• Write and maintain automation scripts using PowerShell, Bash, or Python.
• Support the monitoring of SLIs, SLOs, and SLAs to help ensure system reliability.
• Assist in configuring and maintaining monitoring, logging, and alerting solutions (CloudWatch, Prometheus, Grafana, Azure Monitor).
• Participate in incident response and troubleshooting under the guidance of senior engineers, contributing to root cause analysis (RCA).
• Support performance monitoring and capacity planning activities.
• Work with development teams to understand and support deployment strategies (blue-green, canary releases).
• Follow security, compliance, and best practices across CI/CD pipelines and infrastructure.

 

Required Skills & Experience

• Up to 2 year of experience or relevant internship/placement in Site Reliability Engineering, DevOps, or Infrastructure Engineering (graduate applicants with strong academic projects welcome).
• Basic understanding of AWS services (EC2, S3, RDS, VPC, IAM, ELB, CloudWatch).
• Familiarity with CI/CD concepts and exposure to Azure DevOps Pipelines or similar tools.
• Basic understanding of pipeline design and deployment strategies.
• Foundational knowledge of Windows Server administration, including IIS and .NET applications.
• Basic Linux system administration skills.
• Awareness of containerisation concepts (Docker) and an interest in Kubernetes (EKS/AKS).
• Exposure to Infrastructure as Code concepts (Terraform, CloudFormation, or ARM templates).
• Basic scripting ability in at least one of PowerShell, Bash, or Python.
• Familiarity with monitoring and logging concepts and tools (Prometheus, Grafana, ELK, CloudWatch).
• Foundational understanding of networking, security, and cloud architecture principles.

Preferred Qualifications

• A degree in Computer Science, Software Engineering, or a related discipline (or equivalent practical experience).
• Any hands-on experience with cloud platforms (AWS, Azure, or GCP) through personal projects, labs, or coursework.
• Familiarity with version control systems (Git).
• Exposure to Helm, GitOps practices, or service mesh concepts.
• Interest in obtaining relevant certifications (AWS, Kubernetes, Azure DevOps).

Key Competencies / Characteristics

• Eager learner: Proactively seeks to build knowledge in SRE practices, cloud-native technologies, and automation.
