Sr Machine Learning Engineer, Proactive

Sourced from themuse.com

Apple is seeking a Senior Machine Learning Engineer to build next-generation intelligent search and AI experiences. You will design, train, fine-tune, and deploy large language models, semantic retrieval systems, and ranking models for on-device deployment. The role involves optimizing models for efficiency and privacy while partnering with cross-functional teams to bring AI capabilities from research to production.

• Build semantic retrieval, embedding, reranking, and retrieval-augmented generation systems.
• Design, train, fine-tune, distill, and optimize transformer-based language models and foundation models for on-device deployment.
• Develop LLM fine-tuning and post-training approaches, including supervised fine-tuning, instruction tuning, preference optimization, and parameter-efficient fine-tuning.
• Research and prototype on-device generative AI techniques such as knowledge distillation, model compression, quantization, and pruning.
• Analyze search relevance and user behavior to design evaluation methodologies and metrics.
• Build scalable experimentation and evaluation pipelines for LLMs and search models.
• Partner with engineers, researchers, product managers, and designers to bring AI capabilities to production.
