Summary（岗位介绍）
Reality Labs - Research brings together scientists, engineers, and technologists to create the future of virtual and augmented reality. The Audio Research team is focused on harnessing the power of AR and VR to make virtual sounds indistinguishable from reality, and make hearing and communication easier for billions of people at all levels of hearing ability. We’re looking for an Audio DSP Engineer to join our interdisciplinary team. We work to solve problems at the intersection of digital signal processing, machine learning, acoustics, hearing sciences, auditory perception, and multimodal interaction. In this position, your focus will be designing, prototyping, and maturing systems and algorithms to solve challenges in AR audio. By demonstrating new experiences and new audio technologies not yet found in consumer devices, these efforts ultimately aim to introduce these experiences and technologies to Meta’s AR and VR products.
Qualifications（岗位要求）
Master’s degree in a relevant field such as electrical engineering, digital audio, acoustics, and 2+ years of industry experience in real-time audio signal processing, or equivalent combination of education and experience
2+ years of experience in designing audio algorithms for consumer devices (e.g. microphone array processing, spatial audio rendering, active noise cancellation, echo cancellation, noise suppression, multi-band compression, adaptive filtering, speaker protection)
Experience implementing real-time audio processing algorithms in prototypes or products using systems or hardware languages such as C/C++
Proficiency in MATLAB or another prototyping framework
Understanding of DSP fundamentals including the experience to explain 1) properties of linear and time invariant systems, 2) the mathematical structure of and implementation strategies for IIR and FIR filters, and 3) standard methods for system identification and adaptive filters
Description（岗位职责）
Design and implement real-time DSP- and ML-based end-to-end integrated audio processing pipelines (e.g. for applications such as communications, hearing correction, and speech recognition input, and others)
Design and implement real-time DSP- and ML-based audio processing components (e.g. beamforming, noise reduction, dynamic range compression, spatialization, and others)
Translate audio processing implemented in MATLAB or other prototyping frameworks into real-time code for embedded systems
Contribute to the development of requirements specifications for embedded real-time audio processing systems
Influence the direction of research to accommodate the needs of specific embedded systems and target use cases
Additional Requirements（额外要求）
PhD in Electrical Engineering, Computer Science, or related field, with audio signal processing as the research topic
Experience working in an interdisciplinary team, such as with algorithm researchers, user experience researchers, audio systems engineers, and others
Experience applying ML to audio processing problems
Experience building software architectures for signal processing systems
Experience in optimizing algorithm performance by leveraging hardware accelerators
Understanding of DSP hardware architecture including instruction set architectures, memory hierarchy, buses and interconnects
Experience in designing or programming for a custom DSP microarchitecture, for example: experience with Verilog, VHDL, or assembly in a custom DSP project
