TL;DR · Machine Learning Scientist, GenAI & ML Frameworks

Machine Learning Scientist - Apple Services Engineering, GenAI & ML Frameworks joins the GenAI & ML Frameworks team to bridge foundation model capabilities with real-world production systems. This role involves end-to-end development across LLM training, including domain-adaptive continual pretraining, post-training, and preference optimization using GRPO-style methods. The candidate will build agentic systems featuring tool schemas and multi-turn reliability while performing deployment-aware optimizations for latency, cost, and reliability. Key responsibilities include developing tools for synthetic data generation, evaluation harnesses, and training pipelines to improve LLM domain knowledge and reasoning. Required skills include proficiency in Python and deep learning toolkits such as Jax, TensorFlow, or PyTorch. The role focuses on the technical challenge of integrating large language models into user-facing features by solving problems related to system integration and production readiness across various cross-LOB initiatives.

What you'll do

  • Perform LLM continual pretraining, post-training, and preference optimization using RL methods like GRPO.
  • Develop agentic systems focusing on tool schemas, multi-turn reliability, and verifier-based learning loops.
  • Optimize models for production by balancing latency, cost, and reliability trade-offs.
  • Build robust tooling for synthetic data generation, evaluation harnesses, and training pipelines.
  • Translate LLM research into shipped features across various Apple Services products.
  • Lead cross-functional initiatives from initial problem definition through execution and scaling.
  • Improve LLM domain knowledge, tool use, reasoning, and system integration.

What we're looking for

  • BS/MS or PhD in a quantitative field such as Computer Science, Mathematics, Statistics, or Physics.
  • Proficient programming skills in Python.
  • Hands-on experience with deep learning toolkits including Jax, TensorFlow, or PyTorch.
  • Proven track record in training and deploying large models or building large-scale distributed systems.
  • Deep understanding of Deep Learning and Large Language Models (LLMs).
  • Expertise in Natural Language Processing.
  • Experience in LLM training techniques like continual pretraining, post-training, and preference optimization.
  • Experience with agentic systems, including tool schemas, multi-turn reliability, and synthetic data generation.
