Linux Site Reliability Engineer

Initially 4 days per week onsite, reducing to 2 days per week onsite over time.

My client in the financial sector are seeking 2 Linux Site Reliability Engineers to join a global engineering team supporting a sophisticated, business-critical trading platform.

The organisation operates a complex, globally distributed technology environment supporting systematic trading activity. The Linux estate is central to its operations, with a strong focus on availability, resilience, security and performance.

• Troubleshoot Linux, infrastructure and platform-related issues.
• Manage Linux patching and lifecycle activities across on-premise and cloud environments.
• Develop scripts and automation to improve operational efficiency and eliminate repetitive manual processes.
• Utilise monitoring and observability tools to maintain platform health and identify potential issues.
• Participate in regional handovers and a global follow-the-sun support and on-call rota.
• Collaborate with infrastructure and engineering teams to continually improve platform stability and resilience.

• Background in Linux engineering, production support, platform engineering or SRE.
• Strong hands-on Linux administration and troubleshooting skills within a production environment.
• Ability to support highly available, business-critical infrastructure.
• Strong scripting skills using Python and/or Bash.
• Demonstrable ability to develop automation and improve operational processes.
• A proactive engineering mindset, with the ability to investigate and resolve issues independently.

• Experience working with AWS or other public cloud environments.
• Knowledge of monitoring and observability platforms.
• Experience with infrastructure automation.
• Previous experience within financial services, trading, investment banking or other low-latency technology environments.
• Experience working within a global 24x7 support model.
