Job description


Builds on 30-year legacy of technology advancements and strong IP portfolio but with a new mission— to enhance world-class capabilities with high-performance semiconductors. With a strong foundation in RF integration, their product portfolio now spans power management, connected sensors, optical transceivers, antenna tuning and RF frontends.

These intelligent and efficient semiconductors enable advanced modules for smartphones, base stations, personal computers, electric vehicles, data centers, IoT devices and healthcare. From headquarters in San Diego and offices around the world, team explores new ways to make electronics for the connected world smaller, thinner, faster, and better


The Staff RF Characterization Engineer is responsible for validating leading edge RF Integrated Circuits, developing of measurement systems of RFICs for mobile wireless and commercial/industrial applications, focusing on test solutions for mobile RF Front End ICs such as RF switches, LNAs, and Power Amplifiers. The job requires expertise in RF and analog measurements to ensure that projects are accurately characterized prior to release, combined with disciplined project planning to ensure that schedules are met. The Staff Characterization Engineer will be expected to manage the project schedules, generate system specifications, and create effective measurement solutions.

  • Characterization: Work close with product designers to develop, evaluate and maintain optimum characterization plans for new product development. In addition to the characterization process, these include standard for conditions, quantities, and inprocess QA criteria as a function of parameter types.
  • Data Analysis Standards: Develop, evaluate, and maintain data analysis standards covering statistical limit setting (including methods for aggregating statistics), yield prediction tools (Cpk analysis), tools and formats as a function of the parameter type.
  • Characterization Infrastructure: Design and development of software and hardware for design validation, performance optimization, characterization, and production test of RFICs. Analysis and development of optimization techniques for rapid characterization and test.
  • Analysis Tool Development: Develop characterization and test data analysis tools to streamline characterization (CPK analysis) and improve ATE capability understanding (GR&R)
  • Status Reporting: Be a technical leader through strong example and training of more junior engineers and provide continuous status updated to upper management and stakeholder
