RF Design Engineer (RFIC)

About the role

An experienced RF Design Engineer at Staff, Senior Staff or Principal level is sought, with strong hands-on experience in RFIC and analog circuit design. The engineer turns system-level requirements into high-performance RF solutions, leading design, prototyping, validation and deployment of RF technology modules, and works with internal teams, customers and suppliers.

Key responsibilities

• Translate system requirements into technical specifications, assess feasibility and perform RF system budget analysis (gain, noise figure, linearity, power consumption).
• Define RF transceiver architectures and manage design risks.
• Design active and passive RF/analog IP blocks such as TIA, driver amplifiers, VCO, PLL, LNA, PA and mixers.
• Optimize circuits for impedance matching, noise figure, linearity and power efficiency.
• Run EM simulations with field solvers for on-chip parasitics, inductors, transformers and transmission lines.
• Handle RF IC custom layout, DRC/LVS verification and parasitic extraction; work with layout engineers on floorplanning, routing and post-layout optimization.
• Take part in design reviews, set design methodologies and support chip bring-up, silicon validation and debugging.
• Conduct high-frequency lab testing with VNAs, spectrum analyzers and RF probe stations.
• Research new circuit topologies, semiconductor nodes and RF techniques, and prepare technical documentation.

Required profile

• Strong hands-on experience in RFIC and analog circuit design.
• Experience with advanced nodes, especially FDSOI and FinFET.
• Understanding of RF fundamentals: Smith charts, transmission-line theory, wave propagation and substrate noise coupling.
• Experience with RF silicon characterization and high-frequency measurement equipment.

Required skills

• RF circuit simulation and electromagnetic simulation
• Custom layout and post-layout verification (DRC/LVS)
• High-frequency measurement equipment
