Senior Software Developer, Defence Bespoke 

Do you want to work with the full development cycle, from customer requirements to tested, tailored software, in a defence team where quality matters? Join our Bespoke team in Aarhus and build the extensions our customers need. 

The job 

In this role, you will help deliver customised add-ons, integrations and extensions to Systematic’s defence product suite, across the full development cycle – from analysing requirements and designing solutions to implementing, testing and troubleshooting them – and help continually improving the way we work. 

In short, you can look forward to: 

• Designing, implementing, documenting and debugging features across front-end and back-end 
• Building and troubleshooting interfaces to external systems and hardware, such as sensors and radio interfaces 
• Analysing requirements and breaking them into technical tasks with clear acceptance criteria 
• Writing unit and integration tests, taking part in code reviews and designing for testability 
• Sharing knowledge through close sparring and collaboration with colleagues and supporting the onboarding of less experienced colleagues 

Joining the team 

You will join the Bespoke Applications team: 18 developers, architects and testers, spread across Denmark and Poland. Together, we deliver software and hardware integrations – from sensor interfaces and radio drivers to interoperability with external systems – so that our customers get exactly the functionality they need, built to last. 

You will work closely with fellow developers, architects, testers and project management, and with hardware partners and external system providers. We value open collaboration, sharing what we learn and speaking up with ideas for how we can improve our code, tooling and processes. 

We already use AI in our daily work and want to explore it even further. Working in defence comes with policy and security considerations, but we are working to increase our gains from these new tools – and we need colleagues who are curious to join us on that journey. 

Your qualifications 

• Minimum a bachelor’s degree in engineering, Computer Science, Software Technology or similar 
• Minimum two years of experience in software development 
• Experience with Java or C# and Angular is a plus 
• Fluent English skills 

On a personal level, you: 

• Have strong analytical abilities and can communicate intent and purpose clearly 
• Work proactively and independently, and thrive in collaborative projects 
• Build good relationships and collaborate effectively with stakeholders 
• Are passionate about customer needs and how our systems are used 
• Share information proactively and help others learn through mentoring and workshops 
• Are curious about AI and eager to explore how it can help us work smarter within the boundaries of defence 
• Is interested to learn the needed technologies, the domain, and the lessons of past projects on how to succeed 

The role may include occasional travel of approximately 2–10 days per year, mostly within Europe. 

Please note that you must be able to present a clean criminal record and have lived in a NATO and/or an EU country for the past seven years as we work with security-classified projects. Read more here.
