Principal Audio/DSP Systems Engineer

Responsibilities

• Architect and optimize end-to-end deployment pipelines for compact audio AI models, including quantization, profiling, and production deployment on DSP/NPU targets
• Define DSP/NPU partitioning strategies to balance workload, memory bandwidth, latency, and power across SoC processing elements
• Own simulation-to-RTL validation flows by developing bit-exact reference models and collaborating with RTL teams on functional verification
• Perform low-level implementation and optimization of signal processing and neural network kernels for fixed-point DSP and NPU instruction sets
• Profile and optimize inference performance under strict always-on and real-time constraints for hearable and wearable devices
• Design and maintain model compression and quantization workflows (PTQ, QAT) with rigorous quality tracking
• Develop signal processing algorithms for array processing, beamforming, and spatial filtering
• Contribute to audio ASIC system architecture definition and mentor engineers in embedded optimization and hardware-aware design

Requirements

• PhD in Electrical Engineering, signal processing, or a related field
• 10+ years of experience in audio/speech signal processing within a semiconductor environment
• Expertise in fixed-point algorithm implementation, model quantization (PTQ/QAT), and cycle-level optimization
• Strong knowledge of simulation-to-RTL flows, including bit-exact modeling and RTL co-simulation
• Proficiency in C (embedded/firmware), Python, MATLAB, and deep learning frameworks (TensorFlow/TFLite, PyTorch/ONNX)
• Experience with low-level profiling tools, instruction set architectures, and memory optimization for embedded AI

Preferred Qualifications

• Direct experience with NPU/accelerator architectures and their programming models
• Familiarity with ASIC development cycles from algorithm freeze through silicon validation
• Background in always-on, sub-mW audio processing for hearable or wearable products
• Track record of US patents in audio signal processing or embedded ML
• Experience technically leading small engineering teams
