Role Overview
We are looking for DevSecOps Engineers to design, build, and operate secure, cloud-native, containerised infrastructure on AWS for a Singapore public sector modernisation project. The role combines infrastructure engineering, cloud security, and secure software delivery, embedding security across infrastructure and the development lifecycle.
Key Responsibilities
- Set up modern cloud-native, containerised infrastructure on AWS using Infrastructure as Code (e.g. Terraform), covering VPC networking, EKS/ECS, RDS, and container registry across dev, staging, and production environments.
- Apply cloud security practices and controls, including least-privilege IAM, EKS Pod Identity, network isolation, system and container hardening, mTLS, secrets management, and encryption at rest and in transit.
- Build security into the development process by integrating SAST, dependency, secret, container image, and IaC scanning into GitLab CI/CD pipelines, with defined pass/fail gates.
- Set up and maintain monitoring, alerting, and observability using tools such as Dynatrace or Datadog.
- Support production deployments and incident resolution, including writing and maintaining runbooks.
- Design, implement, and regularly test backup and restore procedures.
- Integrate infrastructure with identity and access controls (e.g. ADFS, WOG AD, SAML, OIDC, CAM).
Additional responsibilities for Senior Consultant
- Define the secured infrastructure architecture and security baseline for the platform.
- Set up and govern secure infrastructure standards, guardrails, and practices across the team.
- Provide guidance and mentoring to engineers on secure infrastructure and DevSecOps practices.
- Work with agency security teams on security reviews, compliance requirements, and remediation of findings.
