• Lead technical troubleshooting during operational issues, anomalies, test campaigns, rehearsals, and mission readiness activities.

• Support Orbit Determination and Analysis, Mission Planning, and related operational products by coordinating inputs, validating outputs, resolving support issues, and ensuring planning data is operationally usable.

• Drive operational automation improvements by identifying opportunities to improve monitoring, alerting, troubleshooting workflows, data checks, reporting, and overall support efficiency.

• Coordinate issue resolution across mission operations, spacecraft engineering, ground segment engineering, flight software, IT, cyber security, vendors, and external service providers.

• Own and improve support processes, including incident management, escalation paths, root cause analysis, corrective actions, and support readiness.

• Lead the creation, review, and improvement of support documentation, troubleshooting guides, operational procedures, training material, and knowledge base content.

• Support the training and mentoring of Support Engineers, operators, and new joiners, helping build team capability and operational confidence.

• Monitor recurring issues, system trends, support metrics, and operational risks, recommending improvements to reduce failures and improve reliability.

Skills and Requirements

• Strong experience in satellite operations, ground segment operations, mission control systems, systems support, or another high-reliability technical environment.

• Proven ability to troubleshoot complex technical issues across operational systems, interfaces, infrastructure, data flows, and support tools.

• Good understanding of mission operations concepts, including routine operations, anomaly response, maintenance, readiness, testing, and operational handover.

• Experience leading issue investigation, root cause analysis, corrective action tracking, and stakeholder coordination.

• Ability to create and improve technical documentation, procedures, support guides, training material, and operational knowledge bases.

• Strong communication and coordination skills, with the ability to work across technical teams, operational teams, vendors, and management.

• Ability to mentor junior team members and provide technical leadership during operational support activities.

• Strong operational judgement, with the ability to prioritise issues based on mission impact, system criticality, and operational risk.

Nice to Have
