The Job at a Glance
As a Principal Backend Engineer, you will design, architect, and optimize scalable microservices that power our eCommerce and enterprise platforms. You'll drive backend architecture and ensure seamless integration across systems like commerce, CMS, ERP, PIM, and marketing. Championing best practices in modularization, API design, and event‑driven architectures, you'll leverage Node.js, TypeScript, Docker, Kubernetes, and serverless technologies to create secure, high‑performance services.

You’ll own backend engineering policies, CI/CD pipelines, and testing automation to ensure reliable deployments. As a technical leader, you'll define logging, observability, and disaster recovery strategies, ensuring high availability. Collaboration with frontend, DevOps, and data teams will be key to optimizing system performance. Mentoring engineers and contributing to architectural decisions will be central to your role. This position is ideal for someone with extensive experience in backend design and distributed systems.
