RF / Microwave Engineer
As an RF/Microwave Engineer, you will design, simulate, prototype, and validate RF front-end circuits for high-performance datalink systems operating in sub-6 GHz and microwave frequency bands. You will develop signal chain architectures including power amplifiers, low-noise amplifiers, mixers, filters, and frequency synthesis stages to ensure robust and reliable communication links.
About the Role
Join our engineering team to develop advanced RF subsystems for next-generation datalink platforms. You will focus on RF circuit design and system integration, working closely with antenna, DSP, mechanical, and software teams to deliver high-performance communication hardware.
This role combines circuit design, system-level analysis, hands-on lab validation, and automated test development in a fast-paced engineering environment.
Responsibilities
Design and simulate RF front-end circuits across RF and microwave frequency bands
Develop power amplifier stages, low-noise amplifiers, mixers, filters, and frequency generation circuits
Perform RF cascade analysis including gain, noise figure, linearity, stability, and dynamic range
Conduct link budget analysis and support system-level RF performance optimization
Create circuit-level and system-level simulations using industry-standard RF design tools
Design schematics and support PCB layout for high-frequency circuits
Collaborate with cross-disciplinary teams to integrate RF subsystems into complete datalink systems
Develop validation and production test methodologies for RF hardware
Perform lab characterization using network analyzers, spectrum analyzers, signal generators, and related instrumentation
Requirements
Bachelor’s degree in Electrical Engineering, Physics, or related discipline
3+ years of industry or research experience in RF/microwave circuit design
Experience designing RF signal chain components such as PAs, LNAs, mixers, filters, or PLLs
Strong understanding of impedance matching, S-parameters, noise figure, linearity, stability, and RF system fundamentals
Experience with RF test equipment (VNA, spectrum analyzer, signal generator, power meters)
Experience with RF simulation tools such as ADS, AWR, or similar
Nice to Have
Experience designing high-linearity or high-efficiency power amplifiers
Experience with RF system-level modeling and link analysis
Familiarity with digital modulation schemes (QPSK, QAM, APSK) and their RF implications
Experience with PCB schematic and layout tools (Altium or equivalent)
Experience developing automated RF test solutions
Experience working in datalink or high-reliability communication systems
