DevOps Engineer/Platform Engineer

About the Role

In this hands-on infrastructure and automation role, you will design, provision, maintain and improve secure, scalable, and resilient AWS cloud infrastructure, CI/CD pipelines, and observability systems. You will work closely with software engineers, quality engineers, operations support and product managers to ensure reliability, security compliance, and engineering excellence across the platform.

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).

● Exposure to AWS Lattice and Jaeger for microservices distributed tracing.

● Familiarity with rule engines (e.g., IBM ODM) and backend frameworks (Kotlin, Spring Boot. Camel).

● Familiarity with SRE concepts, DORA metrics, and performance testing frameworks (Locust)
