Support development of test plans and calibration strategies for antenna performance, including planar near-field testing, beam pattern verification, and RF alignment.

Evaluate and support mitigation of mechanical and RF degradation, such as corrosion, delamination, or waveguide performance loss.

Support development of repair and refurbishment procedures, depot-level maintenance strategies, and facility/equipment requirements for organic sustainment.

Provide technical input to training materials, documentation, and Integrated Technical Data Packages (ITDPs).

Interface with systems engineering and test teams to ensure alignment with weapon system performance requirements and downstream subsystem dependencies.

Minimum of 10 years of experience supporting phased array radar systems, including direct experience with AN/SPY-1 antenna subsystems.

In-depth understanding of phased array theory, T/R isolation, beamforming networks, and mechanical integration of RF components.

Hands-on experience with antenna test systems, including near-field scanners, RF pattern analysis, and calibration tooling.

Familiarity with shipboard radar installation, environmental considerations, and corrosion-resistant material design.

Ability to review and develop technical drawings, RF interface documentation, and test procedures.

Active Secret Clearance

Preferred Qualifications:
