Originally posted 14 October 2026 by the employer.
About the role
As a Principal RFIC Design Engineer, you will be responsible for the design of high performance analog and mixed-signal circuit blocks.
What you'll do
- Design transistor level, block level, and module level circuit architecture.
- Perform simulation, optimization, and layout supervision.
- Conduct product characterization, reliability, and yield assessment.
- Evaluate silicon and application-level bench performance.
- Prepare test plans and documentation.
What you'll need
- Hands-on design and development experience in analog and mixed-signal integrated circuit.
- Experience in full CMOS circuit design in Amplifiers (operational, instrumentation, wide-bandwidth), PMIC (Linear and switched regulators, Low-drop out regulators), or Data converters (ADC, DAC, Flash and SAR type).
- Experience in 40nm and below CMOS technology.
- Demonstrable track record of successful design releases and mass production.
- Thorough knowledge of industry standard EDA tools (Cadence, Mentor, Siemens, Ansys).
- Experience with analog layout techniques of mismatch reduction, gradient suppression, parasitic effects minimization.
- Experience with floor planning, block level routing, and top level chip routing.
- Knowledge of high performance and deep CMOS analog reliability considerations such as EM-IR, SOA, and VDR and relevant mitigation techniques.
- Functional knowledge of logic digital circuits and understanding of basic digital design flow.
- BSEE with minimum 10+ years of experience, MSEE with minimum 8+ years of experience, or PhD with minimum 4+ years of experience.
Nice to have
- Experience working with distributed design teams.
