Senior Network Engineer

Within our client, the Networks & Datacenter department forms the foundation of the entire IT landscape. This department provides secure, scalable, and robust infrastructure upon which thousands of applications, users, and business-critical processes run daily.

A compact and decisive project team is being set up for the migration and modernization of the Extranet landscape. The team consists of a project manager, a security engineer, and you. Not a large, cumbersome organization, but short lines of communication, a clear goal, and colleagues who know their craft. Your expertise will make a direct difference here.

As a Senior Network Engineer, you are the technical linchpin of the Extranet migration. You are both the subject matter expert and the one who rolls up their sleeves. You translate project goals into a concrete design, execute the migration, and ensure that everything runs stably after the transition. You work in an environment where availability and security truly matter, and you see the result of your work reflected in a renewed, future-proof infrastructure.

What you are going to do:

• Designing, preparing, and executing Extranet connectivity migrations
• Analyzing current network connectivity and developing the target design
• Configuring and managing Cisco Nexus infrastructure
• Implementing changes according to the bank's change and governance processes
• Resolving complex network issues and performing root cause analyses
• Guiding testing, validation, cut-overs, and stabilization after migration
• Where possible: automating with Python, Ansible, or APIs and thinking along about Infrastructure-as-Code and lifecycle management. If you are already working with these, you will be given plenty of room to advance them further.

You are an experienced network specialist who enjoys building things yourself. You combine strong analytical and troubleshooting skills with a structured, project-based approach.
