Your role

We are looking for an AI/ML Speech Algorithm Engineer who will join our Audio AI team to work on cutting-edge speech AI technologies for hearables, contributing across the full research-to-productization pipeline — from exploring novel architectures and proof-of-concept work through productization and deployment on resource-constrained wearable devices.

Main responsibilities:

• 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.

Main requirements:

• 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.

Our Diversity, Equity and Inclusion commitment​

We are committed to creating an inclusive environment for all employees. We celebrate diversity and provide equal opportunities to all, regardless of race, gender, ethnicity, religion, disability, sexual orientation, or any other characteristic that makes us unique.
