Senior Full Stack Engineer

Our California-based customer is a leading American global e-commerce company, one of the most popular and successful websites on the Internet. It provides platform services by connecting millions of sellers and buyers across more than 190 markets worldwide.

The Engineering Systems Tools team builds and operates the internal tooling and infrastructure that supports thousands of developers across the company. Our mission is to enhance developer efficiency through automation, self-service platforms, and seamless provisioning. We support and extend core platforms, including JIRA, Confluence, GitHub Enterprise, Artifactory, SonarQube, Gradle, and Airtable, while building and maintaining custom applications tailored to internal engineering workflows.

On the infrastructure side, we operate across multi-cloud environments (GCP, AWS, Azure), and are actively investing in container orchestration (Kubernetes), infrastructure-as-code, and service automation to modernize our stack.

We own the full lifecycle of our tools - from development and deployment to monitoring and operations - and collaborate closely with teams across the company to deliver resilient, scalable solutions.
