It takes the right data, careful evaluation, models built for each locale, and systems that can do all of this across many markets at once.\nThe Global Siri team builds the next generation of Siri's AI agents for users around the world. We're looking for a strong AI engineer who works across the whole ML lifecycle (data, modeling, evaluation, and deployment) and uses agentic tools every day to get more productive to make Siri great in every language.\nDescription\nAs an applied AI Engineer on Global Siri, you'll work closely with Siri's modeling, evaluation, data science, and deployment teams. You'll also partner with Apple's Modeling, ML platform, and safety teams. You'll design, build, and ship the data, models, and systems that bring Siri's AI features to new languages and markets and keep raising quality in the markets we already serve.\nMinimum Qualifications\nB.S. or M.S. in Computer Science or a related field, or equivalent experience\nStrong software engineering fundamentals and proficiency in Python\nHands-on experience across the ML lifecycle (data, training, evaluation, deployment).\nStrong understanding of LLM, NLP, ML and their application.\nHands-on experience with ASR, acoustic triggering, or TTS in international locales, including accents, code-switching, low-resource languages, and locale-specific metrics\nExtensive hands-on experience with agentic AI-assisted coding and context engineering\nAn analytical, data-driven mindset and experience.\nExperience building and debugging production services or data products end to end\nExcellent communication skills and the ability to work across teams in an English-speaking environment\nStrong written and verbal communication skills\nPreferred Qualifications\nAgentic coding and GenAI as your daily way of working, including building your own agents or workflows that automate real engineering and data tasks\nExperience building synthetic data generation pipelines and using them to launch features or improve product metrics, especially where real data is scarce\nExperience with large-scale data or ML infrastructure (e.g. Spark, Kubernetes) and LLM evaluation, such as LLM-as-judge\nA track record of shipping user-facing ML features in multiple languages or markets","description_format":"text","description_chars":2412,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[{"language":"English","level":"All
