The Role

They're looking for an ambitious DevOps Engineer ready to take the next step in their career. This is an opportunity to work on genuinely interesting infrastructure within a fintech environment where technology plays a critical role in the business. Whether you have a strong background in Linux systems administration or you're already working in a junior DevOps capacity and looking to deepen your expertise, you'll have the opportunity to develop quickly and work with technologies that are difficult to find elsewhere. You'll join a small, highly skilled DevOps team and be hands-on from day one. You'll work alongside experienced engineers, take ownership of meaningful projects and contribute to the evolution of a sophisticated on-premise and containerised infrastructure environment. This role will suit someone who is naturally curious about technology - someone who enjoys automation, likes understanding how systems work, and takes satisfaction in building infrastructure that is reliable, scalable and well engineered.

What You'll Be Doing

• Build and automate on-premise infrastructure using Infrastructure-as-Code tools, primarily Terraform, with an increasing focus on container platforms and Kubernetes/OpenShift.
• Develop automation across containerised and on-premise environments using Ansible, Python and supporting tooling.
• Work closely with Development and Infrastructure teams to introduce new technologies and workflows into production.
• Develop your knowledge of container-native and GitOps deployment patterns.
• Contribute to architectural discussions and have a genuine voice in technical decisions.
• Support internal teams with CI/CD pipelines, build systems and developer tooling.
• Work with Linux systems at scale, including deployment, configuration management and systems operations across containerised and virtualised environments.
• Contribute to capacity planning and help ensure container platforms remain scalable across Development, QA, Test and Production environments.
• Create and maintain clear, useful technical documentation.
• Troubleshoot complex infrastructure and operational issues while developing a deep understanding of the wider technology estate.

What We're Looking For

You'll ideally have:

• A strong foundation in Linux systems administration, ideally Red Hat/CentOS or a similar environment.
• Confidence working from the command line and a good understanding of how systems and infrastructure fit together.
• Experience or a strong interest in scripting and automation, particularly Bash and Python.
• Exposure to Ansible and/or Terraform.
• Familiarity with Git and fundamental CI/CD concepts; experience with GitLab would be advantageous.
• A working understanding of core networking concepts including TCP/IP, DNS, routing, load balancing and firewalls.
• Some experience with containers, particularly Docker.
• Exposure to Kubernetes or OpenShift would be highly beneficial, but isn't essential.
• Clear, pragmatic written and verbal communication skills.
• A genuine interest in technology and a desire to keep learning.

We're also interested in what you've built outside of work. Personal projects, home labs and self-directed learning are absolutely relevant - if you've built something interesting because you wanted to understand how it worked, we'd like to hear about it.

What You'll Learn

This role offers significant scope for technical development. You'll have the opportunity to build expertise in:

• Kubernetes and OpenShift across complex on-premise environments.
• GitOps workflows and container-native deployment pipelines, including ArgoCD and Helm.
• Infrastructure design patterns and configuration management at scale.
• A broader technology stack including QuestDB, Elasticsearch and MySQL.
• The infrastructure and technology supporting low-latency trading environments.
• The operational and technical requirements of modern financial market infrastructure.

Why Join?

This is a chance to join a technically ambitious organisation where DevOps is more than simply maintaining servers and pipelines. You'll have the opportunity to work with experienced engineers, contribute to architectural decisions, automate at scale and develop expertise across infrastructure, containers, Kubernetes and financial technology. If you're technically curious, enjoy solving problems and want a role where you can make an impact while continuing to grow, this could be an excellent next step in your DevOps career.
