Security Manager at Twentyfour Industries GmbH

What we’re looking for

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.
