Mandatory Internship (Pflichtpraktikum) - Software Engineering (3-6 months)

Our Mission

At constellr, we're harnessing the power of space to solve one of Earth’s greatest challenges: climate resilience & security in a changing world. Our thermal satellite constellation delivers the most accurate land surface temperature data on the market, equipping commercial players, governments, defence agencies, and global institutions with the thermal intelligence they need to make strategic decisions– from national security and infrastructure to agriculture and climate resilience.


As a fast-scaling company with offices in Brussels, Freiburg, Munich, Washington and Toulouse, our multidisciplinary team of engineers, scientists, and strategists is building the future of space-based Earth observation

Location: This position is offered on a hybrid basis in our Freiburg office, Germany - working closely with colleagues in the engineering team.

Your Role

This position is offered exclusively as a mandatory internship (Pflichtpraktikum) that is a required component of a university degree program under German higher education regulations.

The internship is designed as a learning-oriented educational placement , with close supervision and mentorship, and does not replace a regular employee role .

As a Software Engineering Intern, you will support the Satellite Technology team in improving internal software tools and documentation systems used in satellite development.

You will gain hands-on exposure to real-world engineering workflows while being guided by experienced engineers throughout the internship.

Key Responsibilities

• Support the maintenance and improvement of internal systems engineering documentation platforms

• Assist in building automation tools for requirements management, task tracking, and visualization

• Help integrate external data sources via APIs

• Support engineers in using and improving internal documentation and tooling

• Contribute to improving internal engineering workflows and processes

All tasks are performed under supervision and are aligned with the educational objectives of the internship.

What You Will Learn

• How software supports space systems engineering workflows

• How satellite development teams manage requirements, documentation, and engineering data

• How automation tools are built for engineering teams

• How modern engineering teams collaborate using DevOps tools and documentation platforms

• How software tools support real satellite missions and engineering processes

About you

• Currently enrolled at a university or university of applied sciences

• Your study program explicitly requires a mandatory internship (Pflichtpraktikum)

• Field of study: Computer Science, Software Engineering, Aerospace Engineering, or a related discipline

Required Skills

• Basic Python programming skills
