Sr. Director, Back-End Engineering

Job Description – Sr. Director, TestOps

Coupang operates a large distributed technology ecosystem where changes must be validated quickly, safely, and repeatedly across infrastructure and application boundaries. We are seeking a Director, TestOps to build and lead testing as a platform capability. This leader will own test automation, test environments and data, integration testing, resilience validation, quality signals, and AI-assisted testing. The mission is to move testing from a manual phase owned independently by teams into an automated, federated, and measurable platform that enables safe continuous delivery. We are looking for a visionary quality-platform leader who has previously built and scaled comparable TestOps, test infrastructure, or continuous-quality systems in a leading global technology company.

Key Responsibilities

· Set a bold vision for testing as a company-wide platform capability and translate that vision into an executable roadmap adopted across infrastructure and domain organizations.

· Define and execute the TestOps strategy across Tech Infrastructure and partner engineering organizations.

· Build a federated testing platform that supports infrastructure, platform, API, UI, integration, resilience, and release validation.

· Create repeatable test capabilities for Unified Staging and production-like environments.

· Partner with Developer Platform, SRE, Observability, Security, and domain teams to embed quality gates into delivery workflows.

· Own testing metrics including coverage, pass rate, escaped defects, flaky tests, execution time, environment readiness, and release confidence.

· Drive adoption through product management, customer enablement, documentation, office hours, and clear service-level objectives.

Test Platform Automation

· Build self-service test planning, execution, orchestration, reporting, and evidence-management capabilities.

· Automate UI, API, service integration, infrastructure integration, and end-to-end test execution.

· Provide reusable test harnesses, reference applications, simulators, mocks, and service-virtualization capabilities.

· Integrate TestOps with CI/CD, Global CD, Application Registry, observability, and release governance.

· Create quality gates that are risk-aware, fast, deterministic, and appropriate to service tiers.

· Reduce flaky tests, duplicated frameworks, manual validation, and fragmented tooling.

Unified Staging, Test Data Resilience Validation

· Use Unified Staging as the default environment for validating Tech Infrastructure components and domain applications.

· Build compliant, desensitized, production-like test data generation and lifecycle management.

· Enable integration testing across identity, mesh, networking, databases, queues, storage, observability, and application dependencies.

· Partner with SRE to automate fault injection, DR scenarios, failover validation, load testing, and reliability certification.

· Ensure validation evidence can feed release decisions, RBD/RBO certification, and executive reliability metrics.

AI-Assisted Testing

· Build AI-assisted capabilities for feature test-plan generation, test-case generation, test-data generation, execution, failure analysis, and defect triage.

· Establish evaluation, safety, and quality mechanisms for AI-generated tests and recommendations.

· Use production telemetry and incident learnings to continuously improve test coverage and prioritize high-risk scenarios.

· Automate quality insights and next-best-action recommendations for engineers and release owners.

Talent Leadership Organization

· Lead managers, technical leads, and senior engineers across test platform, automation, and quality engineering.

· Own organization design, hiring, leadership development, and succession planning.

· Build a strong engineering culture focused on platform products rather than manual test execution.

· Develop leaders who can independently own federation, test infrastructure, AI TestOps, and resilience validation.

· Attract engineers with deep test infrastructure, distributed systems, developer tooling, and automation expertise.

Technical Leadership Architecture

· Own architecture for test orchestration, environment integration, test data, result storage, quality signals, and release gating.

· Define company standards for test APIs, frameworks, evidence, coverage, flakiness, and service-tier validation.

· Influence platform architecture to improve testability, observability, fault isolation, and safe deployment.

· Align test strategy with the broader observability and AIOps architecture so pre-release and post-release quality signals reinforce one another.

Execution Impact

· Deliver measurable reductions in manual testing, execution time, escaped defects, flaky tests, and release-related incidents.

· Increase automated integration and resilience validation across Tier 0, Tier 1, and Tech Infrastructure services.

· Improve release confidence and developer productivity through reliable self-
