• Maintain and enhance monitoring and alerting tools to proactively detect and respond to issues.

• Review incidents to identify trends and implement improvements to increase automation and operational efficiency.

• Develop and maintain documentation, support procedures, and best practices.

• Assist in managing system capacity, resilience, and scalability to support business growth.

What we’re looking for

• 1+ year of experience in production engineering, development or a similar technical role.

• Hands-on experience with scripting or development (e.g. Python, Powershell or similar) with an automation and tooling focus.

• Strong troubleshooting and analytical skills, with the ability to investigate issues through logs and system behaviour.

• Experience working with distributed systems, including understanding of networking fundamentals and system interactions.

• Experience with scripting or automation (e.g. Python, PowerShell, or similar).

• Exposure to monitoring and alerting tools (e.g. ELK stack, CheckMk, Nagios).

• Familiarity with database systems and data-driven applications.

• Experience working with ticketing systems and managing multiple concurrent support requests effectively while under pressure.

• Strong communication skills, with the ability to clearly explain technical concepts to both technical and non-technical stakeholders.

• Willing to support shift work and on-call responsibilities.

• Experience in financial systems or trading environments is beneficial but not essential.
