HEAnet is Ireland’s National Research and Education Network, providing internet connectivity and ICT shared services across all levels of the Irish education system, reaching 1,000,000 end users. We connect learners and researchers across all of Ireland to education resources and to fellow national educational and research networks in Europe, and the rest of the world. We are looking for a Principal Engineer to join our Linux System Administrators on the Systems Team.


What the Systems Team does

The Systems Team drives the deployment and maintenance of HEAnet’s systems and services.


The Teams responsibilities fall into 3 streams.


Core infrastructure: This is a combination of virtual infrastructure, physical servers, and appliances, spread across our datacentres, and now an increasing foothold in containerisation and the Cloud. Essential for smooth operation is the automation and management of these resources.


Internal Services: All the pieces that go on behind the scenes to be able to deliver services, such as NTP, monitoring, logging, load balancers, database clusters, storage, authentication, as well as providing tools and services to other internal technical teams.


External Services: All the above help us to provide a diverse range of shared services to IT departments, educators, learners and researchers. Some of our more widely used services include, Identity and Access Management (Edugate), wifi roaming (eduroam), large file transfers, and video related services including video conferencing and live & on-demand streaming.

What you get from us

From the team

We value knowledge sharing and communication. We start each week with a team meeting to cover outstanding issues and planned work for the week, combined with team stand-ups each morning to make sure no one is hitting any roadblocks. You will also have a 1:1 meeting every two weeks with your manager. Every Friday we have presentations from anyone in the company on a wide range of topics from technical demos to project management to mental health. On different days of the week any team member may be working from home, so we use tools like Teams and video conferencing to keep in touch.


We encourage critical thinking and the exploration of new ideas. We often form cross-team special interest groups for specific topic discussions, both ongoing and for fixed projects. By design we encourage that the engineering standards that we set are influenced from the ground up, as the people working within the standards are the ones most informed. As Principal Engineer you will have the opportunity to influence and set strategy.


We provide a diverse workload. Everyone on the team has a core responsibility for a service or piece of infrastructure, but we limit individual performance objectives to a max of 30%, so you will get to work in multiple areas with different team members.


We promote a healthy work/life balance. Work outside of standard hours is rare and agreed in advance. We take the care of our team members' mental health seriously.
