Full Job Description
Principal Audio/DSP Systems Engineer

Responsibilities:
  • Architect and optimize end-to-end deployment pipelines for compact audio AI models from trained model through quantization, profiling, and production deployment on DSP/NPU targets
  • Define and drive DSP/NPU partitioning strategies, balancing workload allocation, memory bandwidth, latency, and power across processing elements on the SoC
  • Own simulation-to-RTL validation flows: develop bit-exact reference models, collaborate with RTL teams on functional verification, and close gaps between algorithmic intent and hardware behavior
  • Perform low-level implementation and optimization of signal processing and neural network kernels for fixed-point DSP and NPU instruction sets, maximizing utilization of MAC arrays, SIMD paths, and on-chip memory hierarchies
  • Profile and optimize inference performance (cycles, memory footprint, power) under strict always-on and real-time constraints typical of hearable/wearable devices
  • Design and maintain model compression and quantization workflows (PTQ, QAT) with rigorous quality tracking against floating-point baselines
  • Develop signal processing algorithms for array processing, beamforming, and spatial filtering, with a clear path from MATLAB/Python prototypes to deployable fixed-point implementations
  • Contribute to audio ASIC system architecture definition - informing hardware spec decisions (precision, buffer sizes, DMA structures, NPU config) based on algorithmic and deployment requirements
  • Generate IP (patents) and represent the team's technical depth to OEM customers in automotive and hearable segments
  • Mentor engineers in deployment best practices, embedded optimization, and hardware-aware algorithm design


Required Qualifications:
  • PhD in Electrical Engineering, signal processing, or related field
  • 10+ years in audio/speech signal processing within a semiconductor environment, with significant hands-on deployment experience on DSP and/or NPU platforms
  • Demonstrated expertise in fixed-point algorithm implementation, model quantization (PTQ/QAT), and cycle-level optimization for resource-constrained processors
  • Strong working knowledge of simulation-to-RTL flows: bit-exact modeling, RTL co-simulation, and functional verification collaboration with design teams
  • Proficiency in C (embedded/firmware level), 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 inference
  • Solid foundation in array signal processing, beamforming, and acoustic system design


Preferred Qualifications:
  • Direct experience with NPU/accelerator architectures (dataflow engines, weight-stationary/output-stationary designs) and their programming models
  • Familiarity with ASIC development cycles - from algorithm freeze through tapeout and silicon validation
  • Background in always-on, sub-mW audio processing for hearable, TWS, or wearable products
  • Track record of US patents in audio signal processing or embedded ML
  • Experience technically leading a small engineering team
