Senior Linux Engineer

Your Team
The Infrastructure Platform Engineering team designs, builds and supports the Linux and cloud platforms that power critical business services across the organisation. We work closely with application, security and architecture teams to deliver secure, scalable and resilient infrastructure. Operating within Agile and DevSecOps ways of working, the team focuses on automation, standardisation and a cloud first strategy. Our role is to balance innovation with the high reliability and compliance standards required in a regulated financial services environment.
Your Role
As a Senior Engineer, you will be a hands on technical contributor responsible for building, operating and continually improving Linux based infrastructure platforms. You will apply strong engineering judgment to implement Infrastructure as Code, automation and cloud native practices. This role requires deep technical expertise, the ability to resolve complex, non routine issues independently and close collaboration with delivery teams. You will exercise independent judgement on technical decisions and clearly communicate complex technical concepts to both technical and non technical stakeholders, while providing informal technical guidance to peers.
You Will Be Responsible For:
Engineering and supporting Unix/Linux platforms across on premises and cloud environments using DevOps principles, with minimal supervision.
Building, maintaining and enhancing Infrastructure as Code solutions using tools such as Puppet, Ansible, Terraform, and Git.
Acting as a Unix/Linux subject matter expert within Agile delivery squads, helping shape technical approaches and resolving non routine platform challenges.
Developing and maintaining automation using modern scripting and tooling languages (e.g., Go, TypeScript) to reduce manual effort and operational risk.
Collaborating with application, cloud and security teams to design and implement secure, reliable and scalable Linux based solutions.
Ensuring systems are configured in line with security, regulatory, audit and operational resilience requirements.
Troubleshooting complex platform and infrastructure issues that impact business critical services.
Leading small technical initiatives or workstreams with manageable risk, contributing to platform standards, best practices and continuous improvement.
The Experience You Bring:
Strong enterprise level experience administering and supporting Red Hat Enterprise Linux environments.
Proven hands on experience with Infrastructure as Code and configuration management tools (Puppet, Git, Packer; Ansible and Terraform preferred).
Experience working with CI/CD pipeline tools (GitHub Actions, GitLab)
Experience working in hybrid environments, with solid exposure to AWS infrastructure and services.
Practical experience deploying, patching and maintaining Linux servers and/or containers using native tooling (e.g., Red Hat Satellite).
Familiarity with container technologies and cloud based SaaS, PaaS and IaaS platforms.
Working knowledge of security and identity platforms, including Privileged Access Management (PAM) solutions such as the Delinea Cloud Suite and how they integrate with infrastructure platforms.
Experience designing and supporting Linux workloads running on VMware, Nutanix or equivalent virtualised environments.
Familiarity with enterprise logging, monitoring and observability platforms such as Splunk.
