Senior Network Engineer | Palo Alto, Public Cloud, Cisco | Mission-Critical Global Platforms
- Dublin, Docklands - 4 days onsite, 1 day from home
- €90,000 – €100,000 base 10-12% Bonus
- Permanent, Full-time
The role:
You will join a global Managed Services and Infrastructure team (2000 employees globally with a team of 10 in Ireland, growing month-by-month), responsible for securing large-scale software platforms used across healthcare, financial services and government environments worldwide.
This is a senior-level network security engineering role focused on designing and standardising security controls across hybrid cloud, multi-cloud (Azure, AWS, GCP) and datacentre environments (mainly Linux). A big part of the role is helping shape how network security is delivered globally as the business continues moving from traditional hosted infrastructure into cloud and SaaS platforms.
You will work closely with network, cloud and platform engineering teams to improve segmentation, secure connectivity and zero trust adoption across the wider estate. The role combines architecture, engineering and operational ownership, with responsibility for troubleshooting high-severity network security issues when required.
There are two huge projects that you'll be involved in:
- Palo Alto - global standardisation project
- Work with the newly created cloud team, who are architecting a Kubernetes multi-cloud environment. You will be the network authority here so experience of networking within public cloud environments will be really key for success here. Exposure to any AWS, Azure, or GCP will be OK.

- CISSP
- Experience within healthcare, finance or regulated sectors
- Public cloud migration experience
- Private cloud infrastructure exposure
- Automation or Infrastructure as Code exposure
Why Join
This is a genuinely large-scale environment where network security sits at the centre of platform engineering rather than being bolted on afterwards.
You will be joining during a major transformation programme as the business continues modernising its infrastructure and cloud estate globally. The work itself is complex, highly visible and tied to systems where uptime and security genuinely matter.
There is also plenty of scope to influence engineering standards and long-term architecture direction rather than simply maintaining legacy environments.
