RF Device Modeling Engineer (f/m/x)

Kuching, Malaysia

Join our RF Technology Team. In this position you will work in a highly interactive environment with a mission to deliver RF technology solutions.  The central role will be a RF modeling engineer responsible to create and validate device models that are suitable for high-frequency applications.  We are seeking qualified candidates with a background in device physics and experience in RF device modeling. 


  • Modeling of semi-conductor devices for radio-frequency applications using industry state of the art compact models such as PSP, UT-SOI, BSIM, HICUM, ASM-HEMT and others
  • Extracting SPICE model parameters using industry modeling software such as Keysight IC-CAP. Synthetize their model cards and verify their compatibility with simulation environment.
  • Create sub-circuit type models and provide their codes in VerilogA. Validate their accuracy against experimental data
  • Elaborating statistical models for global (wafer to wafer) and local (Matching) process variation
  • Design and implementation of layouts (test chips) for DC, CV and RF characterization allowing extraction of device electrical properties
  • Work closely with the characterization engineers on defining measurement conditions requirement for model parameter extraction
  • Work with colleagues from PDK team on delivering model cards and verifying their functionality after integration
  • Generate model characteristics documentations for their delivery to customers
  • Support business development on an as-needed basis to resolve client questions or issues.
  • Strong collaboration and teamwork
