What information would you expect when starting a new network admin role?

I’m a network engineer working for a University with around 50 MPLS sites. We have four main campuses with many other minor sites. We have five team members across two geographical locations around three hours drive apart. The team consists of an architect, two senior engineers and two standard engineers. A new person is starting in our team next month (replacing a standard engineer) who will be based at the other geographical location. I’d like your advice and opinions on what I can do to prepare for this new person starting.

Our environment is complex and due to the small size of our team versus the workload, there’s not a lot of documentation of our systems. I want to develop an on boarding process (or something? ANYTHING?) for new members of our team but don’t know where to start.

What have your good/bad experiences been when starting with a new organisation? What things did you initially learn that helped you in your new role? What important things got left out?

My role is mainly based around maintaining/upgrading L2, responding to level three tickets and managing the wireless infrastructure. The new person will have similar duties but in a region with a majority EOS L2 fleet. They have a good background in network support in a small-mid sized environment, but likely with different brands and network designs.

Let me know what your experience has been starting in a networks team and what you wished they’d done for you.
