Evaluation Reliability SRE

Join the team redefining what a deeply personal and integrated assistant can be. nnAs part of the Siri organization you will help shape one of the worlds most widely used AI assistants powered by our next-generation of Apple Intelligence with capabilities like personal context understanding and on-screen awareness built with privacy from the ground up. Your work will have direct meaningful impact for users across iOS iPadOS macOS watchOS and is a rare opportunity to build at the intersection of cutting-edge AI and human-centered design shipping technology that is centered around users and their needs.n

Siris quality signal drives every model and product decision before a release ships. But a signal is only as trustworthy as the infrastructure behind Evaluation Reliability Engineering (ERE) team exists to make that infrastructure bulletproof. Within ERE Core SRE owns the production backbone: resource management session orchestration on-call response and the observability systems that surface failures before they corrupt evaluation signal. We sit at the intersection of distributed systems ML evaluation infrastructure and operational is a senior hands-on role. You share primary on-call as part of a global follow-the-sun rotation lead incident investigations end-to-end and set the operational bar the rest of the team works against. You are fluent with agentic coding tools like Claude Code Cursor or Copilot and use them as a force multiplier across runbook authoring automation and log analysis.n
