• Assist in managing cloud infrastructure using IaC tools (Terraform, CloudFormation) to ensure consistent, version-controlled, and repeatable deployments.
• Support CI/CD pipeline improvements (GitLab CI, GitHub Actions, Jenkins) to enable safe and efficient application deployments.

Capacity Planning & Performance Tuning

• Collect and analyse resource usage trends (CPU, memory, storage, network) to help forecast capacity needs and recommend scaling actions.
• Work with development teams to conduct load testing and identify performance bottlenecks.

Collaboration & Knowledge Sharing

• Partner with software engineers to implement service level indicators (SLIs) and define realistic service level objectives (SLOs).
• Document system architecture, operational runbooks, and common troubleshooting steps to empower the wider team.
• Actively participate in team agile ceremonies, providing input on reliability risks for upcoming features.

Beneficial Skills (Desired Skills):

• Container Orchestration: Hands-on experience with Kubernetes (cluster administration, Helm charts, pod autoscaling) or Docker Swarm.
• Programming & Scripting: Proficiency in at least one high-level language (Python, Go) for automation and tooling; comfort with shell scripting.
• CI/CD Pipelines: Familiarity with building and maintaining deployment pipelines, including canary deployments, feature flags, and rollback strategies.
• Observability Stack: Experience with Prometheus, Grafana, Loki, Tempo, or the ELK Stack (Elasticsearch, Logstash, Kibana).
