Senior Network & Infrastructure Engineer (f/m/d)

JTL is one of the leading providers of e-commerce software in the German-speaking region — with around 450 employees across the group and more than 50,000 customers across a wide range of industries. We develop scalable, flexible solutions for the online retail of the future, from ERP systems to shop and marketplace integrations.

You'll join our Infrastructure & Platform team — nine people responsible for hosting and for on-premises and cloud infrastructure across multiple sites. We run production environments in our own data centers (DDU, Equinix colocation), at Hetzner, and in Azure. Networking isn't a side topic here — it's a core responsibility: you'll take dedicated ownership of everything network-related and be the team's central point of contact for it.


Your Responsibilities

• Configure and manage switches, firmware upgrades, and IPsec and OpenVPN tunnels
• Maintain the Wi-Fi infrastructure across all company sites
• Monitor and coordinate our Equinix colocation environment, and handle communication with the provider
• Maintain DNS zones and own network design and architecture
• Handle VPN helpdesk tasks and support network troubleshooting across teams
• Act as the interface to the ITA team for all cross-functional network topics
• Plan and implement routing between Azure and our DDU data center

• You have several years' experience configuring and managing network infrastructure (switches, routing, firewalling)
• You know IPsec and OpenVPN tunnels inside out — not just in theory
• You have experience with DNS management and Wi-Fi operations in multi-site environments
• You're familiar with colocation operations (e.g., Equinix or comparable)
• You work independently and in a structured way, and you communicate clearly — including with non-technical stakeholders
• Good German language skills (at least B2 level)

Nice to have

• Azure networking knowledge (VNets, VPN Gateway, routing)
• General Azure cloud experience (IaaS, VMs, storage, subscriptions)

• Remote-first within Germany, with the option to work remotely from eligible countries for up to 180 days per year
• Meal allowance of up to €115 net per month
• Ergonomic workspace allowance for your home office setup
• Regular team events, company-wide gatherings, and summer and Christmas parties to stay connected as a remote-first company
• EGYM Wellpass and JobRad subsidy
• Financial benefits including capital-forming payments (Vermögenswirksame Leistungen) and a company pension scheme
