You’ll collaborate closely with backend, frontend, and data teams in both Vietnam and Europe to align on CI/CD, observability, and infrastructure resilience.

What you’ll lead & do

• Architect, build, and maintain CI/CD pipelines using GitHub Actions, GitLab CI, or Jenkins.
• Manage containerized environments via Docker and Portainer; lead the migration toward Kubernetes/OpenShift clusters.
• Implement and manage Traefik for intelligent routing, load balancing, and SSL termination.
• Automate infrastructure deployment through Infrastructure as Code (Terraform, Ansible, etc.).
• Set up and maintain observability stacks (Prometheus, Grafana, ELK) for proactive monitoring and incident prevention.
• Enforce security best practices, including vulnerability scanning, system hardening, and secure container deployment.
• Optimize networking layers for performance, reliability, and scalability.
• Collaborate with developers to accelerate build-test-deploy cycles through efficient DevOps workflows.
• Document all architecture, configuration, and recovery procedures for long-term maintainability.

Key projects & administrative duties

• CI/CD Evolution: Lead the modernization of our build pipelines and automated deployments across multiple services.
• Container Orchestration Migration: Plan and execute the transition from legacy environments to Kubernetes or OpenShift.
• Observability 2.0: Design a unified monitoring and alerting ecosystem integrating Grafana, Prometheus, and centralized logging.
• Infrastructure Security: Implement a standardized security baseline for Linux servers, containers, and internal services.
• DevOps Knowledge Base: Create internal documentation, runbooks, and infrastructure diagrams for long-term scalability

• Competitive salary Full health & social insurance (retirement, sick leave, maternity) 
• Paid annual leave + guaranteed Tet bonus Gym membership, sports activities, team events
