• Provide technical mentoring to other design team members; partner with design management on resource planning, technical priorities, risk assessment, and cross-functional execution.
• Lead the development, validation, and deployment of AI-enabled RFIC design automation methodologies that improve IC product development efficiency, quality, engineering insight, and time to market.
• Identify, prioritize, and implement opportunities for EDA workflow orchestration, simulation execution and analysis, design-space exploration, verification, documentation, and product debug.
• Partner with software and AI engineers to integrate these capabilities into scalable, validated, and reusable engineering workflows.
• Develop ICs in RF SOI and other appropriate semiconductor technologies for RF frontend platform products.
• Lead and provide technical direction in product design, including schematic capture, IC layout, simulation, package analysis, evaluation board development, test plan creation, validation, and product release.
• Document relevant product, design, and methodology information to educate others on novel design techniques, enable reuse of engineering knowledge, and provide guidance on product usage. Support the development of structured engineering knowledge that can be leveraged by AI-enabled tools and workflows.
• Lead cross-functional teams to achieve industry-leading product performance and meet development goals. Create, track, and report program technical milestones, identify technical risks, and drive resolution of critical design issues.
• Identify opportunities where AI, automation, and advanced design methodologies can materially improve RFIC development. Evaluate emerging technologies, lead proof-of-concept activities, and drive establishment of methodologies that can be leveraged across multiple products and design teams.
• Collaborate with Applications, Characterization, Product, Test, and Manufacturing Engineers to answer customer questions, assess field failures, support yield improvements, resolve production issues, and improve product performance and robustness.

Minimum Qualifications (Experience and Skills)

• 9+ years of relevant RFIC design and product development experience, including demonstrated ownership of complex RFIC designs from concept through production release.
• Expertise designing RFIC products in RF SOI, bulk CMOS, and/or BiCMOS technologies, with deep experience in one or more areas such as LNAs, RF switches, power amplifiers, RF frontend control circuitry, or other RF/analog building blocks.
• Strong understanding of analog biasing and control circuitry.
• Excellent RF design and analysis skillset, including knowledge of S-parameters, noise figure, stability, P1dB, harmonics, IMD, IIP2/IIP3, and the capability to design for and measure each parameter.
• Strong understanding of CMOS devices and semiconductor technologies as they relate to circuit- and product-level performance tradeoffs.
• Demonstrated ability to lead technical development and help develop the technical skills of other engineers.
• Advanced working knowledge of analog and RF IC layout techniques and physical design considerations.
• Strong programming or scripting capability for engineering automation, preferably including Python.
• Experience developing or applying design-flow automation techniques to semiconductor or RF engineering workflows.
• Familiarity with generative AI, large language models, agentic AI, or related AI-enabled engineering technologies.
• Ability to evaluate AI-generated engineering results and establish appropriate validation and human-review methodologies.
• Demonstrated ability to communicate and document design work, technical decisions, tradeoff analyses, and methodologies with clarity, completeness, and audience-appropriate detail.
• Proficiency with RF IC EDA tools including Cadence Virtuoso, Keysight ADS, and EM simulators such as EMX and HFSS.
