Machine Learning Engineer - Applied Science

As a member of our high-impact, iterative environment, you'll have the unique and rewarding opportunity to shape upcoming products from Apple. Our team includes a diversity of backgrounds from applied scientists with a focus in NLP to experienced distributed systems engineers. We are looking for candidates with both applied machine learning and deep-learning experience as well as strong engineering skills. Minimum Qualifications You have 8+ years of experience in information retrieval, natural language processing, machine learning, or deep learning. You have a deep understanding of machine learning theory, including supervised learning, ranking models, embeddings, representation learning, and evaluation metrics. You have proven ability to apply advanced ML techniques to improve search relevance and retrieval quality at scale. You are comfortable leading experimentation, offline evaluation, and online A/B testing for iterative improvements in search quality. You actively monitor recent research literature — including arXiv, NeurIPS, ICML, ACL, SIGIR, and industry publications — and have a track record of translating findings into practical system improvements. You independently identify high-impact research directions and drive them forward without requiring top-down direction. You demonstrate a strong bias toward action, moving fluidly from paper to prototype to production in tight iteration cycles — executing quickly while maintaining quality and rigor. You have excellent interpersonal skills, the ability to work independently as well as part of a team, including cross-functional collaboration with product and design. You have a Master's Degree in Computer Science, Machine Learning, or a related field, or equivalent practical experience. Preferred Qualifications PhD in Computer Science, Machine Learning, Information Retrieval, or a related field, or equivalent research experience demonstrated through publications, patents, or significant open-source contributions. Track record of publishing or presenting at top-tier research venues such as NeurIPS, ICML, ACL, SIGIR, WWW, or equivalent. Experience applying LLMs and generative AI techniques to production search or recommendation systems.
