Job summary

LDMS is seeking a Junior Infrastructure Engineer in Cardiff to help build and support the cloud infra behind our SaaS products and internal tooling. You will learn AWS services (EC2, VPC, ECS, RDS, IAM), IaC (Terraform) and CI/CD practices while contributing to security, monitoring, and automation.

You will work alongside experienced engineers, gaining hands-on experience with Oracle RDBMS, Intune, and modern deployment pipelines. A degree or 1–2 years’ related experience is expected.

Qualifications

• 1–2 years’ experience in an infrastructure, cloud, or IT operations role, or a relevant degree plus around a year of industry experience (e.g. placement year or internship). Certifications such as AWS Cloud Practitioner are a plus.
• An understanding of how cloud infrastructure supports production services.
• Some hands‑on experience with core AWS services such as EC2, VPC, ECS, RDS, and IAM, plus a basic understanding of cloud security and networking fundamentals (VPCs, subnets, firewall rules).
• Exposure to, or strong interest in, Infrastructure-as-Code tools (Terraform or similar) and version control such as Git.
• A basic understanding of CI/CD pipelines that enable automated, reliable delivery of infrastructure changes.
• Awareness of monitoring and observability concepts, including metrics, logging, and alerting.
• Basic scripting ability in a language such as Python, Bash, or PowerShell to automate operational tasks.
• Exposure to Microsoft 365 services such as Entra ID, Intune, Defender, and Conditional Access.
• Experience with Oracle RDBMS, Oracle middleware, or PostgreSQL.
• Some experience using Linux and Windows, including the command line; exposure to Ansible is a bonus.
• Familiarity to containers (e.g. Docker or Kubernetes) or ECS/EKS.

Responsibilities

• Help build and support the cloud infrastructure that underpins our SaaS products and internal tooling – this will be your primary focus.
• Support our Oracle RDBMS and middleware and our end user computing estate – for example, database patching and backups, user requests, and device management through Intune – learning these technologies and helping the wider team support them (no prior experience needed).
• Plan, implement and test solutions with growing independence, knowing when to ask for help.
• Learn how our infrastructure works and suggest improvements.
• Help build proof-of-concept solutions to evaluate new technologies.
• Write clear documentation so others can understand and build on your work.
• Learn from experienced engineers, who will mentor you on technology, architecture and best practices.
