• Remove deployment dependencies between services and improve build efficiency
• Support testing in isolated environments
• Introduce blue/green or canary releases where they make sense
• Build reliable rollback mechanisms for all services

Observability and Incident Response

• Set up one system for monitoring, logging and tracing
• Put alerting in place that matches what engineering needs
• Introduce standard dashboards and improve incident response workflows

Reliability and Resilience

• Make sure backup, restore and disaster recovery procedures work
• Improve auditability, reproducibility and visibility in deployment operations
• Refine runbooks and operational processes
• Review and improve infrastructure redundancy, replication and fault tolerance
• Apply clear reliability practices that support scaling

Infrastructure as Code and Cloud Governance

• Continue assessing current IaC usage
• Move manual infrastructure into code to reduce drift
• Improve governance and resource organisation across cloud accounts

Security

• Build secure container pipelines with vulnerability scanning
• Strengthen IAM practices, certificate management and secrets handling
• Apply foundational security baselines and best practices
• Set up centralised configuration and secrets management

Developer Experience

• Reduce reliance on local scripts and manual .env coordination
• Build tools and workflows that make development and testing simpler

Requirements

• Experience in DevOps, Site Reliability Engineering or Platform Engineering
• Strong AWS expertise across compute, networking, IAM and monitoring services
• Proficiency with Docker and modern container workflows
• Deep familiarity with IaC tools such as CDK or Terraform
• Experience building or integrating observability systems
• Comfortable automating infrastructure and operational processes
• Strong scripting in Bash, Python or Node.js

Nice to Have

• Hands-on CI/CD experience, ideally with GitHub Actions
