• Ability to evaluate and effect antenna performance
• Ability to guide the development of new antennas
• Design and analyze RF circuits, components, and system architectures for Diamond products.
• Perform RF measurements, including S-parameters, insertion loss, isolation, phase matching, and VSWR.
• Develop RF models and perform simulations using HFSS, CST, ADS, or similar tools.
• Support testing and qualification of RF assemblies and prototypes.
• Collaborate with mechanical engineers on electromechanical designs affecting RF paths.
• Troubleshoot RF performance issues during production or qualification.
• Generate engineering documentation: RF test reports, design notes, ECOs, configuration-controlled documentation.
• Mentor junior RF engineers and technicians.
• Leads complex RF design projects including new architectures and advanced modeling.
• Performs deep-dive investigations into RF failures and system-level issues.
• Mentor multiple engineers and influences RF standards/methodologies.
• Experience with RF, microwave, and millimeter-wave system design, testing, or integration.
• Familiarity with RF rotary joints, slip rings, FORJ systems, and supporting electromechanical architectures.
• Ability to design or analyze RF signal paths, impedance matching, insertion loss, VSWR, and isolation characteristics.
• Understanding of mechanical-RF interactions, including rotating interfaces, thermal constraints, and packaging.
• Experience with VNA/Spectrum Analyzer measurements, S-parameters, time-domain analysis, and RF troubleshooting.
• Working knowledge of AS9100, ISO 9001, ITAR/CUI requirements, and configuration-controlled engineering processes.
• Ability to collaborate with mechanical, manufacturing, and quality teams during prototype builds and root-cause investigations.
• Comfort generating documentation: RF test reports, engineering changes, qualification test procedures, and BOM structures.
• Familiarity with simulation tools such as HFSS, CST, ADS, or equivalent RF modeling environments.
• Commitment to disciplined engineering methodology and continuous improvement across Diamond's product lines.

Qualifications

• Bachelor's degree in Electrical Engineering with RF/Microwave concentration (Master's preferred).
