Job description

Core Responsibilities:

Canary setup for app observability under AWS CloudWatch

• a. Design, configure and maintain AWS CloudWatch Synthetics Canaries and related monitoring capabilities for applications, in accordance with application observability and monitoring requirements.
• b. Write and refine canary test scripts per application to accurately validate functionality/availability; iterate on scripts in UAT before promoting to PRD, and refine again in PRD to account for environment-specific differences (network paths, auth, endpoint configurations).
• c. Implement application health checks, availability monitoring, performance monitoring, dashboards, metrics, logs and alerts to provide proactive visibility of application health.
• d. Enable CloudWatch dashboard/metrics visibility in the observability PRD account so canary results are viewable by stakeholders.
• e. Troubleshoot and resolve any canary failures or false positives during rollout.
• f. Work with application teams to troubleshoot performance and availability issues identified through monitoring and observability tools.
• g. Support continuous improvement of application monitoring, alerting and operational dashboards.

Perform the migration to support application deployment

• a. Plan and execute the migration of the existing CI/CD runner to the GovTech-managed runner for applications.
• b. Assess existing build and deployment configurations, dependencies, environment variables, credentials and integration requirements prior to migration.
• c. Perform configuration, testing, troubleshooting and validation to ensure applications can be successfully built and deployed through the GovTech-managed environment.
• d. Work with GovTech and application teams to resolve deployment pipeline and runner-related issues.

Support backend work, e.g. setup of MCP Servers for AI integration

• a. Design, develop, configure and maintain backend integration components and services required by applications.
• b. Set up and maintain Model Context Protocol (MCP) servers and associated APIs/services to enable AI-enabled applications to securely access authorised knowledge sources.
• c. Develop integrations with systems and knowledge repositories.
• d. Implement appropriate authentication, authorisation, API management, logging, error handling and data transformation mechanisms for system-to-system integrations.
• e. Work with application and data owners to understand source-system interfaces and develop reusable integration services where appropriate.

Support and manage SHIP-HATS application deployment pipelines for new and existing products/applications, including migration of existing products/applications to Infrastructure-as-Code (IaC) setup

• a. Work closely with product and application teams to establish, configure and manage SHIP-HATS CI/CD deployment pipelinesb. Support the onboarding and migration of existing applications onto SHIP-HATS deployment processes.
• b. Review existing application deployment architecture and progressively migrate manually configured infrastructure and deployment components towards Infrastructure-as-Code (IaC).
• c. Develop and maintain IaC templates/scripts for consistent and repeatable provisioning and deployment across development, testing and production environments.
• d. Troubleshoot CI/CD pipeline, deployment, environment and infrastructure configuration issues.
• e. Promote reusable deployment patterns and automation to reduce manual deployment effort and configuration inconsistencies.
