Senior Executive Assistant to the CTO (f/m/d)

Mission Brief

Isar Aerospace is building Spectrum, a European launch vehicle developed and tested in Germany. Engineering, testing and operations all need time with our CTO, so the CTO’s time is one of the most requested resources in the company. How well it’s organised directly affects how quickly technical and operational topics move forward.

That’s where you come in. You’ll run the CTO’s calendar, travel and meeting preparation, and make sure that what’s agreed in a meeting actually happens afterwards. You report to the Chief of Staff, who leads the content of meetings. You take care of everything around them and keep the Chief of Staff updated on what’s happening in the technical organisation.

Your Role in Our Space Mission:

• Run the CTO’s calendar. Schedule and reschedule, handle the daily flow of requests, and keep the week realistic. A big part of this is balancing the CTO’s time between technology and operations, with priorities agreed with the Chief of Staff.
• Prepare the meetings that matter, and follow them through. Decide with the Chief of Staff which internal, executive, technical and partner meetings take place. Prepare agendas, pre-reads and briefing packs, then follow up on every decision and action item until it’s done.
• Keep the commitment log for the CTO Office. Track open topics and decisions, flag anything at risk early, and make sure nothing gets forgotten.
• Keep the CTO Office routines running. Plan leadership meetings, technical reviews, offsites and selected company-wide events well in advance.
• Plan travel end to end: bookings, itineraries, documents and approvals, and expense reports afterwards.
• Get leadership materials ready to send. Collect inputs, keep numbers and formatting consistent, and give PowerPoint presentations and reports a final check before they go out.
• Keep information moving and fix what’s stuck. Make sure information flows both ways between the CTO Office and the rest of the company. Spot bottlenecks and either solve them or raise them with a proposal.
• Support special projects and improve how we work. Help with initiatives led by the Chief of Staff, from scoping to completion, and leave the CTO Office’s processes and templates better documented than you found them.

Qualification Checklist

• Several years as an Executive Assistant, Personal Assistant or in a similar role supporting senior leaders. Experience in a CEO or CTO office is a strong advantage.
• You can track several workstreams, deadlines and stakeholders at once, and you know what matters most.
• Ownership: you follow up without being asked twice.
• Clear, concise communication. You can sum up a complex topic briefly and precisely.
• Confidence with senior stakeholders, including turning down a request in a friendly, well-reasoned way.
• Comfort with modern productivity, collaboration and AI tools.
• Discretion. Technical, personnel and commercial information passes through your hands and goes no further than it needs to.
• Composure when plans change at short notice, and a hands-on attitude towards tasks outside your job description.
