• Lead operational anomaly investigations, recovery activities and on-call support to ensure critical mission systems remain available and effective.
• Develop, maintain and enhance monitoring and trending tools using technologies such as Python, Perl, Linux and Grafana.
• Review, update and validate operational procedures, documentation and training materials for current and future system generations.
• Support future system development activities, assessing operational impacts and contributing to design and engineering working groups.
• Provide technical leadership and mentoring to engineers across the team while driving process improvements and operational excellence.

We're interested in candidates who can demonstrate:

• A degree in a STEM discipline (Science, Technology, Engineering or Mathematics) and relevant engineering experience, or equivalent qualifications as outlined within the role requirements.
• Experience working within systems engineering, operations engineering or a related technical environment.
• Strong knowledge of Linux environments and scripting tools such as Python, Perl or similar technologies.
• Experience analysing system performance, operational data trends and complex technical issues.
• The ability to work effectively across geographically dispersed teams and matrix organisations.
