IT Systems Engineer

About Astrape Networks Astrape Networks is rebuilding the nervous system of the AI data center. Today's AI clusters run three or four parallel networks because no single fabric is fast or flexible enough. We collapse them into one adaptive fabric that fuses optical and electronic switching and decides, flow by flow and at microsecond speed, how data should travel. The result is up to 60% less energy, 50% more traffic, and a network that scales to millions of GPUs. Role Overview As our first IT & Systems Engineer, you'll build Astrape's IT from the ground up. You won't be setting up spreadsheets for accountants. You'll be supporting a team of engineers who live on Linux and Mac, and who need infrastructure that's fast, secure and always on. Your work rests on three pillars. First, security: you'll lock down our VPN, set up single sign-on and two-factor authentication, and make sure every device is encrypted and managed. Second, our operational servers: the Git repositories, Jenkins and the other systems our engineers rely on every day, spread across Belgium and the Netherlands, with backups that run automatically, both locally and in the cloud. Third, day-to-day support, from lost passwords to email issues and a Wi-Fi network that needs fixing. You'll also be the technical point of contact for our external auditor and IT security partner. We're a small company growing fast, so this role grows with us. Today you're the first. Soon you'll be building a team.
