Job Overview :

We are seeking experienced Senior IC Design Engineers to support the design and development of RF silicon ICs central to our tuneable front-end module technology. This includes the design of wideband low noise amplifiers (LNAs), RF switches, and digitally tuneable capacitors (DTCs), along with supporting analog and mixed-signal blocks.

You will collaborate closely with our IC design service partner and internal RF module team to ensure seamless integration and co-simulation of IC and module behaviour, while contributing to performance optimization.

Key Responsibilities :

• Design and develop RF IC building blocks including wideband LNAs, RF switches, DTCs, and supporting analog / mixed-signal circuits.
• Support silicon RFIC circuit integration into multi-chip module (MCM) assemblies.
• Set up co-simulation environments, including the development of simulation models and execution of top-level MCM simulations.
• Evaluate circuit performance through simulation and lab measurement, refining designs to achieve high predictability.
• Use RF measurement equipment and troubleshoot measurement-related issues.
• Contribute to IC design planning, risk analysis, and performance alignment.
• Conduct high-level simulations including Monte Carlo and corner case analysis.
• Document designs, simulation results, and measurements for internal and external review.
• Collaborate effectively across internal and external teams, facilitating communication between IC and module design functions.
