• Understanding of requirement allocation and flow-down from system to component level.
• Knowledge of cost estimating, budget, and schedule management.
• Strong academic background in Microwave Engineering, Microwave Systems, Electromagnetic Theory, and Radar Systems.
• Hands-on experience with microwave testing techniques using spectrum analyzers, Real-time Spectrum Analyzers (RSAs), Vector Network Analyzers (VNAs), and Performance Network Analyzers (PNAs).
• Team leadership, proposal writing, and presentation experience.

Benefits

• Medical, dental, and vision insurance.
