RFIC engineer

About the Company

We are seeking an experienced RF Engineer with deep expertise in Power Amplifiers (PAs), Low Noise Amplifiers (LNAs), and Front-End Module (FEM) IC development. The role involves end-to-end design, simulation, validation, and optimization of RF circuits across X/Ku/Ka/E bands.

About the Role

We are seeking an experienced RF Engineer with deep expertise in Power Amplifiers (PAs), Low Noise Amplifiers (LNAs), and Front-End Module (FEM) IC development. The role involves end-to-end design, simulation, validation, and optimization of RF circuits across X/Ku/Ka/E bands.

Responsibilities

• Design, simulate, and layout PA, LNA, and FEM ICs for multi-band RF applications.
• Optimize RF performance for linearity, noise figure, gain, power efficiency, and bandwidth.
• Conduct EM simulations and ensure design robustness.
• Develop test plans and perform RF characterization using VNAs, spectrum analyzers, and other RF test equipment.
• Debug and resolve RF design issues throughout the development cycle.
• Guide junior engineers and support methodology improvements.

Qualifications

• Bachelor’s or Master’s in Electrical Engineering or related field.
• 8–10+ years of hands-on experience in RF IC design (PAs, LNAs, FEMs).
• Strong foundation in RF circuit theory, impedance matching, and transmission line concepts.
• Proficiency with RF design/simulation tools (ADS, AWR Microwave Office, or similar).
• Experience in RF measurements and lab debugging.
• Knowledge of GaN, GaAs, SiGe semiconductor technologies and RF IC processes.
