About the job
Join Coupang as a Senior Tech Infrastructure Engineer within our Developer Platform team, where you will collaborate closely with leaders across multiple platform teams. Your mission will be to define and implement streamlined solutions to intricate orchestration challenges, creating a highly scalable, reliable, and efficient platform for our customers. You will develop and engineer Kubernetes controllers, operators, and node-level daemons for application runtime; conduct performance tuning and scaling; and design multi-cluster control-plane capabilities capable of scaling to millions of pods across thousands of clusters.
Key Responsibilities:
- Develop a unified application platform for hybrid (multi-cluster, multi-region, multi-cloud) application management using Kubernetes controllers and feedback-driven control systems to meet service level objectives (SLOs).
- Automate the application lifecycle (deployments, rollouts, failovers, policy enforcement) to reduce manual intervention for users.
- Optimize fleet-wide performance, cost, and latency using data-informed controls and capacity management, enhancing $/RPS and tail latency.
- Create resilient, multi-tenant control planes and workflows that efficiently scale to millions of pods across thousands of clusters.
- Ensure reliability, security, and governance with defined guardrails, safe defaults, and automated remediation processes.
- Collaborate with product teams and customers to transform complex orchestration challenges into simple, reusable platform components and exceptional developer experiences.
- Promote observability and continuous improvement through measurable, outcome-focused metrics.
