Security Manager - #2674306

What We’re Looking For

We are looking for a clear-headed and experienced Security Manager to own the protection of our sites, our people, our information, and our communication. In this role, you will be responsible for a coherent security concept that satisfies customer, national, and NATO security requirements, and that enables us to run classified and export-controlled work without friction. This is an ownership role with real authority and a direct line to the COO. You grant and withdraw access, you set the rules that apply on every site, and you can stop any activity that creates unacceptable exposure.

The day-to-day

• Security concept and governance: own the company-wide security policy, the threat and risk assessment, and the security posture our defense customers and programs demand.
• Location security: own physical security across all sites: access control, zoning, alarm and surveillance systems, visitor handling, key management and restricted areas.
• Communication security: own secure communication and classified information handling: approved channels, encryption standards, storage and transmission rules.
• Personnel security: own vetting, security clearances, briefings and offboarding for everyone with access to sensitive material.
• Incident response: own detection, reporting and investigation of security incidents, including notification to customers and authorities.
• Awareness and training: run recurring security briefings so every employee knows exactly which rules apply to their role.
  
  

You should apply if you

• Education: you have completed vocational training or a degree in security management, safety and security engineering, political science or international security studies, law, business administration, information security, or you bring a comparable military or police background.
• Experience: you bring at least 3 years in corporate, industrial or military security, ideally in a defense, aerospace or critical infrastructure environment.
• Frameworks: you have worked hands-on with national and NATO security requirements, classified information handling, and personnel security clearance processes.
• Practice: you are comfortable across the full field: physical security concepts, access and zoning, incident investigation, and security briefings that people actually remember.
• Mindset: you like building the system, not inheriting it. You are comfortable in a fast-moving start up where the process does not exist yet, and you have the backbone to stop an activity when the risk is not acceptable.
  
  

Nice to haves

• Clearance: an existing personnel security clearance (Ü2/Ü3) or eligibility for one.
• Authority experience: working relationships with BMWK, BAAINBw, national security authorities or customer security officers.
• Adjacent domains: exposure to export control, IT and cyber security, or business continuity and crisis management.
  
  

What We Offer

• Real impact & ownership: Shape high-tech defense systems and take responsibility from day one.
• Mission-driven environment: Work on technologies that matter for European security and sovereignty.
• Competitive package: Competitive salary, EGYM Wellpass, corporate benefits, and equity options aligned with role and level.
• Deep tech environment: Get hands-on experience with cutting-edge drone technology and real operational use cases.
• Grow fast: Steep learning curve for juniors, strategic influence and leadership opportunities for seniors.
• Startup mindset meets defence innovation: flat hierarchies, fast decisions, and space for your ideas.
• Flexibility: Flexible hours, remote options, and relocation support.
• Strong team: International, driven colleagues and a culture built on exchange, trust, and shared success.
