Join a leading global e-commerce and digital services enterprise as a DevOps Engineer in Tokyo, working within an international engineering team responsible for supporting high-traffic, mission-critical infrastructure.
This contract opportunity focuses on DevOps engineering, Linux server administration, configuration management, CI/CD automation and container orchestration, offering hands-on experience with enterprise-scale systems supporting millions of users.
You will help maintain and optimise the infrastructure underpinning a large ecosystem of digital services, ensuring that production environments remain reliable, secure, scalable and operationally efficient.
A central responsibility will be developing and maintaining configuration management automation using Ansible and Chef, helping standardise server configurations, reduce manual intervention and maintain consistency across production environments.
You will also design, implement and improve continuous integration and continuous delivery (CI/CD) pipelines, supporting reliable application deployment and efficient software development workflows.
Working with Docker containers and Kubernetes clusters, you will help build, deploy and orchestrate containerised applications across complex infrastructure environments.
The role also involves managing Linux/Unix production servers, proxy configurations and infrastructure availability, contributing to stable operations and effective security controls.
You will monitor system health, investigate operational issues and collaborate with engineers across different technical disciplines to troubleshoot incidents, minimise downtime and improve infrastructure performance.
As part of a multicultural engineering organisation, you will communicate primarily in English, working with colleagues from diverse professional and cultural backgrounds. Japanese-language proficiency is not required.
This opportunity is particularly well suited to engineers with experience in DevOps, Site Reliability Engineering (SRE), infrastructure automation, Linux systems administration, Kubernetes or CI/CD engineering who want to strengthen their expertise in large-scale production environments.
