Senior DevOps Engineer

Responsibilities

• Design, develop, and maintain CI/CD pipelines using GitLab CI/CD to support a robust and efficient software delivery lifecycle.
• Manage and maintain infrastructure on cloud platforms (especially GCP) using Infrastructure as Code (IaC) practices with tools such as Terraform.
• Deploy and operate applications on Kubernetes (GKE), including configuration for autoscaling, security, and cost optimization.
• Utilize tools such as ArgoCD to implement GitOps and automate deployments across multiple environments.
• Build and manage monitoring and alerting systems using Prometheus, Grafana, Cloud Monitoring (Stackdriver), and other observability tools.
• Collaborate with Development, QA, and Security teams to ensure systems are performant, secure, and auditable.
• Manage and maintain database systems such as PostgreSQL, MySQL, and MongoDB with a focus on performance, availability, and backup strategies.
• Investigate and resolve production issues related to system performance, reliability, and scalability.
• Contribute to the design of Disaster Recovery and High Availability strategies.
• Advocate and lead the adoption of DevOps best practices within the team and provide technical mentorship to peers.

Qualifications

• Minimum 3 years of experience in DevOps, SRE, or Infrastructure Engineering.
• Strong expertise in cloud platforms (e.g., GCP, Huawei Cloud), including services such as networking (VPC), databases (Cloud SQL), load balancing, and IAM.
• Proficient in containerization and orchestration, including Docker and Kubernetes (both workload and cluster operations), with experience in tools within the Kubernetes ecosystem such as Helm and Kustomize.
• Experience in Infrastructure as Code (IaC) using tools like Terraform or Pulumi.
• Hands-on experience with CI/CD pipelines (e.g., GitLab CI/CD) and GitOps practices (e.g., Argo CD).
• Experience with observability and monitoring tools such as Prometheus, Grafana, and cloud-native monitoring solutions (e.g., Google Cloud Monitoring).
• Solid understanding of system security, including IAM, secret management (e.g., HashiCorp Vault), network policies, authentication/authorization (OAuth2, OIDC), and access control (RBAC/ACL), as well as integration with Identity Providers (IdP).
• Strong Linux administration skills, including shell scripting (bash/sh) for automation and troubleshooting.
• Experience designing and managing service mesh architectures (e.g., Istio), including traffic management, mTLS, and policy enforcement.
• Experience managing both relational and NoSQL databases (e.g., PostgreSQL, MySQL, MongoDB).
• Proven experience operating large-scale, highly available, and scalable systems, particularly in microservices architectures.
• Strong communication skills and ability to collaborate effectively with cross-functional teams (Dev, QA, Product, Security).
