SENIOR ELECTRO-MECHANICAL ASSEMBLER at DIAMOND ANTENNA & MICROWAVE

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.
