Customer Operations Engineer 24/7(f/m/d)

At IONOS, the leading European provider of cloud infrastructure, cloud services and hosting services, you will work together with a wide range of teams. We are characterized by open structures, a friendly working culture and flat hierarchies with a strong team spirit. We firmly believe that work and fun are compatible, and offer you the right environment for this. Our constant growth means that we are always looking for new colleagues. Become part of IONOS and grow with us.

We are looking for experienced Cloud Operations Engineers with strong backgrounds in Linux, Windows, networking, and cloud environments to join our Customer Operations team.

You will support our Business and Enterprise customers across the full lifecycle of incident handling from initial intake and root cause analysis through to full service restoration. You bring a customer-first mindset and a strong drive to solve complex problems. While we receive requests directly from customers, we operate as an L2/L3 team. You are comfortable managing multiple tasks simultaneously and can set clear priorities even under pressure.

We operate 24/7 across three shifts. You are comfortable participating in shift rotation and being scheduled accordingly. Some of our work touches sensitive areas; you are willing to undergo an extended security vetting process (SÜ2). Our customers communicate in both German and English, and you are equally confident in both.
