Job Description

Facebook is the world leader in the design of virtual and augmented reality systems. Come work alongside expert engineers and research scientists to create the technology that makes AR and VR pervasive and universal. Join the adventure of a lifetime as we make science fiction real and change the world. You're a Firmware Engineer with deep embedded system knowledge, a passion for working on new hardware and strong technical leadership skills. You're comfortable working with a wide variety of hardware devices, working with a team to rapidly deliver reliable high performance firmware. At the Facebook AR/VR team, you will design, build and test firmware systems for future Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) experiences. You will join a world-class team of experts exploring new AR/VR concepts through rapid prototyping. Firmware for AR/VR systems spans multiple target classes, requiring deep collaboration across engineering disciplines (electrical, mechanical, optical, firmware and software) and directly impacting user immersion. We're looking for people who quickly solve problems, generate big ideas, work in new technology areas, drive concepts into prototypes, and envision how those prototypes transition to high-volume consumer products. In this role, you are expected to participate in the definition of architecture and implementation of FW/middleware architecture in the research arena, as well as support rapid prototyping efforts led by a team of mixed-discipline researchers and engineers.

RESPONSIBILITIES

* Analyze, design, develop, and debug firmware for a wide variety of AR and VR devices, including novel sensing and imaging systems, haptic devices, input devices, and audio prototypes



Understand and implement power-management, boot loaders, scheduling, and RTOS

Collaborate in a team environment across multiple , product focused, research, and engineering disciplines, making the architectural tradeoffs required to rapidly deliver firmware solutions

Support custom silicon development on an as-needed basis, including early architecture requirements definition, FPGA/ASIC development, firmware architecture, implementation, simulation, debug, and chip bring up, and provide support to systems and software teams

Understand and drive implementation of FW development "good practices" across teams and projects

MINIMUM QUALIFICATIONS

* B.S./M.S. degree in Computer Science or Electrical Engineering or equivalent experience



5+ years of experience in embedded firmware design

Experience producing production quality, fail-safe firmware for low-power real-time system control

Experience with hardware, clock-level issues, bridges, delays, interrupts, clock gating, polling etc.

Experience implementing firmware for low-power SoC and MCU

Experience with wireless and wired communication protocols, including USB, TCP/IP, Ethernet, Bluetooth and 802.11

Experience with embedded micro-controllers like ARM Cortex M0/M3/M4 architecture and boot mechanism, interrupt priorities and experience with configuring peripherals

Experience analyzing hardware and power consumption

Experience with software design and programming in C/C++ for development, debugging, testing and performance analysis

Experience with device drivers/middleware, and an understanding of the entire HW/firmware/driver/OS/application stack

Experience with Linux/Unix

Experience with instrumentation like oscilloscopes, logic/protocol analyzers for debugging embedded systems at HW level

Experience with support software such as MATLAB, Python, Perl, and Lua

Experience with device documentation and translate that information into software solutions

Experience with methods of designing experiments to diagnose embedded hardware and firmware problems

Experience with cross multi-disciplinary boundaries to drive system solutions

Experience with working independently and managing priorities

PREFERRED QUALIFICATIONS

* Experience with peripherals such as USB, SPI, MIPI CSI/DSI, I2C, UART, GPIO etc.



Experience with protocol implementations such as USB device classes (UVC, UAC, HID)

Experience with a variety of vendor specific hardware evaluation boards

Experience in real-time processing for user interaction tasks

Experience with embedded Linux distributions
