Job Description:

Facebook Reality Labs is a world leader in the design of virtual reality (VR) and augmented reality (AR) systems. Come work alongside technology visionaries and research scientists to create the technology that makes VR and AR pervasive and universal. The Cameras & Sensors (C&S) team gathers world class expertise and talent in photographic and machine vision cameras, imaging sensors, and depth, inertial, and bio sensing systems, and owns the development and validation for all these sensing systems across the whole AR, VR, & Portal product portfolios. We are looking for an Analog Mixed Signal Designer to create innovative designs at the forefront of custom sensor technology, to enable breakthrough new depth sensing architectures delivering the best-in-class performance in small form factors and ultra-low power systems. The ideal candidate is enthusiastic about exploring and tackling new on-sensor compute architectures and sometimes ambiguous technical challenges, is engaged in deep collaboration across internal and external teams of passionate technologists that result in detailed depth sensor analyses, critical tradeoff evaluations, and sensor architectural execution strategies.The scope of this role in the depth system architecture team will be a technical lead in creating, specifying, and reviewing new approaches to achieve high-end depth system performance in very constrained area and power efficiency requirements in the AR and VR space.

Analog/Mixed Signal (AMS) Design Engineer Responsibilities:

  • Explore, propose, and create innovation high-performance depth sensor architecture proposals within stringent area and power efficiency constraints, targeting Facebook's leading-edge AR and VR devices
  • Draft and own detailed specification documentation for internal and external partners
  • Participate in and drive deep technical weekly reviews with key external design partners, from top level architecture, critical blocks, functional models, and RTL
  • Work closely with internal and external teams of circuit and logic designers to design through RTL, schematics, and models
  • Run simulations to predict system performance and power, and validate functionality
  • Close collaboration with chip and block architects to understand macro floorplan, power distribution, and signal interfaces
  • Develop scripts as necessary to improve productivity and reliability
  • Participate in process improvements and complete any assigned circuit design task with minimal supervision
  • Travel both domestically and internationally up to 10% of the time

    Minimum Qualifications:
    • Familiar with CMOS image processing, depth performance analysis, imaging algorithms.
    • Understanding of mixed-signal building blocks (ADCs, DACs, output drivers), and DLL/PLL.
    • Experience in circuit simulation and modeling, using Cadence, Mentor, and Synopsis tools.
    • 3+ years of experience with analog circuit design and feedback control systems.
    • Experience in programming/scripting with HDL (Verilog/VHDL/SystemVerilog), MATLAB, Python.
    • Experience communicating clearly and working effectively in a collaborative team.
    • Ph.D. in Electrical Engineering, Computer Science, or related field or equivalent practical experience. Degree must be completed prior to joining Meta.
    • Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience.

      Preferred Qualifications:
      • Knowledge of IC fabrication processes and device physics
      • Understanding the basics of SPAD depth sensor, including PLL/DLL/TDC and depth signal processing
      • Experience in prototyping, characterization and debugging of image/depth sensor IC
      • Experience publications in peer reviewed journals and conferences
