This is an exciting opportunity to work on an impactful product within a critical domain –you will have the chance to contribute to architecture and system design together with a diverse and highly skilled team, working with a broad technology stack focused on quality, security and performance.

What you will be doing
As a key member of our development team, you will play a central role in delivering projects with new functionalities and enhanced versions of our product. You will take ownership of feature deliveries from initial concept through to final release, ensuring high quality and alignment with customer needs.

• Implement, test and deliver new functionality and change requests across the stack
• Work closely with your team-mates to review code and ensure we maintain a high level of code quality and consistency
• Share knowledge, challenge solutions constructively and contribute to continuous improvement within the team

The team
Our work centres on SitaWare Headquarters – an advanced and operationally proven C4ISR solution. The system enables seamless collaborative planning, tactical communication and real-time situational awareness across all command levels and domains. 

You will be joining our HQ programme, a collaborative set-up of around 75 skilled colleagues based in Aarhus and Bucharest.
