-001 standards, maintaining full lot traceability. Collaborate with engineering on mechanical fit-ups, grounding, or preload adjustments to optimize RF performance. Support process improvement by developing build checklists, torque charts, and ESD control enhancements. Train junior assemblers in coax cable prep, soldering, and connector termination best practices. Required Skills & Technical Knowledge 8–12 years of precision electro-mechanical assembly experience; RF rotary joint or slip ring assembly preferred. Expertise in coaxial assembly and soldering (RG-405, RG-316, semi-rigid coax) to MIL-STD-348 standards. Skilled with bearing fits, seal installation, and axial preload adjustment using micrometers and torque tools. Familiar with clean assembly environments and static control procedures (ESD/EOS). Able to interpret mechanical tolerances (±0.001") and RF interface callouts. Experience in defense documentation workflows (FOD control, DHRs, NCR/MRB). Certifications / Standards IPC-A-610 Class 3 and J-STD-001 certification required or strongly preferred. Knowledge of MIL-STD-2000, AS9100, and ITAR compliance mandatory. ESD / FOD awareness, precision assembly, and RF safety handling required.
