Summary（岗位介绍）

Facebook Reality Labs (FRL) focuses on connecting people through Virtual Reality (VR) and Augmented Reality (AR). The compute performance and power efficiency requirements of these products require custom silicon. The Facebook Agile Silicon Team (FAST) is driving the state of the art forward with breakthroughs in computer vision, machine learning, mixed reality, graphics, displays, sensors, and new ways to map the human body. We believe the only way to achieve our goals is to look at the entire stack, from transistor, through architecture, to firmware, and algorithms.

We are seeking an Embedded DSP Engineer who is excited about introducing groundbreaking capabilities in the fields of computer vision (CV), machine learning (ML), and imaging (ISP), through mapping and optimization of complex imaging and embedded algorithms to custom DSPs and accelerators. The successful candidate will be required to code optimized kernels and libraries from high to low-level for current and future in-house heterogeneous compute and vision platforms, as well as architecting new methodologies that assist in analyzing, profiling and optimizing memory footprint, runtime performance, and power consumption of such workloads. They will also have the opportunity to contribute in defining architectural requirements by working with multidisciplinary teams and providing detailed design specifications of such compute platforms.

Qualifications（岗位要求）

Bachelors in electrical electronics, computer science or equivalent relevant experience.

Experience with low-level SW optimization at instruction level, loop optimization, vectorization, data organization and caching. Programming SIMD, VLIW, and/or Vector processors.

Knowledge of ML, CNN accelerators and their architectural design trade-offs.

5+ years experience designing and implementing complex real-time systems using C/C++ for embedded processors.

Description（岗位职责）

Code CV, ML, imaging algorithms on customized processors, and accelerators in C and/or C++ for performance, latency, power, and memory.

Perform low-level SW optimization at instruction level by loop optimization, vectorization, pipelining, data layout re-organization and cache/memory management.

Study state of the art algorithms in the field of CV, ML and Imaging, to develop appropriate SW-HW partitioning.

Influence algorithm and application optimizations in the context of low-power edge devices, including numerics, hardware-aware ML models, pruning etc.

Additional Requirements（额外要求）

MS or Ph.D. in EE/CS.

Theoretical knowledge in the field of computer vision, machine learning, and image processing, or ISP sensors.

Experience in development of imaging and CV or related signal processing algorithms (e.g. OpenCV, Eigen, Halide, Game physics and 3D graphics, CODECs, or Communication).

Experience with methods for partitioning a solution across hardware and software, and other multi-disciplinary boundaries in a system solution.

Familiarity with profiling and code optimization tooling and methodology or any domain-specific compiler experience. Familiarity with modern ML compiler stacks like GLOW, TVM, XLA etc.

Familiarity with ML frameworks like Pytorch/Tensorflow and model optimization toolkits.
