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.
This is a hands-on engineering role combining production support with continuous platform improvement. You will take ownership of the Linux environment across the APAC/EMEA operating day, working closely with colleagues in London and New York as part of a global follow-the-sun support model.
A key focus will be improving the environment through Linux patching, automation, scripting and reducing repetitive manual processes. This is an engineering-focused position rather than a traditional ticket-based support role.
Key Responsibilities
- Monitor, maintain and support a business-critical Linux production environment.
- Proactively investigate and resolve production incidents, taking ownership through to resolution.
- 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.
Essential Skills & Experience
- 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.
Desirable Experience
- 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.
