Hey Guys,
So, I work for a Municipality (large city) and currently work on the infrastructure team. But we have dept's that have their own IT team, independent of us. They manage their own servers. So i applied to one of these depts, and the hiring manager and me clicked. The hiring manager told me they would have a decision within a week, but I haven't heard back (it's been 3 weeks since I interviewed). I know they haven't hired anyone, because I manage the city's Exchange environment

. I emailed HR (a week ago) and have not received a reply.
I know the hiring manager's email. Should I email him directly, since I received no reply? Because I have a job offer from another company. But I would love this job, because I would be the lead engineer, have 2 people I manage, and I will be responsible for migrating from Hyper V to VMware and also design their wireless network. Basically my dream job, because I am trying to specialize in virtualization. In the other job, I would be the JOAT at a 200 user company, but not get to touch the virtual environment or get major project work.
Also, If I decide to email him, how should I write the email?
Maybe:
Hey IT Manager,
I emailed Hr and got no reply, so I'm emailing you. Do you guys still want me? I have an offer on the table, but this is my dream job, please hire me?
Cliffs:
OP applied to a dream job within same company, got great vibes.
OP got job letter from different company.
OP wants dream job, HR not responding.
OP wants to email hiring manager and tell him he has job offer, OP would like TechExams community to help with said email.
Excuse the grammar errors.
Thanks in advance.
