IT Senior Network Administrator (m/f/d)

Who We Are

MBS operates satellites, ground stations, and secure communications networks to ensure that armed forces, government agencies, and businesses remain reliably connected anytime and anywhere.

As an owner-managed, mid-sized company specializing in satellite communications and space technology, we employ around 300 people across our locations in Germany, France, and Poland. With our own ground infrastructure, including the largest teleport in Germany, we have been developing and operating highly reliable satellite and data network communication solutions for government and industrial customers for over 45 years.

Working at MBS means making a direct contribution to Europe’s security infrastructure, with real responsibility from day one.

As a Senior Network Administrator (m/f/d), you are the backbone of our digital infrastructure. You manage data flows, connect systems, and ensure the stability of our network environment. You think in networks, not boundaries, and make sure our communications from Earth to space remain secure, fast, and reliable at all times. A moderate willingness to travel (approx. 10-15%, including visits to our headquarters in Usingen) completes your profile.
