Job description

We're looking to add an IT security engineer to our team. You'll join a team responsible for different Danske Bank infrastructure security components (Proxy, IDS, IPS, SandBox’ing, HSM, PKI, etc). Our team is also in charge of defining security baseline standards for IT infrastructure systems, their components and network.
This is a job for an analytical person with an IT security background and, ideally, infrastructure experience. We're looking for people with a genuine interest in current and evolving security threats, IT and information security, large IT environments, systems, and network infrastructure. The role will require you to work with applications and infrastructure teams on the promotion and adoption of infrastructure platform components and services. The main technical focus in this role will be intrusion detection (IDS) and protection systems (IPS) for networking and mainly for zOS.
As for you, you're a very systematic, focused, and analytical person with a developer mindset. You work equally well independently and on a team, and your winning attitude gets things done. Does that sound about right? Great—that's the kind of spirit we want on our team.
Check out the skills required for this role, and apply if you have the right stuff!
