Apply structured problem-solving skills to investigate and resolve technical issues across production and non-production environments.
Own and deliver regular maintenance activities such as system patching, upgrades and general platform housekeeping.
Diagnose and address system performance issues, identifying bottlenecks and implementing improvements.
Develop and maintain automation using scripting languages such as Python and tools like Ansible and Terraform to manage infrastructure and deployments.
Build, support and test infrastructure components as part of a collaborative engineering team.
Contribute to the design and implementation of observability and resilience practices to improve system reliability.
Participate in incident response, troubleshooting and root cause analysis to enhance system stability and prevent recurrence.
Work with CI/CD pipelines (e.g. GitLab CI or GitHub CI) to streamline build, test and deployment processes.
Use containerisation technologies, particularly Docker, to package and run applications consistently across environments.
Follow agile working methodologies, taking ownership of user stories and driving them through to completion.
Continuously identify opportunities for system improvement, automation and simplification, and implement agreed changes.
Collaborate closely with developers and other engineers to ensure infrastructure and applications work seamlessly together.

Solid knowledge of Linux systems, including deploying, maintaining and upgrading Linux-based servers, and working confidently in terminal-based environments.
experience with Linux distributions such as Red Hat Enterprise Linux or CentOS (or similar).
Proficiency in scripting or development using languages such as Python.
Practical experience with infrastructure automation technologies such as Ansible and Terraform.
Hands-on experience with CI/CD pipelines using tools such as GitLab CI or GitHub CI.
Strong experience with Docker and container-based workflows.
Familiarity with agile methodologies and working practices.
Understanding of observability and resilience concepts within an SRE context.
Additional Skills & Qualifications
experience contributing to the design and implementation of new technologies and platform solutions.
Exposure to resilience engineering practices, including designing for fault tolerance and graceful degradation.
experience implementing or working with observability tooling and practices (e.g. logging, metrics, tracing).
Ability to work closely with development teams to align infrastructure and application delivery.
Strong sense of ownership, with the determination to see tasks and user stories through to completion.
Clear, concise communication skills for collaborating within cross-functional teams and documenting solutions.
Why Work Here?
You will join a technology-focused environment where reliability, automation and modern engineering practices are at the core of how systems are built and run. The organisation offers the opportunity to work on large-scale, cloud-native platforms with contemporary tooling, giving you scope to deepen your SRE expertise and broaden your cloud and automation skills. You can expect a contract of at least one year with strong potential for extension, providing stability while you contribute to meaningful, high-impact projects. The culture encourages continuous improvement, knowledge sharing and collaborative problem-solving, supporting your professional growth in a modern engineering setting.
Work Environment
You will work in a cloud-centric environment built primarily on AWS, supporting high-volume, high-speed data systems. The technology stack includes Linux (such as Red Hat Enterprise Linux or CentOS), Python, Ansible, Terraform, Docker and CI/CD pipelines using GitLab CI or GitHub CI. The team follows agile methodologies, working in iterative cycles with user stories, regular ceremonies and close collaboration between developers and reliability engineers. Day-to-day work is hands-on and terminal-focused within Linux environments, with a strong emphasis on automation, observability, security and resilience.
