Key Responsibilities
Technical Delivery & Ownership
● Design, provision, and maintain secure, scalable, and resilient AWS cloud infrastructure using Terraform/Terragrunt and EKS (Fargate).
● Implement GitOps continuous deployment workflows, blue/green and canary deployment strategies with Argo CD and Helm.
● Build and maintain GitLab CI/CD pipelines integrating automated static code analysis and dependency/vulnerability scanning (OWASP, Gitlab SAST, Trivy, AWS Inspector).
● Collaborate with SWE Tech Leads to support backend APIs, microservices, and rule engine integrations.
Domain & System Expertise
● Develop strong knowledge of claim processing workflows and CPF balance/limit querying APIs.
● Automate operational workflows and establish single-source-of-truth technical documentation.
● Enforce security patching, secure configurations, and resolve findings from AWS Security Hub, GCSOC, and government compliance policies (GCC 2.0, SHIP-HATS 2.0).
Incident & Reliability
● Set up, manage, and expose monitoring dashboards and alerting for proactive issue resolution
○ Prometheus, Grafana, OTel, Jaeger, CloudWatch
● Diagnose and resolve complex container/pod operational issues
● Participate in ROTA operational support, incident response, and blameless postmortems.
Team Contribution & Collaboration
● Collaborate with cross-functional teams (SWE, QE, PMs, Ops Support) to plan and prioritize infrastructure tasks in an Agile setup.
● Share technical ideas, success stories, and learnings in an open, continuous improvement culture.
● Promote DevOps best practices, security awareness, and developer self-diagnosis capabilities across the engineering team.

● Hands-on proficiency with AWS Cloud services and Kubernetes (EKS Fargate).
● Proven expertise in Infrastructure as Code (Terraform, Terragrunt) and containerization (Docker).
● Proficient in scripting (Shell/Bash, Python) for operational automation.
● Experience building and maintaining CI/CD pipelines (GitLab CI/CD) with security scans.
● Practical knowledge of GitOps tools (Argo CD, Helm) and deployment strategies (Canary, Blue/Green).
● Solid experience with monitoring and observability tools (Prometheus, Grafana, AWS CloudWatch, OpenTelemetry).
● Strong troubleshooting skills for microservices (analyzing container logs, events, resource requests/limits).
● Strong team player and proactive communicator who speaks up for engineering best practices and quality.
Nice-to-Have
● Experience with Singapore Government cloud standards and tools (GCC 2.0, SHIP-HATS 2.0).
