RF/analog/mixed signal IC Design Engineer



San Diego, CA, USA
Posted on Friday, June 7, 2024


Role Number:200554261
We are seeking a highly skilled RF, Analog, and Mixed Signal Engineer to join our engineering team. The ideal candidate will possess strong analytical abilities, a passion for innovation, and extensive experience in designing and implementing RF/mmW and/or analog/mixed-signal circuits. Our team is responsible for all aspects of silicon development for cellular transceivers, with a particular emphasis on highly integrated and efficient designs and technologies that transform the user experience at the product level. This highly visible role puts you at the center of a silicon design group with a critical impact on getting functional products to hundreds of millions of customers quickly!


As an RF IC design engineer, you will be responsible for providing RF solutions for cellular transceiver chips. Responsibilities include: Working with platform architects, system, and digital design groups to define the requirements for RF and baseband blocks based on the system requirements. Collaborating with the technology team on process selection for the target device. Driving transistor-level feasibility studies of RF/mixed-signal circuit blocks and architectures. Designing various component blocks inside the RF transceiver, including LNA, upconverters/downconverters, baseband filters, VGAs, LO/PLL circuits, driver amplifiers/power amplifiers, linear RF switches, attenuators, low noise regulators, amplifiers, and biasing circuits. Working closely with the mask design team to implement layout views of designs.

Minimum Qualifications

  • BS and 3+ years of relevant industry experience required.
