RF Systems Engineer (Front-End + Antenna)
Core Mission
Core Mission
Design and validate high-sensitivity RF sensing systems, including antennas and front-end architectures, optimized for weak, indirect, and environment-affected signals.
Key Responsibilities
RF Front-End & System Design
RF Front-End & System Design
• Architect low-noise, high dynamic range RF chains (LNA → filtering → conversion → digitization)
• Design for weak signal acquisition in multi-path, interference-rich environments
• Optimize system-level performance: noise figure, linearity, selectivity, and dynamic range
• Perform RF link and propagation analysis including Doppler, attenuation, and polarization effects
Antenna & EM System Design
• Design and optimize antennas for wide-area sensing and signal capture, including multi-band / wide-band antennas
• Develop directional and quasi-omnidirectional patterns depending on mission needs
• Evaluate gain vs coverage trade-offs, polarization behavior, and radiation efficiency
• Develop antenna + RF co-design strategies (impedance matching, feed integration)
• Use HFSS/CST for radiation pattern optimization, coupling analysis, and platform effects
• Support antenna calibration and field characterization for multi-channel systems
Signal Environment Awareness
• Account for signal reflections, scattering, and propagation-induced distortions
• Design systems robust to multi-path interference, time-varying signal conditions, and frequency/phase instability
Validation & Testing
• Develop RF and antenna test plans including S-parameters, radiation patterns, and efficiency
• Validate sensitivity, detection thresholds, and interference response
• Support an-echoic chamber and field testing
• Collaborate with backend teams for system validation
What We’re Looking For
• A deep understanding that antenna defines observable signals
• Experience in antenna + RF co-design and real-world signal conditions
• Experience with wide-band and multi-frequency sensing systems
Core Competencies
• Electromagnetism & antenna theory
• Transmission lines and impedance matching
• HFSS/CST (must-have), ADS (good-to-have)
• RF lab equipment (VNA, spectrum analyzer)
