Mission Operations Manager

What You'll Work On

• Exercise Planning: Plan trials and exercises within our exercise programme, from component tests through to multi-system exercises, with clear scenarios, objectives and success criteria.
• Exercise Delivery: Run exercises on the ground, coordinating the people, systems and logistics involved so that each one delivers usable results.
• User Liaison: Act as the day-to-day contact for operational units. Build trusted working relationships and keep a steady flow of feedback between users and SE3.
• Operational Assessment: Assess how our systems perform in realistic conditions and document their operational value, limitations and integration needs in clear post-exercise reports.
• Requirements Capture: Translate user feedback and field observations into structured requirements that product and engineering can prioritise and act on.
• Programme Support: Supply the commercial team with operational evidence, demonstrations and field insight that help turn engagement into awarded programmes.
• Team Building: Help establish the processes, templates and ways of working that let the Mission Operations team scale as SE3 grows.

Your Profile

• You take ownership of outcomes and get things done without waiting for direction. You turn plans into well-run activities and hold yourself to a consistently high standard.
• You bring several years of experience in military operations, trials or capability development, ideally as a serving or former officer or NCO, or in a field or trials role with a defence supplier.
• You have a solid technical understanding of unmanned systems, autonomy or software-defined defence, and engage credibly with both engineers and operators.
• You're highly organised and comfortable running complex activities with many moving parts, often outdoors and under time pressure.
• You communicate clearly and build trust quickly with military users, partners and internal teams.
• You're willing to travel regularly across Europe and into other markets where SE3 operates.
• You speak native-level German and have full professional fluency in English, written and spoken. Given the nature of SE3's work in the defence sector, candidates must be eligible to obtain and hold the security clearance required for this role.

Especially Valued Bonus Skills

• Experience planning or running military exercises, trials or experimentation campaigns involving unmanned or autonomous systems.
• Hands-on experience operating drones, with EU UAS operator certificates a plus.
• Experience in NATO or other multinational exercise environments.
