Network & Security Engineer (m/w/d) – Extreme, Fortinet oder Unify

Why does this vacancy exist Networks are the nervous system of any IT infrastructure, and that is our specialty. For customers from the automotive, medical, software, and manufacturing industries throughout Baden-Württemberg, we plan and operate secure network and voice infrastructures with a clear focus on the manufacturers: Extreme Networks, Fortinet, and Unify. As a long-standing partner of these manufacturers, we have direct contact, the best conditions, and access to first-class training and events. That's why we're looking for you. Important: We are filling this position according to your qualifications — and you don't need to be an expert in all three manufacturers. Regardless of whether your main focus lies in switching and WLAN, firewalls, or voice communication: we will tailor the position to your strengths and develop the rest together.

Your role – four focal areas (typical distribution – your actual mix will depend on your focus) Implementation of network projects (approx. 40%): You plan, configure, and document switching, routing, and WLAN infrastructures with Extreme Networks — including network segmentation and NAC solutions for complex environments. Security (approx. 25%): You implement and operate FortiGate firewalls, SD-WAN, and VPN solutions, and develop security concepts together with our security specialists. Operation and troubleshooting (approx. 20%): You monitor network infrastructures, handle incidents and problems, systematically search for errors across OSI layers 1–7, and automate recurring tasks. Voice and UC (approx. 15%): You manage and migrate voice communication solutions based on Unify OpenScape and integrate them with modern solutions like Teams telephony.

On what basis will we measure success together after 12 months You independently implement rollouts of network solutions (switching/WLAN) — from planning to documentation Manufacturer certification completed (e.g., Fortinet FCP/NSE or Extreme ECS) You have participated in a segmentation or NAC project In troubleshooting, you are a reliable specialist the team can count on We will define specific goals together — depending on your starting level.

What you bring with you Hands-on experience in network administration (switching, routing, VLAN, firewalls) — it doesn't matter if it's with Extreme, Fortinet, Cisco, HPE/Aruba, or other manufacturers. 1–2 years are sufficient, more is welcome. Confident handling of TCP/IP and a structured approach to troubleshooting Responsibility and a hands-on mentality — networks don't forgive mistakes Fluent German, good English skills (manufacturer documentation), and a Class B driver's license

What we do NOT expect Cisco certification. We work with Extreme, Fortinet, and Unify — we will obtain manufacturer certifications together, at our expense, including training and manufacturer events. Experience with all three manufacturers — one is enough. Even with experience in Cisco or Aruba only, you fit us: network skills are transferable, we will acquire manufacturer-specific knowledge together. Programming skills — you will learn automation from us. We are more interested in where you want to go than where you come from. Motivation is more important than experience.

Your development path Structured onboarding with 30- and 100-day meetings, a personal mentor from the network engineering team, manufacturer certifications paid for by us (Extreme, Fortinet, Unify), including national and international manufacturer events, as well as training programs from our indasys Academy. Your prospects: Senior Engineer, Network and Security Architect — or technical leadership of our network business.
