Site Reliability Engineer

Job Title: Site Reliability Engineer

Job Description

This Site Reliability Engineer role focuses on designing, building and maintaining cloud-based, high-volume, high-speed systems that provide critical data services to the insurance industry. You will work primarily in AWS, using Linux, containers and modern automation and CI/CD tooling to improve reliability, performance and security. The position combines hands-on engineering, incident response and continuous improvement of the platform and its supporting infrastructure.

Responsibilities

• Design, implement and support scalable, resilient cloud-based solutions in AWS for high-volume, high-speed data systems.
• 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.

Essential Skills

• Proven experience in a Site Reliability Engineer (SRE) role, working on production systems.
• Previous industry experience working in a team that supports, builds and tests infrastructure.
• Background in software development, with the ability to understand and work with application code and tooling.
• Strong hands-on experience with AWS or other major cloud platforms in a production environment.
• 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. The setting is professional and technology-driven, with modern tooling and processes that support efficient remote collaboration and focused engineering work.
