Role Number: 200612111

Our Siri team is developing groundbreaking technology at the intersection of large-scale systems, spoken language, machine learning, and LLMs in pursuit of a unique challenge: building a conversational agent that is not only helpful and knowledgeable but can also get things done naturally, intelligently, and delightfully, at the level of quality that Apple’s customers have come to expect. The ML SEE team powers the rapid iteration loop for Siri ML and software engineers. We build large-scale evaluation solutions for Apple’s latest language models and Siri's overall customer experience.

Description

In this Technical Lead role, you will play a key part in designing and building a large-scale, end-to-end model evaluation platform, while also shaping methodologies that drive improvements in model accuracy and performance. Your work will deliver high-quality offline evaluation insights that inform model development and elevate the user experience — all in alignment with Apple’s industry-leading standards for privacy and quality.

As part of the team advancing Apple Intelligence, you’ll take on challenges such as developing realistic simulation environments, and contributing to scalable evaluation pipelines that can evolve rapidly alongside shifting system architectures. With Siri becoming increasingly personal, you’ll collaborate closely across teams to implement evaluation solutions grounded in real-world, context-aware scenarios.

In this role, you will own requirements, including 'proof of concept' development, and co-own the development roadmap for ML system evaluation platform. You have a consistent record defining success by completing the full product cycle, from design and implementation to gathering feedback and iterating on systems, frameworks, and tools for Siri
