RF Engineer II (R6053)

Job description

Job responsibilities

• Design RF and microwave modules from requirements and architecture through schematic capture, component selection, layout, bring-up, verification, qualification, and production release, with scope and independence…
• Design active and passive RF circuits such as low-noise amplifiers, power amplifiers, filters and multiplexers, RF switches, limiters, couplers, attenuators, power detectors, and frequency-conversion stages.
• Develop RF front-end assemblies that meet gain, noise figure, output power, linearity, compression, efficiency, harmonic and spurious-emission, stability, isolation, and out-of-band rejection requirements.
• Perform circuit and electromagnetic analysis using tools such as Keysight ADS, Cadence AWR, HFSS, or CST, and correlate models with measured hardware performance.
• Create and review RF and mixed-signal PCB designs, including controlled-impedance routing, grounding, shielding, stack-up definition, power distribution, and placement of sensitive or high-power components.
• Plan and execute laboratory characterization using network analyzers, spectrum analyzers, signal generators, noise-figure analyzers, power meters, oscilloscopes, and automated test equipment.
• Diagnose difficult hardware issues involving instability, oscillation, intermodulation, self-interference, desense, thermal drift, mismatch, leakage, and electromagnetic coupling.
• Work closely with mechanical, thermal, avionics, communications, antenna, manufacturing, and test engineers to integrate RF hardware into size-, weight-, power-, cooling-, and environmental constraints.

Job requirements

• Bachelor's degree in Electrical Engineering, Applied Physics, or a related field, or equivalent practical experience.
• Typically 1 or more years of relevant post-undergraduate experience for L2, or 2 or more years for L3. Applicable graduate study and research may count toward experience.
• Hands-on experience designing, building, or debugging an RF or microwave circuit, module, or PCB assembly through measured verification.
• Solid understanding of S-parameters, impedance matching, transmission lines, stability, gain and noise figure, linearity and compression, nonlinear products, isolation, and cascaded RF performance.
• Experience creating or reviewing RF PCB layouts with controlled impedance, grounding, shielding, component placement, and signal-integrity considerations.
• Proficiency with common RF laboratory instruments and calibration methods, with the ability to distinguish hardware behavior from measurement artifacts.
• Ability to use simulation and measured data to make sound design decisions, document tradeoffs, and close requirements with objective evidence.
• Clear written and verbal communication skills and the ability to work effectively with cross-functional engineering and manufacturing teams.
