About the role
The Multimedia Audio Systems team develops and commercializes speech enhancement models on embedded platforms such as HiFi, Hexagon DSP, and ARM. The work covers signal processing and neural network algorithms for voice and audio applications including echo cancellation, noise suppression, and target source separation across mobile, compute, XR/AR/VR, IoT, and wearable devices. This role implements and optimizes audio algorithms and NN workloads, collaborates with cross-functional teams, and supports commercialization.
What you will do
- Develop and optimize advanced audio signal processing algorithms such as adaptive filtering algorithms for echo cancellation and Noise Suppression.
- Implementation and Optimization of NN workloads on the DSP and ARM with HW acceleration on ARM (Neon/SME) and NPU (Neural Processing Unit)
- Collaborate with Cross functional teams to integrate audio solutions into diverse product lines
- Support debugging, tuning, and troubleshooting algorithm performance issues for commercialized solutions.
- Participate in the full product development lifecycle, from concept to commercialization.
Skills used in this role
What the employer is looking for
- Experience developing and optimizing neural network (NN) workloads on any digital signal processor (DSP) architectures such as HiFi, Hexagon, or ARM/MCU
- Experience working with neural network (NN) frameworks and runtimes such as LiteRT/TensorFlow Lite (TFLite), Open Neural Network Exchange Runtime (ONNX Runtime), TensorFlow Lite for Microcontrollers (TFLM), Qualcomm Neural Network (QNN), or Qualcomm AI Runtime (QAIRT).
- Experience using neural network (NN) optimized libraries and extensions such as HiFi NN extensions, Nature DSP, XNNPACK, CMSIS-NN, or Hexagon NN (HexNN).
- Experience converting MATLAB algorithms into platform code, such as embedded C.
- Knowledge of fixed-point programming.
