<p><strong>Sr. Director, Site Reliability Engineering</strong></p> <p>Coupang operates one of the largest and most complex technology platforms in the world. We are seeking a Senior Director, Site Reliability Engineering (Head of SRE) to define and lead company-wide reliability, resilience, scalability, and operational excellence. This leader will transform reliability from a collection of team-specific practices into platform mechanisms that services inherit by tier, while advancing incident response toward an intelligent, AI-assisted, and increasingly autonomous operating model. We are looking for a visionary, industry-recognized technology leader who has previously conceived, built, and scaled a comparable SRE, production engineering, resilience, or autonomous-operations organization at a leading global technology company. The successful candidate must combine deep technical credibility with the organizational leadership required to align executives, influence architecture across the company, and build a world-class leadership bench.</p> <h3>Key Responsibilities</h3> <ul> <li>Set a bold, multi-year vision for company-wide reliability, resilience, and autonomous operations, and translate that vision into an executable roadmap with measurable business outcomes.</li> <li>Define and own the SRE strategy, operating model, engineering standards, and reliability governance across Coupang.</li> <li>Build platform mechanisms that allow services to inherit reliability requirements based on service tier rather than recreate them independently.</li> <li>Lead initiatives that materially improve availability, resilience, scalability, performance, and operational readiness.</li> <li>Partner with engineering, product, infrastructure, security, finance, and business leaders to align reliability investments with customer and business priorities.</li> <li>Own executive reliability metrics, including availability, detection and recovery performance, change risk, incident recurrence, capacity readiness, and operational toil.</li> <li>Build and scale a world-class SRE organization capable of influencing engineering practices across the company.</li> </ul> <h3>Reliability Strategy, SLOs & Engineering Governance</h3> <ul> <li>Establish and evolve service-tier definitions, SLOs, SLAs, error budgets, reliability scorecards, and objective certification mechanisms such as RBD/RBO.</li> <li>Create clear reliability requirements for Tier 0, Tier 1, and Tier 2 services, including redundancy, load testing, disaster recovery, observability, and incident response.</li> <li>Ensure reliability governance is embedded in architecture, development, release, and production operations rather than applied as a final review.</li> <li>Drive systematic reduction of recurring incidents, reliability risks, operational debt, and unsafe change patterns.</li> <li>Influence company-wide architecture for graceful degradation, fault isolation, load shedding, circuit breaking, and failure containment.</li> </ul> <h3>Incident Management & 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 & 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 & 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 & Organization</h3> <ul> <li>Lead multiple layers of SRE leaders, including senior managers, directors, principal engineers, and senior individual c
