What you get from us 

From the team 

We value knowledge sharing and communication. We start each day with a SCRUM to cover outstanding issues and planned work for the day, combined with fortnightly team stand-ups to make sure no one is hitting any roadblocks and to identify progression or delays in any of the major company projects HEAnet is involved in. You will also have a 1:1 meeting every two weeks with your manager or as required.  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.  


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.
