Company description

ATMOS was founded as a European company built on the values of freedom, democracy, equality, the rule of law, and human rights. We are committed to protect these values by making our technology available to others who share the same values, strengthening infrastructure and innovation for prosperity on Earth.

Our team is multinational and diverse, with offices in Lichtenau and Strasbourg. We work in a collegial, hands‑on culture where people support each other, take ownership, and keep learning every day.

This principle shapes our work environment where exceptional people, as committed as they are competent, can grow and contribute to a mission that matters.
