RF Systems Engineer

About the Role

Responsibilities

• Own the design, integration, characterization and performance of the analog RF receive and transmit chains
• Work with high-power transmit hardware, including power amplifiers, combiners, couplers, transmission lines and protection systems; characterize gain, efficiency, linearity, harmonics, thermal behavior and load-mismatch tolerance
• Design and optimize impedance-matching and tuning solutions for changing antenna loads, balancing bandwidth, power handling, efficiency and reflected power
• Develop and integrate low-power receive chains, including LNAs, filters, switches and matching networks
• Work with antennas and antenna arrays: impedance, bandwidth, radiation performance, feed systems, phasing and mutual coupling
• Simulate antennas and antenna arrays with electromagnetic simulation tools such as NEC, FEKO, CST or HFSS, and validate simulations against measurements
• Combine simulation, analytical modeling and measurement in Python to identify dominant system limitations, and work with system, algorithm and modeling engineers to investigate trade-offs and validate improvements across link budgets, cascaded gain and noise, nonlinear effects and array behavior
• Specify requirements toward suppliers: translate system objectives into clear specifications, find and evaluate antenna manufacturers and RF equipment vendors, and manage supplier engagements from first contact through quotation, delivery and acceptance testing
• Define and execute test strategies at component, subsystem and integration level, covering test setups, acceptance criteria, calibration and measurement uncertainty

Requirements

• BS or higher in Electrical Engineering, RF/Microwave Engineering, Applied Physics or a related discipline
• Minimum 3 years of hands-on experience with RF hardware or RF systems
• Strong foundation in analog RF: think naturally in terms of S-parameters, matching and cascaded gain and noise, and understand how antenna impedance and load mismatch affect the performance of the whole system
• Good understanding of low-noise receiver design (noise figure, sensitivity, dynamic range)
• Good understanding of antennas and antenna arrays (radiation patterns, phasing, mutual coupling)
• Strong measurement skills with VNAs, spectrum/signal analyzers, oscilloscopes, signal generators and RF power meters, and the ability to design meaningful, repeatable measurement setups
• Analytical mindset: able to describe physical RF behavior with equations, simplified models and numerical simulations, and correlate those models with measurements
• Solid foundation in Python for analysis, modeling and measurement automation, and fundamentals of digital signal processing (sampling, filtering, spectral analysis)
• Good communication and project management skills or a clear willingness to develop them: can write unambiguous requirements and specifications, coordinate with external suppliers, and drive engagements to completion
• Comfortable owning open-ended engineering problems from first investigation through design, experimentation and validation, and communicating trade-offs across disciplines
