Evaluation Reliability SRE

Join the team redefining what a deeply personal and integrated assistant can be.

As part of the Siri organization, you will help shape one of the world's 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 visionOS.

This 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.

Description

Siri's quality signal drives every model and product decision before a release ships. But a signal is only as trustworthy as the infrastructure behind it.

The 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 excellence.

This 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.

Responsibilities:

Own reliability outcomes across the evaluation infrastructure stack: orchestration, capacity, and service health

Own runbook quality across the team: author runbooks for complex failure categories and set the bar that guides other engineers to produce the same quality

Build deep expertise in the device orchestration and provisioning layers - understand quota management, retry behavior, and failure modes well enough to diagnose upstream issues independently

Instrument infrastructure components that lack observability; if a failure is hard to detect, make it easy to detect before the next occurrence

Balance incident response with proactive reliability work - automation and eliminating recurring failures are core deliverables

Partner on SLO definition and burn-rate alerting; bring the operational depth that turns reliability targets from aspirational to measurable

Influence the team's technical roadmap, mentor junior SREs, and represent infrastructure reliability posture to leadership and in cross-team reviews

Preferred Qualifications

Experience owning or closely operating a device or VM provisioning pipeline; familiarity with virtualization-layer failure modes is a strong plus

Track record of improving system reliability against measurable outcomes - uptime, MTTR, incident frequency - not just responding to incidents but eliminating their causes

Incident command discipline: able to lead a multi-team incident from declaration to close-out

Depth in at least one of: distributed systems reliability, device management infrastructure, evaluation or ML platform operations

Demonstrated cross-team technical influence; prior experience shaping reliability practices beyond the immediate team

Minimum Qualifications

5+ years of site reliability, infrastructure, or platform engineering experience with direct on-call ownership in production systems

Hands-on orchestration experience (Kubernetes or equivalent): cluster health, resource management, scheduling, and failure diagnosis at scale
