What we do (and why it matters):

Swarmer develops software that makes drones autonomous and allows them to operate together, in large teams, without pilots required. Our technology has been battle-tested across 100,000+ combat missions in Ukraine — the world’s most intense proving ground for drone warfare. We just closed a $15M Series A (the largest investment in Ukrainian defense tech since the war began) and we’re scaling operations to serve NATO-aligned nations.

This isn’t theoretical. This is software that’s being used right now to save lives and defend democracy.

What we’re looking for:

We are looking for a Director of Physical Security who will take full ownership of building and leading our physical security function. This role is about creating a modern, multi-layered security framework that safeguards our people, offices, and technologies. You will ensure that Swarmer not only meets the highest security standards but also builds a proactive, risk-driven security culture across the organization.

You’ll be a good fit if you have:

• 5+ years of experience in corporate, defense, or government-related security roles.
• Proven track record of building security systems end-to-end (not just executing, but shaping strategy and vision).
• Strong knowledge of the physical security domain.
• Structured, risk-oriented mindset with the ability to see consequences and drive systemic change.
• Modern approach to security — using contemporary tools, methodologies, and international standards.
• Fluent in English (spoken and written).
• Ability to work with senior leadership and influence decision-making.

What you’ll do:

• Develop and lead a comprehensive corporate security strategy covering physical security, operational resilience, and personnel protection.
• Ensure the security of offices, facilities, and employees, including access control, surveillance, and incident response procedures.
• Maintain close cooperation with Ukrainian, Polish, and American defense, security, and regulatory bodies to ensure compliance and effective security operations.
• Work alongside Legal and HR to ensure rigorous background check processes, adherence to data privacy regulations, and secure hiring practices (including background management where applicable).
• Build internal awareness and training programs to foster a culture of security across the organization.
• Anticipate risks, assess vulnerabilities, and proactively initiate systemic changes to strengthen our resilience.
• Establish and maintain security standards that align with international best practices.

What you’ll get:

• Professional growth through working with cutting-edge defense technologies and exposure to international security best practices.
• A fast-paced environment with minimal bureaucracy and no “process for the sake of process”.
• Competitive salary and a comprehensive benefits package (insurance, paid sick leave, 20 paid days off per year).
• Benefits of the defense sector (e.g., reservation, etc.).
• Flexible remote work options where possible.

How’s the hiring process going:

✔️ Intro Call → ✔️ Interview with VP of Operations → ✔️ Interview with Security Consultant → ✔️ Final interview with CEO → ✔️Security check → ✔️Offer

Why this matters (and why you should care):

Ukraine is deploying 5 million drones in 2025 alone. The US and NATO are paying attention. The future of defense isn’t more pilots—it’s smarter software. We’re not selling PowerPoints; we’re selling proven technology that’s been refined under the most demanding conditions imaginable.

Our team is direct, moves fast, and doesn’t waste time on performative nonsense. If you want a company with seven layers of approval and endless consensus-building, this isn’t it. If you want to do the most important work of your career with people who say what they mean and execute, let’s talk.

At SoftButler, we focus on building quality into every stage of development.
