## About the Role

* Strong Linux SysAdmin Foundation: Deep, hands-on experience administering RedHat/RHEL, Rocky Linux, or CentOS. You are comfortable on the command line and understand how systems fit together under the HOOD.
 * Core Networking Knowledge: Practical understanding of TCP/IP, DNS, routing, load balancing, VLANs, Firewalls, and TLS/mTLS certificate management.
 * Containerisation Experience: Proven experience deploying and troubleshooting containerised workloads (Docker/Podman as a minimum; hands-on Kubernetes or OpenShift is highly desirable).
 * Scripting & Automation: Strong Scripting skills in Bash and Python, alongside experience with Git for version control.
 * Communication: Clear, pragmatic communicator capable of writing solid runbooks/documentation and collaborating with both internal teams and external stakeholders.

Nice to Have

 * Hands-on experience with Infrastructure-as-Code and configuration management tools (Terraform, Ansible).
 * Experience with CI/CD and GitOps tooling (GitLab CI, ArgoCD, Helm).
 * Background within fintech, financial markets, or other regulated, low-latency environments.

## Description

Please note: This is strictly an infrastructure-first role. We are looking for engineers from a genuine Linux Systems Administration background who understand operating systems, networking, and bare-metal/virtualised internals-not application or software developers.

You will join a small, hands-on engineering function responsible for building, automating, and deploying mission-critical, low-latency containerised platforms across both internal on-premise environments and external client sites., * Linux & Infrastructure Automation: Build, configure, and manage complex Linux systems at scale across on-prem, virtualised, and containerised environments.

 * Container Platforms & Orchestration: Deploy, validate, and manage multi-service containerised applications across Kubernetes, OpenShift, Docker/Podman, and VMware platforms.
 * Infrastructure as Code (IaC) & Tooling: Drive automation initiatives using Terraform, Ansible, Bash, and Python to eliminate manual effort and standardise deployments.
 * Release & Environment Management: Translate release notes and configuration requirements into reliable, repeatable production and pre-production environments (using GitOps patterns, Helm, ArgoCD, and GitLab CI).
 * Troubleshooting & Root Cause Analysis: Diagnose complex OS-level, networking, and container issues across live and pre-production environments.
 * Client & Stakeholder Delivery (Managed Services track): Depending on your preference and skill set, either focus purely on internal platform engineering or take a client-facing role guiding external financial clients through on-site/remote setups, upgrades, and operational handovers.
