Job description

The Role

As our Junior Infrastructure Engineer, you will:

• 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.

What you’ll bring

• A proactive, self‑starting attitude and a willingness to ask questions.
• Curiosity and an appetite for exploring new technologies.
• A genuine enjoyment of learning from others and sharing what you learn.
• A belief that constant improvement underpins good engineering.

Requirements
Essential:

• 1–2 years’ experience in an infrastructure, cloud, or IT operations role, or a relevant degree plus around a year of industry experience (for example, a 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, alongside a basic understanding of cloud security and networking fundamentals (for example, VPCs, subnets, and firewall rules).
• Exposure to, or a strong interest in, Infrastructure-as-Code tools (for example, 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 and workflows.

Desirable:

• 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 (for example, Docker or ECS, our current platform) or Kubernetes/EKS.
