Responsibilities

• Design, build and maintain infrastructure on Azure and AWS (and occasionally GCP) using infrastructure‑as‑code.
• Standardise and optimise Docker images for our Python and TypeScript services.
• Manage container runtimes and orchestration platforms (e.g. Docker Compose, Kubernetes, ECS, AKS, etc.).
• Implement image scanning, registry management and deployment strategies (blue/green, canary, rolling).
• Design and maintain CI/CD pipelines to build, test and deploy applications across environments.
• Integrate automated testing, security checks and quality gates into the pipelines.
• Automate repetitive operational tasks using scripts and tooling (Python, Bash, etc.).
• Collaborate with developers to define branching strategies, release processes and rollback procedures.
• Implement and maintain monitoring, logging and alerting for applications and infrastructure.
• Participate in incident response, root‑cause analysis and post‑incident reviews.
• Work with security and engineering teams to implement best practices for secrets management, access control and hardening of Linux, cloud resources and container images.

KEY REQUIREMENTS:

• Strong hands‑on experience with Linux (preferably in a server or VM context).
• Strong practical experience with Docker (creating, optimising and running containers in production).
