Foundation Models RL Research Engineer – Agentic Reasoning

Apple Inc.; Zürich; Vor Ort; CHF 180.000 - 240.000; Vollzeit

Zusammenfassung

Apple Inc. in Zurich seeks a Machine Learning Engineer specializing in foundation model post-training. You will advance RL for agentic tool use, planning and reasoning to enhance Apple’s foundation models and influence Siri and other features.

You will collaborate with a Europe-based team of RL/ML experts and work closely with Apple’s U.S. foundation model groups, contributing to both scientific progress and practical improvements.

Qualifikationen

• MSc, PhD, or equivalent in Computer Science, ML, Electrical Engineering, or related field.
• Strong background in reinforcement learning and deep learning, with hands-on experience training large-scale models.
• Proficiency in Python and ML frameworks (PyTorch, JAX), with distributed training experience.
• Ability to collaborate in interdisciplinary teams and clearly communicate complex concepts to both technical and non-technical partners.

Aufgaben

• Develop and scale RL methods to improve reasoning, instruction following, multi-turn dialogue, and reduce hallucinations in large language models.
• Design and train agents with tool use, planning, and API integration to reliably accomplish tasks.
• Build and refine reward models, evaluators, datasets, and simulation environments for RLHF, RLAIF, and RLVF.
• Run large-scale experiments, analyze results, and translate findings into research contributions and practical improvements for Apple Intelligence.
