Summary
About us
Software teams at Dyson are highly collaborative and have strong autonomy. Dyson is looking for a self-driven Audio DSP engineer to design, build and debug end-to end audio paths, delivering audio quality and reliability, as part of the team developing the next generation of wireless audio experience and personal device connectivity.
About the role
This is a senior level individual contributor to help build audio processing capabilities in Bluetooth audio layer and interface with audio infrastructure and other media stacks. Responsible for engaging various cross functional teams and an integral part of a small team of engineers delivering wireless audio features.
This position will require advanced skills in Matlab and extensive research in audio processing and proven knowledge of advanced audio coding standards.
You will have the opportunity to work with and improve upon a variety of exciting technologies like audio playback processing, voice pickup and speech processing, as well as designing control algorithms to suppress internal and external sound in active noise-cancelling (ANC) headphones. Because our teams are small, we are looking for self-directed, collaborative, and flexible candidates who can wear several hats.
This position is a fantastic opportunity for a self-starter who wants to make a significant impact on the future of our product lines.
Responsibilities
Support and influence audio and electronics architectural teams.
Evaluate audio signalling chains through state-of-the-art BT SOC and ANC devices, optimising each different audio mode, codec type and noise performance.
Specify and develop with 3rd parties, telephony speech algorithms for integration into the audio sub-system, ensuring performance in both narrow and wideband telephony meets international standards and that all API’s and adjustable parameters are fully specified. Support integration of multi-microphone directional beam forming noise reduction.
Identify, develop, and integrate other DSP capabilities within the audio DSP sub-system.
Design, implement and test algorithms to solve technical challenges for new wearable audio products.
Demonstrate and deliver new benefits for our customers using innovative technologies and novel applications of technologies like Active Noise Reduction, Spatial Audio, Voice pickup and Bluetooth communications.
Voice capture technology DSP algorithm development, tuning and evaluation on wearable products.
Investigate, design, and create testing methodologies to ensure the best voice performance in the industry.
Collaborate with a diverse team of Acoustics, System and DSP engineers on the next generation of wearable devices.
About you
Demonstrated expertise in embedded Audio DSP for consumer products.
Demonstrated experience in audio and speech processing, including time-domain and frequency-domain based signal processing.
Proficient in digital signal processing related theories.
Background in audio processing and/or audio routing/transport, including audio encoding/decoding, packetization, compression and basic audio manipulation (e.g., sample rate conversion, FIR/IIR filters, basic transforms, etc).
Demonstrable expertise in programming signal processing algorithms using high-level languages like C/C++, Python and Matlab as well as low-level languages like fixed-point assembly to facilitate the implementation of audio processing algorithms.
Low level debugging experience.
Experience of communications protocols such Bluetooth Classic and BTLE Audio.
Knowledge in microphone arrays, adaptive beamformers, echo cancellation and noise suppression.
Exposure to acoustics and acoustic measurements to facilitate the collecting of audio data from human participants to help validate the product performance in real life environments.
Expertise with basic audio lab equipment as well as knowledge and exposure to basic hardware design.
Ability to evaluate and integrate 3rd party algorithms and perform "make vs. buy" analysis.
Experience with Bluetooth audio products and an understanding of their advantages and limitations.
Experience with or understanding of acoustic transducers such as microphones, micro-speakers, and loudspeakers.
Experience of hardware interfaces such as I2C, I2S and USB
Effective communication skills including the ability to discuss complex technical issues with experts in other fields.
