• Implement authentication and authorisation controls, including integration with government identity frameworks and standards such as OIDC and SAML
• Build and maintain CI/CD pipelines , deploy containerised workloads to Kubernetes, and instrument applications for observability and monitoring
• Support production deployments, participate in incident resolution, and contribute to ongoing operational stability
• Write clean, well-tested, and documented code; participate actively in code reviews and engineering best-practice discussions

Additional responsibilities for Senior Consultant level

• Define technical architecture and target-state design for the modernised platform, including migration sequencing, risk management, and cutover planning
• Lead delivery across multiple workstreams, coordinating with product owners, DevSecOps teams, and agency stakeholders
• Set engineering standards, provide strategic technical direction, and mentor team members

Requirements

• Consultant level: Minimum 3-5 years of hands-on full stack development experience; Senior Consultant level: 7 or more years, including at least 2-3 years leading technical delivery or defining solution architecture
• Proficiency in frontend development with ReactJS and TypeScript, and backend development with Golang and/or Kotlin
• Hands-on experience with DevOps practices including CI/CD pipelines, Docker, and Kubernetes , as well as AWS cloud services and Terraform (or equivalent IaC tooling)
• Demonstrated experience migrating or modernising legacy applications is strongly preferred; prior delivery on Singapore Government or public sector projects (is a bonus)
• Familiarity with observability platforms (e.g. Dynatrace, Datadog), workflow engines (e.g. Temporal), or rules engines (e.g. Open Policy Agent) (is a bonus)
