Embedded Software Engineer - Reality Labs Research

At Reality Labs Research (RL-R), our goal is to explore, innovate and design novel interfaces and hardware subsystems for the next generation of virtual, augmented, and mixed reality experiences. We are looking for a skilled Embedded Software Engineer to join our team, whose mission is to design, build, and test prototype systems for future consumer wearable experiences. You will have a broad set of experiences, quickly solve problems, generate big ideas, work in new technology areas, and drive concepts into prototypes. You will work with a diverse and highly interdisciplinary team of researchers and engineers and will have access to cutting edge technology, resources, and testing facilities.You will collaborate and contribute at a technical level and guide the efforts of team members who will support you. You will be part of the team working on hardware design, bring-up, debugging, and supporting the end users of your work. We are looking for someone who embraces ambiguity, has a sense of ownership for the work, and proven experience with design-build-test cycles at medium scale. We have many problems that need solutions, and we depend on demonstrated experience of resourcefulness and pivoting based on changing situations for both short and long term problem solving.

• Contribute effort to analyze, design, develop, and debug firmware, and embedded software including sensing and imaging systems
• Understand and implement firmware on micro-controllers and SoCs, leverage peripherals, manage power consumption, support boot loaders, and schedule real-time tasks (RTOS).
• Collaborate in a team environment across multiple, research focused, and engineering disciplines, making the architectural tradeoffs required to rapidly deliver firmware solutions.
• Support all phases of custom hardware and research test-vehicle development - including early architecture requirements definition, firmware and embedded system architecture, proof-of-concept implementation, selection of MCUs and tools, and board bring-up.
• Understand and drive implementation of embedded SW development best practices across teams and projects, including setting expectations, defining backlog, and tracking progress of contingent staff.
• Document and communicate learning, understanding, and problem solving to a wide range of audiences and disciplines.
• Interact closely with firmware, software and hardware teams both project specific and cross functional to ensure that the platforms we are building will work well with other systems.

• B.S. degree in Computer Science, Electrical Engineering, or equivalent experience
• 6+ years of experience in embedded software development
• Experienced in use of the C language for development, debugging, performance analysis, and testing of embedded software and firmware
• Experience with embedded micro-controllers such as ARM Cortex M0/M3/M4 architecture and their boot mechanisms
• Experience with peripherals such as USB, SPI, MIPI CSI/DSI, I2C, UART, GPIO, etc., coding and modifying peripheral device drivers, and using peripheral DMA and interrupt controller programming for peripherals
• Experience in the use of oscilloscopes, logic analyzers and protocol decoders

• Experience with standard protocols such as USB device classes (e.g. UVC, UAC, or HID) or Bluetooth LE GATT services
• Experience with some embedded Linux frameworks like kconfig, devicetree, Android, Yocto, Buildroot
• Experience maximizing performance of resource constrained systems
• Experience integrating novel algorithms into either an RTOS-based or bare-metal system
• Experience with accelerators(e.g. DSP, image processors, or Tensor/AI cores) and DMA engines
