The role

Within our client, the Networks & Datacenter department provides the secure and robust infrastructure upon which the bank's business-critical services rely.

A compact and focused project team has been set up for a strategic Extranet migration program. It consists of a project manager, a network engineer, and you as a firewall engineer. The team has short lines of communication and a clear goal, and your expertise is indispensable to achieve it.

What you'll do

As a Senior Firewall Engineer, you ensure that the migration of external connections is not only smooth, but also secure and compliant. You are responsible for the firewall policies, security measures, and network segmentation required to transfer the Extranet connections to the new environment. You work hands-on and collaborate closely with the network engineer and the security stakeholders. Your results are directly visible in a renewed, better-secured infrastructure.

What you are going to do:

Designing and implementing firewall policies for Extranet connectivity
Executing the security changes required for the migrations
Reviewing, optimizing, and cleaning up firewall rulesets
Contributing to network segmentation and secure connectivity solutions
Analyzing and resolving firewall and connectivity issues
Participating in testing, cut-overs, and post-migration support
Ensuring that everything complies with the bank's security standards and governance processes
Where possible: automating with Python, Ansible, or APIs

You are an experienced security specialist who prefers to be hands-on. You have sharp analytical abilities and maintain an overview in complex environments.
