Job description

About the Role

We are looking for an experienced DevOps Engineer to join our infrastructure/platform team. You will design, build, and maintain scalable cloud infrastructure and CI/CD pipelines, with a strong focus on AWS and Red Hat OpenShift environments. This role has a strong DevSecOps component - you will be expected to embed security practices throughout the development and deployment lifecycle, not treat it as an afterthought.

Key Responsibilities

Infrastructure & Platform

• Design, implement, and maintain infrastructure-as-code (IaC) for AWS cloud environments
• Deploy, manage, and optimize containerized applications on Red Hat OpenShift (OKD/OCP)
• Manage Kubernetes/OpenShift clusters, including scaling, upgrades, and patching
• Troubleshoot and resolve infrastructure, networking, and deployment issues

CI/CD & Automation

• Build and maintain CI/CD pipelines to support development and release cycles
• Automate repetitive operational tasks to improve deployment speed and reliability
• Implement pipeline security gates (e.g., automated approval blocks on failed scans)

DevSecOps / Security Integration

• Embed security checks across the SDLC ("shift left") - including static application security testing (SAST), dynamic testing (DAST), and software composition analysis (SCA)
• Perform container/image vulnerability scanning before deployment to OpenShift (e.g., Trivy, Clair, Red Hat ACS/StackRox)
• Manage secrets securely using tools like HashiCorp Vault, AWS Secrets Manager, or OpenShift Secrets
• Implement policy-as-code and compliance-as-code (e.g., Open Policy Agent, OPA Gatekeeper) to enforce security and governance guardrails
• Apply IAM least-privilege principles across AWS and OpenShift RBAC configurations
• Monitor for security vulnerabilities, misconfigurations, and compliance drift in infrastructure and pipelines
• Support security audits, vulnerability remediation, and incident response processes
• Collaborate with security teams to align with organizational compliance frameworks

Monitoring & Reliability

• Implement and maintain monitoring, logging, and alerting solutions (e.g., Prometheus, Grafana, ELK/EFK)
• Support disaster recovery, backup strategies, and incident response procedures
• Document infrastructure architecture, security controls, runbooks, and operational procedures

Requirements

• Singapore Citizen , based in Singapore
• 3-5 years of relevant DevOps/DevSecOps/Platform Engineering experience
• Hands-on experience with AWS (EC2, S3, VPC, IAM, Lambda, RDS, CloudFormation/Terraform, etc.)
• Practical experience with Red Hat OpenShift (deployment, cluster management, operators, RBAC)
• Solid understanding of containerization technologies (Docker, Kubernetes)
