Linux Systems Administrator / DevOps Engineer
The Environment
The company are a market-leading European financial technology company and transaction venue provider at the cutting edge of modern market infrastructure. Driven by a culture of positive disruption and high performance, we build and license highly innovative, cost-effective infrastructure technologies globally.
We operate a supportive, ambitious, and collaborative environment where automation is championed, and every engineer is empowered to make a direct technical impact.
The Role
We are looking for an ambitious Linux Systems Administrator or early-career DevOps Engineer who is ready to take a major step forward in their career. If you have a rock-solid foundation in Linux systems administration and a passion for automation, this is a rare opportunity to work on genuinely complex, low-latency infrastructure that most engineers at this stage rarely get to touch.
You will join a small, highly skilled DevOps team where you will be hands-on from day one. We are looking for a true tech enthusiast—someone who genuinely enjoys solving infrastructure problems, structures pipelines thoughtfully, and gets quiet satisfaction from a perfectly automated system.
Key Responsibilities
Infrastructure & Automation: Help build, scale, and automate on-premise infrastructure using Infrastructure-as-Code (primarily Terraform).
Container Platforms: Contribute to automation across containerised and bare-metal environments, expanding your footprint in Kubernetes and OpenShift.
Configuration Management: Write automated workflows using Ansible, Python, and supporting DevOps tools.
CI/CD & GitOps: Partner with Development and Infrastructure teams to implement new deployment workflows using modern container-native and GitOps patterns.
Architecture & Design: Actively participate in architectural discussions—we want you to form views, share ideas, and contribute to technical decisions.
Capacity & Operations: Manage Linux systems at scale, driving capacity planning across Development, QA, Test, and Production environments.
What You Bring
Linux Expertise: A solid, practical foundation in Linux systems administration (RedHat, CentOS, Rocky or similar) with strong command-line confidence.
Automation Instincts: Strong scripting skills using Bash and Python; exposure to Ansible or Terraform is highly advantageous.
Core Networking: A working understanding of TCP/IP, DNS, routing, load balancing, and firewalls to logically debug system issues.
CI/CD Tools: Familiarity with Git concepts and standard build pipelines (GitLab experience is a strong plus).
Container Exposure: Basic experience with Docker; any exposure to Kubernetes or OpenShift is a massive plus.
Passionate Mindset: Strong self-direction—personal projects or homelabs are highly valued and viewed as valid experience.
What You Will Grow Into
This role is specifically structured for rapid professional growth. In this position, you will develop deep, production-level expertise in:
Enterprise Kubernetes and OpenShift across complex, high-scale environments.
Advanced GitOps workflows and container-native deployment tooling (ArgoCD, Helm).
Large-scale infrastructure design patterns and low-latency databases (e.g., Elasticsearch, MySQL).
A highly sought-after, elite understanding of financial market technology infrastructure.
Location: London (Hybrid, minimum 3 days in the office)
Employment Type: Permanent, Full-time
Salary: £90/100k + Bonus + Benefits
