AI/ML Speech Algorithm Engineer (F/M)

• Contribute to speech AI algorithms end to end - speech enhancement, acoustic feedback cancellation, beamforming, acoustic scene recognition - from architecture exploration through to a verified feature on a shipping device.
• Design, train and evaluate deep learning architectures against hard real-time latency, MIPS and footprint budgets, incorporating quantization, pruning and other model optimization techniques for deployment.
• Build out the evaluation stack: objective and perceptual metrics, listening tests with audiology colleagues, and regression testing to verify model improvements.
• Generate and curate the data the models need - noise corpora, room impulse responses and acoustic simulation, multi-microphone and binaural recordings.
• Contribute reusable training and testing infrastructure across tasks.

• MSc or PhD in Electrical Engineering, Computer Science or a related STEM field, with real depth in deep learning and signal processing (a BSc with equivalent demonstrated depth also works).
• 5+ years building audio or speech ML algorithms, including at least one algorithm personally carried from research into a shipped product.
• Hands-on model development and production experience in Python, with PyTorch or TensorFlow.
• Track record of deploying models to real-time or embedded targets under latency, memory and compute constraints, iterating on the basis of measurements rather than intuition.
• (Preferred) Hearing-aid-class signal processing, or experience with hearables and wearable audio products.
• (Preferred) End-to-end audio system understanding: transducers, microphones, audio ICs, acoustics, embedded DSPs and NPUs.
• (Preferred) Familiarity with model optimization techniques - quantization-aware training, pruning, knowledge distillation, and other methods for compressing models without sacrificing performance.
• (Preferred) Cloud-based training environments (GCP or equivalent) and experience with GPU cluster workflows.
• (Preferred) Exposure to regulated or medical-device product development.
• (Preferred) Publications or patents in speech, audio or applied deep learning.
