London Competitive base salary + performance-related buy side bonus

Linux Python Automation Networking Observability Performance Engineering

The Role:

This is an infrastructure engineering role within a technology-led investment business where the Linux estate sits close to live markets and directly supports business-critical systems.

You will take meaningful ownership of platform design, automation and performance. The environment is large-scale, technically demanding and built for engineers who prefer improving the platform over repeatedly fixing the same operational problems.

What You Will Be Doing:

• Engineer and improve Linux platforms supporting time-sensitive financial systems.
• Build automation that makes infrastructure deployment, configuration and maintenance more consistent.
• Investigate performance across operating systems, networks and applications, then implement practical improvements.
• Strengthen monitoring and observability so issues can be identified before they become business problems.
• Work closely with software engineering and operational teams on platform reliability, releases and production change.
• Influence technical direction, engineering standards and the longer-term development of the estate.

What You Bring:

• Strong Linux engineering knowledge, ideally gained in a large-scale or performance-sensitive environment.
• Hands-on ability with infrastructure automation and configuration management.
• Good Python and shell scripting skills, with the judgement to use code rather than manual processes.
• A solid understanding of networking fundamentals, including how systems behave under demanding traffic and latency conditions.
• Experience investigating system performance, reliability or capacity issues across more than one layer of the stack.
• A collaborative engineering approach, including source control, peer review and clear technical communication.

The Package:

Competitive base salary with a performance-related buy-side bonus and broader benefits package.

The position is London based. Further details on compensation and working arrangements will be shared during the initial conversation.
