Sr. Director, Back-End Engineering

Role details

Sr. Director, Developer Platform We exist to wow our customers. We know we’re doing the right thing when we hear our customers say, “How did we ever live without Coupang?” Born out of an obsession to make shopping, eating, and living easier than ever, we’re collectively disrupting the multi-billion-dollar e-commerce industry from the ground up. We are one of the fastest-growing e-commerce companies that established an unparalleled reputation for being a dominant and reliable force in South Korean commerce. We are proud to have the best of both worlds — a startup culture with the resources of a large global public company. This fuels us to continue our growth and launch new services at the speed we have been since our inception. We are all entrepreneurial surrounded by opportunities to drive new initiatives and innovations. At our core, we are bold and ambitious people that like to get our hands dirty and make a hands-on impact. At Coupang, you will see yourself, your colleagues, your team, and the company grow every day. Our mission to build the future of commerce is real. We push the boundaries of what’s possible to solve problems and break traditional tradeoffs. Join Coupang now to create an epic experience in this always-on, high-tech, and hyper-connected world. About the Role Coupang operates one of the largest and most complex technology platforms in the world. We are seeking a Senior Director, Software Supply Chain Platform to build and lead the company-wide platform for secure, reproducible, and automated software delivery. This leader will own build systems, dependency and library management, artifact repositories, software provenance, supply chain security, and automated remediation. The mission is to ensure every Coupang service is built from approved, patched, traceable, and policy-compliant components while removing dependency-management and patching burden from domain engineering teams. We are looking for a visionary, industry-recognized platform leader who has previously conceived, built, and scaled comparable build, dependency, or software supply chain systems in a leading global technology company. What You Will Do Set a bold, multi-year vision for software supply chain and build platforms, translate that vision into an executable roadmap, and align senior leaders across engineering and security. Define and own the company-wide strategy for secure builds, dependency governance, artifact management, and software supply chain automation. Build a unified platform that manages internal and third-party libraries, coordinated version sets, frameworks, base images, and build artifacts. Establish developer golden paths that make secure and compliant software delivery the default experience. Create strong partnerships across Developer Platform, Security, Infrastructure Automation, and application engineering organizations. Drive adoption of centralized build and dependency services and retire fragmented or unsupported workflows. Own product metrics including adoption, build reliability, upgrade velocity, vulnerability remediation time, developer productivity, and platform cost. Build, Dependency & Artifact Platform Design and operate large-scale build and dependency-management capabilities inspired by systems such as Amazon Brazil, Bazel, Buck, or equivalent enterprise platforms. Enable hermetic, reproducible, and policy-controlled builds across a large polyglot codebase. Create coordinated version-set and dependency-graph capabilities that prevent uncontrolled library drift and incompatible upgrades. Own enterprise artifact repository strategy, package intake, curation, retention, promotion, and distribution. Provide approved golden libraries, frameworks, build templates, container base images, and runtime packages. Automate library and framework upgrades through safe, testable, and scalable pull-request generation. Software Supply Chain Security & Automation Establish end-to-end artifact provenance, SBOM generation, signing, attestation, and verification. Integrate vulnerability detection, application risk context, policy enforcement, and remediation into build and release workflows. Prevent unapproved or vulnerable dependencies from entering production through automated policy gates and exception governance. Coordinate automated remediation for third-party packages, container base images, AMIs, frameworks, and runtime dependencies. Build controls for trusted sources, package integrity, malicious package detection, and software for end-of-life management. Partner with App Registry and security systems to prioritize remediation based on service tier, criticality, ownership, and customer risk. Talent Leadership & Organization Build and lead multiple teams spanning build systems, dependency platforms, artifact security, and automated remediation. Own organizational design, hiring strategy, leadership development, and succession planning. Attract senior engineers with deep build-system, compiler/toolchain, package-management, and software supply chain expertise. Develop senior managers and principal engineers who can independently own major platform capabilities. Create a customer-focused culture that treats domain engineering teams as platform customers rather than ticket sources. Technical Leadership & Architecture Own architecture for build orchestration, dependency resolution, artifact trust, provenance, and policy enforcement at Coupang scale. Define integration patterns with CI/CD, Deployment Tool, Application Registry, vulnerability management, and runtime platforms. Influence company-wide engineering standards for builds, libraries, frameworks, containers, and release artifacts. Balance security, developer velocity, reliability, and cost while simplifying the technology landscape. Execution & Impact Deliver measurable reductions in vulnerable dependencies, manual patching effort, build failures, and upgrade lead time. Increase adoption of trusted libraries, signed artifacts,
