• Translate system requirements into block diagrams, schematics, and hardware solutions.
• Design and develop RF, microwave, mixed‑signal, and power circuitry.
• Create schematics, select components, and support PCB/CCA design.
• Contribute to integrated RF assemblies including amplifiers, filters, mixers, LNAs, PAs, and related subsystems.
• Perform RF and microwave simulation and analysis.
• Use industry‑standard tools such as HFSS, ADS, Genesys, SPICE, and MATLAB.
• Analyze performance across frequency, noise, gain, linearity, and signal integrity domains.
• Hands‑on hardware bring‑up, debug, and test.
• Use lab equipment including oscilloscopes, spectrum analyzers, vector network analyzers, signal generators, and power supplies.
• Work as part of a multidisciplinary engineering team collaborating closely with systems, mechanical, firmware, manufacturing, and test engineers.
• Support design reviews and technical trade studies across the full lifecycle.
• Lead small projects or technical efforts.
• Mentor junior engineers and contribute to technical decision‑making.
• Occasional travel to support integration activities at Raytheon facilities, subcontractors, or customer sites as needed.
