Internship - Junior Software Developer (CPH)

Internship – Software Developer for Defence (CPH)

Are you passionate about coding and solving complex problems — and aspiring to develop software solutions that truly make a difference? At Systematic, we offer an exciting and well-established internship where your skills are valued, your ideas are heard, and your professional development is a priority.

Expected start: February 2027

Your role as a Software Developer Intern

As a Software Developer Intern at Systematic, you will contribute to meaningful projects — whether developing scalable web solutions, building standalone applications, or enhancing existing systems. You will gain hands-on experience with tools and technologies such as Java, Angular, Python, Kafka, Docker, Kubernetes, Apache NiFi, Open Search and much more.

Your daily tasks may include:

• participating in Scrum meetings and contributing to sprint planning and reviews
• assisting with the development of prototypes and innovative solutions
• collaborating with developers, testers, architects, and other team members
• improving existing software and development processes
• documenting software components and creating technical notes
• supporting customer-facing solutions and troubleshooting issues

Who we are looking for

We envisage that you are currently studying a Bachelor of Engineering in Software Technology or similar and that you are eager to apply your skills in practice.

You are likely to thrive in this role if you:

• work systematically, write clean code, and maintain a strong focus on quality and detail
• enjoy coding and take pride in using software to solve real-world problems and make a difference
• are curious and willing to learn new tools, frameworks, and methods
• take initiative and are not afraid to suggest improvements or share new ideas
• communicate clearly in English, both written and spoken (Danish is an advantage but not a requirement)
• thrive in a collaborative environment, but can also work independently when required

This is a full-time internship lasting five months, starting on 1 February 2027. The position is paid if your study program allows.

To be eligible, you must be enrolled in a Danish study program and be based in Denmark during the internship period.

Life as an intern

Interns are valued members of our teams. From day one, you will be assigned a dedicated tutor or mentor who will guide your development and provide ongoing support. You will work alongside experienced colleagues eager to share their knowledge, while being entrusted with real responsibility early in your journey.
We believe in delivering high-quality solutions while maintaining a positive work environment – whether through shared laughter over coffee, engaging discussions, or meaningful connections with colleagues. Beyond your immediate team, you will join our intern network, where you can build relationships and participate in social events with other interns across the organization.

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