RF Design Engineer

Role Overview

We are seeking experienced RF Design Engineers at Staff, Senior Staff, or Principal level with strong hands-on experience in RFIC and analog circuit design.

The successful candidate will play a key role in translating system-level requirements into high-performance RF solutions. This includes leading design, prototyping, validation, and deployment of RF technology modules.

You will collaborate with internal engineering teams, customers, and external suppliers to develop commercially viable solutions while contributing to the company’s long-term technology and product strategy.

Key Responsibilities

• Translate system requirements into technical specifications, assess feasibility, and perform RF system-budget analysis, including gain, noise figure, linearity, and power consumption.

• Define optimal RF transceiver architectures and manage associated design risks.

• Design high-performance active and passive RF/analog IP blocks, including TIA, driver amplifiers, VCO, PLL, LNA, PA, and mixers.

• Optimize circuit performance for impedance matching, noise figure, linearity, and power efficiency.

• Perform electromagnetic (EM) simulations using advanced field solvers to model on-chip parasitics, inductors, transformers, and transmission lines.

• Independently handle RF IC custom layout, DRC/LVS verification, and parasitic extraction.

• Collaborate with layout engineers on floorplanning, routing, and post-layout optimization through iterative extraction and simulation.

• Participate in design reviews, provide technical guidance, establish design methodologies, and improve engineering workflows.

• Support chip bring-up, silicon validation, and debugging through test-plan development and measurement-data analysis.

• Conduct high-frequency laboratory testing using equipment such as VNAs, spectrum analyzers, and RF probe stations.

• Research emerging circuit topologies, advanced semiconductor nodes, and state-of-the-art RF design techniques.

• Prepare technical documentation and design reports throughout the development lifecycle.

Job Requirements

Technical Expertise

• • Strong hands-on experience in RFIC and analog circuit design.

  • Experience with advanced semiconductor technology nodes, particularly FDSOI and FinFET.

  • Strong understanding of RF fundamentals, including Smith charts, transmission-line theory, wave propagation, and substrate noise coupling.

  • Proficiency in RF circuit simulation, electromagnetic simulation, custom layout, and post-layout verification.

  • Experience with RF silicon characterization and high-frequency measurement equipment.
