What is it like working in Systematic Defence?

Your code keeps the lights on

What if the software you build tomorrow helped coordinate a rescue operation, secure a national border, or keep a city's power grid running through a cyberattack?

At Systematic's National Security and Critical Infrastructure department, this is not hypothetical. It is what we do today.

Hybrid warfare, cyberattacks, and climate-driven disasters are no longer edge cases - they are the operating environment. Societies depend on systems that work under pressure, at scale, without fail. Governments, police forces, emergency services, and critical infrastructure operators are under threat, and they need technology that holds.

We are the people who build that technology.

Whether it is coordinating a multi-agency crisis response in real time, enabling border officers to run biometric checks against international criminal databases, or giving a utility operator situational awareness across an entire energy grid - our software sits at the intersection of engineering excellence and societal impact.

Battle-proven in Defence

We build software products for deployment in mission-critical environments where downtime is not an option, and a bad UX decision can cost lives.

Our roots are in Defence. Decades of delivering interoperability and situational awareness for NATO and allied forces gave us something most software organisations never develop: an instinct for reliability under adversity. We brought that same engineering discipline into National Security and Critical Infrastructure - and it shows.

Today, our solutions power:

Next-generation crisis management platforms giving emergency services a unified operational picture across the entire chain of command

Border control systems supporting 12,000 Danish officers with real-time biometric identification at Schengen external border
Critical infrastructure protection for energy, utilities, healthcare, and transportation, with advanced situational awareness that enables operators to anticipate threats, not just react to them

Police coordination systems like the HS2 platform used by Copenhagen Police, which handles up to 400 emergency calls daily and enables officers to manage more than twice as many simultaneous major events compared to traditional systems.

What this means for you as an IT professional

If you are a software developer, architect, tester, or project manager who wants to leave a mark - not just on a codebase, but on the societies that depend on it - this is where that happens.

You will work on systems where correctness matters. Where the architecture decisions you make today shape how fast a rescue unit responds tomorrow. Where a well-designed interface means empowering those at the center of it all in a high-pressure situation gets the right information at the right moment.

You will work with real users in real operational environments. Our colleagues work embedded with customers - not from a distance. That proximity means shorter feedback loops, deeper domain understanding, and the satisfaction of seeing your work used by people who depend on it.

You will be part of a team that takes its craft seriously. We value technical mastery, systems thinking, and the courage to challenge how software is built. We build things that last - and we hold ourselves to that standard.

Working at Systematic

A common feature of these core business areas is a need to integrate, compare and analyse large volumes of complex data, and to generate an overview that allows decision-making based on a solid foundation, often in critical situations.
