Edge AI Researcher (Speech & Audio Models)

We are seeking an Edge AI Research Scientist to develop next-generation speech and audio AI systems that run efficiently on smartphones, wearables, and other resource-constrained devices. This role sits at the intersection of machine learning research, systems optimization, and production engineering. You will design compact model architectures, develop advanced compression techniques, and optimize inference pipelines that enable real-time speech AI experiences directly on end-user devices. You will work across a broad range of voice technologies, including automatic speech recognition (ASR), text-to-speech (TTS), speech translation, speech-to-speech systems, and neural audio codecs. The ideal candidate combines strong research credentials with hands-on implementation skills and has a deep understanding of efficient deep learning, model optimization, and hardware-aware machine learning. What You'll Do Research and Model Development Drive research in efficient machine learning and edge AI for speech and audio applications. Design compact model architectures capable of operating under strict latency, memory, and power constraints. Develop and improve state-of-the-art approaches for: Low-rank adaptation and compression Hardware-aware architectures Efficient training and inference techniques Contribute to speech-to-speech, speech recognition, speech translation, text-to-speech, and audio generation systems. Inference Optimization Build highly optimized inference pipelines for mobile and embedded hardware. Improve performance across CPUs, GPUs, NPUs, and other acceleration hardware. Optimize: Operator execution Scheduling strategies Caching mechanisms End-to-end system latency Integrate models with production runtimes and deployment frameworks. Performance Evaluation Develop rigorous benchmarking methodologies for edge AI systems. Measure and improve: Real-time factor Time-to-first-audio Thermal behavior Speech quality and accuracy Validate performance directly on target devices rather than relying solely on simulator environments. Cross-Functional Collaboration Partner with machine learning researchers, mobile engineers, and systems engineers to bring research into production. Translate research prototypes into scalable products and customer-facing technologies. Communicate findings through internal documentation, technical publications, conference papers, and open-source contributions where appropriate. Required Qualifications Master's degree, Ph.D., or equivalent industry experience in: Computer Science Efficient Deep Learning Demonstrated expertise in model compression, efficient inference, or edge AI through research publications, production systems, or both. Strong understanding of one or more of the following: Hardware-aware optimization Strong software engineering skills with: PyTorch or JAX C/C++ or equivalent systems-level programming experience Experience optimizing neural networks for resource-constrained hardware. Practical knowledge of: GPUs NPUs Memory systems Numerical precision tradeoffs Ability to make informed tradeoffs between model quality, latency, memory footprint, power consumption, and deployment portability. Professional proficiency in English. Ability to thrive in a fast-moving, research-driven environment. Preferred Qualifications Experience working with: Automatic Speech Recognition (ASR) Speech-to-Speech Models Familiarity with deployment frameworks such as: Core ML ExecuTorch ONNX Runtime LiteRT / TensorFlow Lite TensorRT Experience with acceleration technologies including: Metal Vulkan CUDA QNN
