Lead Natural Language Modeling Research Scientist, Siri Speech

full-timePosted: Oct 31, 2025

Job Description

Are you excited about Generative AI and Large Language Models? Are you interested in working on cutting edge generative modeling technologies and its application to virtual assistants to enrich billions of people!? Join the SWE Response team at Apple! We are looking for an exceptional senior research scientist experienced in design and development of training, adapting and deploying large scale ML models with a focus on natural language understanding, generation, speech and/or multimodal generation. Additionally, you’ll advance and apply the latest ML techniques to Apple’s virtual assistant and dive into the details to craft the Siri experience for millions of users worldwide. We are seeking a lead scientist candidate with a proven track record in applied ML research who is not only capable of hands-on work but also leading projects. Responsibilities in the role will include training large scale language and multimodal models on distributed backends, deployment of compact neural architectures such as transformers efficiently on device, and learning policies that can be personalized to the user in a privacy preserving manner. Ensuring quality with an emphasis on fairness and model robustness would constitute an important part of the role. You will be interacting very closely with a variety of ML researchers, software engineers, hardware & design teams cross functionally. Your primary responsibilities will center on enriching conversation understanding capabilities through LLM and multimodal models. The user experience initiative would focus on enriching system safety experience.
