RF Systems Engineer at Facebook AR/VR, you will develop new wireless systems for Augmented Reality (AR). You will work closely with product design, electrical and firmware engineers on advancing the state of AR through research and development, prototyping, and implementation in shipping products. You will own RF system design from initial definition through production. You should have deep experience in consumer electronics (CE) development and wireless technology along with a passion for exploration and experimentation.RESPONSIBILITIES

  • Deliver high performance wireless solutions at optimal BOM costs at low power balanced with appropriate throughput
  • Drive invention and evolution of RF wireless systems to enable incredible experiences for future products
  • Provide guidance and leadership to RF design activities for internal and external teams
  • Perform multi-radio coexistence mitigation (including RF link budget planning and issue debugging)
  • Perform simulations for RF design and desense mitigation (3D EM and circuit level simulations)
  • Characterize and debug desense and EMI issues to meet requirements
  • Work with antenna design and test vendors to ensure the quality of the overall system design
  • Work closely with internal and external cross-functional teams to ensure meets the specs at the component, board, and system level
  • Design and execute a test methodology for characterizing system performance with external partners and test houses
  • Take the product through development, compliance testing, operator testing

MINIMUM QUALIFICATIONS

  • 10+ years of experience with design for small form factor designs close to the human body like cell phones, wearables, and tablets
