Autonomous Operations</h3> <ul> <li>Transform incident management into a fast, disciplined, data-driven, and increasingly autonomous operating model.</li> <li>Enable AI-assisted detection, event correlation, triage, escalation, root-cause drafting, remediation recommendations, and selected guardrailed auto-remediation.</li> <li>Improve incident command, on-call quality, escalation mechanisms, communication, post-incident learning, and corrective-action completion.</li> <li>Reduce noisy alerts, manual on-call work, repeated diagnosis, and time spent coordinating across fragmented systems.</li> <li>Use incident and telemetry data to continuously improve platform standards, testing, capacity models, and engineering roadmaps.</li> </ul> <h3>Disaster Recovery, Resilience &amp; Capacity</h3> <ul> <li>Own the strategy and execution model for disaster recovery, regional resilience, availability-zone loss, capacity-constrained recovery, and critical business continuity.</li> <li>Build reusable DR and failover mechanisms that services inherit from the platform rather than implement as bespoke projects.</li> <li>Establish objective RPO/RTO targets, automated readiness gates, regular game days, fault injection, and evidence-based recovery certification.</li> <li>Drive proactive and intelligent capacity management using forecasting, reservations, workload prioritization, and automated response to demand and failure scenarios.</li> <li>Partner with compute, traffic, networking, storage, and application leaders to enable safe zone evacuation, regional failover, and surge readiness.</li> </ul> <h3>Observability, Testing &amp; Reliability Intelligence</h3> <ul> <li>Partner with Observability and TestOps leaders to integrate logs, metrics, traces, continuous profiling, testing, and incident intelligence into one reliability feedback loop.</li> <li>Ensure every critical service has actionable telemetry, meaningful SLOs, release-quality signals, and production-readiness evidence.</li> <li>Use production incidents and operational patterns to drive targeted integration, load, resilience, and regression testing.</li> <li>Establish executive reliability dashboards that provide trusted views of service health, risk, capacity, and operational effectiveness.</li> </ul> <h3>Talent Leadership &amp; Organization</h3> <ul> <li>Lead multiple layers of SRE leaders, including senior managers, directors, principal engineers, and senior individual contributors.</li> <li>Own organizational design, global hiring strategy, leadership development, succession planning, and the creation of a strong leadership bench.</li> <li>Attract exceptional SRE, distributed systems, resilience, incident-management, and capacity-engineering talent from best-in-class technology organizations.</li> <li>Build an empowered organization with clear accountability, strong technical judgment, high execution velocity, and a company-wide perspective.</li> <li>Act as a force multiplier by mentoring technical and organizational leaders and raising reliability capabilities across engineering.</li> </ul> <h3>Technical Leadership &amp; Architecture</h3> <ul> <li>Own reliability architecture decisions across large-scale distributed systems and cloud-native infrastructure.</li> <li>Define resilient patterns for redundancy, failover, traffic management, data recovery, workload prioritization, and dependency isolation.</li> <li>Guide architecture reviews and platform standards for safe scaling, fault tolerance, and operational simplicity.</li> <li>Balance availability, customer impact, engineering velocity, cost, and operational complexity in major technical decisions.</li> <li>Maintain sufficient technical depth to challenge assumptions, guide principal engineers, and make high-quality decisions during critical incidents.</li> </ul> <h3>Execution &amp; Impact</h3> <ul> <li>Deliver measurable improvements in availability, time to detect, time to mitigate, time to recover, incident recurrence, change-failure rate, and on-call burden.</li> <li>Create disciplined operating rhythms, milestones, ownership models, and quarterly targets for strategic reliability programs.</li> <li>Increase adoption of common reliability mechanisms and reduce team-specific implementations and manual operations.</li> <li>Demonstrate business impact through improved customer experience, reduced outage exposure, stronger peak readiness, and more efficient use of infrastructure capacity.</li> <li>Build credibility through predictable delivery, transparent risk management, and objective evidence of reliability improvement.</li> </ul> <h3>Essential Qualifications</h3> <ul> <li>Leadership experience in a best-in-class SRE, production engineering, infrastructure reliability, or cloud operations organization at hyperscaler, major cloud provider, global marketplace, leading fintech, or similarly scaled technology company.</li> <li>Experience building an SRE practice comparable in maturity to leading industry organizations, rather than operating a traditional support or operations function renamed as SRE.</li> <li>Experience with Kubernetes, service mesh, cloud-native platforms, traffic engineering, and large-scale capacity management.</li> <li>Experience with chaos engineering, fault injection, regional resilience, and automated disaster recovery.</li> <li>Experience building AI-assisted operations, incident intelligence, predictive reliability, or self-healing systems.</li> <li>15+ years of experience in software engineering, infrastructure engineering, distributed systems, or site reliability engineering.</li> <li>8+ years leading large-scale, multi-layer engineering organizations, including senior managers, directors, and senior individual contributors.</li> <li>Demonstrated experience personally defining the vision and leading the architecture, build-out, launch, and scaled adoption of a company-wide SRE, reliability, resilience, or autonomous-operations program.</li> <li>Prior experience building reliability systems and operating practices for high-scale, high-availability, customer-critical distributed systems.</li> <li>Deep expertise in SLOs, error budgets, observability, incident management, disaster recovery, capacity planning, and resilience engineering.</li> <li>Proven ability to lead through major incidents while also creating durable mechanisms that prevent recurrence.</li> <li>Recognized as a visionary technology and organizational leader who can influence executive stakeholders, align multiple engineering organizations, and attract exceptional talent.</li> <li>Proven ability to convert long-term strategy into measurable execution and company-wide adoption.</li> </ul>
