I was approached out of the blue on Linkedin by a recruiter hiring for a cyber/infrastructure role. The base pay was about 15k more than I make now plus a bonus of 30%. It would put me about 85k above what I make now.

I work remote currently so no commute. The base pay and bonus would be enough to cover a commute and put me over what I am making now.

Here is where it gets interesting and where I need the advice. They have NO active directory or ticketing system. They have about 450~ employees and a few hundred endpoints. They have ESXi for a hypervisor on Dell VX rail servers. A few linux servers run the ERP application and Synolgy NAS is used for Backup/storage. I get to pick new firewall/switches/APs/servers for infra upgrades and implement a migration to O365 for Defender, email, DLP, etc. Currtly they are using google workspace for email. I would be in charge of the migration from Google to O365. They also have no patching system in place other than general windows updates.

Network is cisco switches and a Palo firewall with some older Cisco APs. They currently have a 4ish member IT team with 2 juniors who handle helpdesk. I am being brought on to help modernize infrastructure and to implement some kind of cybersec/security compliance and standards. I get to build the solution and implement it along with a ticketing system and either on prem DC or Entra, while also implementing SCCM or Intune for windows patches and updates.

My background is networking, wireless, switching & routing, with sysadmin experience with ESXi, M365, server deployment and desktop support. I spent a few years in a service desk role and also in a sysadmin role. I currently work for an MSP doing mostly firewall installs.

During our discussions, the IT manager said that since he is busy and can't do things immediately there has developed a shadow IT situation where some departments are just doing things in a way they want without involving IT. 

My question, is this a bad idea? Leaving a remote role at an MSP with an increasing focus on KPIs or move over to this new and exciting adventure with a company with older gear that I get to help upgrade and be part of. I have only talked with the company briefly to get a feel for what the work  could entail.

One big thing worth mentioning is that this role was created after PE purchased the company but the company is still run locally.
