Senior Software Development Engineer in Test — LLM Evaluation & Automation, T3E

The Apple Intelligence Platform Experience Validation team builds the tooling and automation that keeps Apple Intelligence features high-quality before they ship. We are looking for a Senior SDET to lead the design and implementation of automated model evaluation: standing up LLM-as-a-judge in existing and new pipelines, and building the infrastructure that catches model regressions before they reach human evaluation or the live on population.

This is a hands-on, senior individual-contributor role. You will own eval automation as a discipline across the team, partnering with modeling, framework, and infrastructure teams to make model quality a first-class, continuously measured signal.
