The problem I see is that of being different from everyone else and the group dynamics associated with that. Also, this will lead towards you attempting to conform to the way the NFs are when you are not an NF, which would create some level of internal tension. I wonder about the issues and risks of being in a situation where you aren't able to be who you are. I'm sure you've considered these things.
The responses in this thread are excellent by the way.
To the OP: I am essentially in the inverse of your situation, in that I am a NF in an INTJ culture, and have been for like 10 years. There is much that I could say, and virtually none of it is positive. To be fair, I've been in physics-based research, which is not only INTJ but seems to draw the extra-cerebral extra not-social/friendly INTJ's. Have you ever seen the tv show The Big Bang Theory? Having spent a number of years in physics grad school, and having talked about it with some of my peers, that show is spot on in its portrayal of kinds of people that one often meets in physics. I also want to point out that I'm a NFP, INFP can often "hide" as INTP's, I've never worked in a NF culture [and so have something of a hard time imagining what they would actually be like], and other than yoga classes or spiritual groups I don't think I've ever been in a NF culture ever. In physics grad school, of all my peers, I think about 75% were INTJ's, and I've only ever had 2 NF peers, 1 ENFP and 1 INFJ.
Responding to the post I quoted above, I think it'd be fair easier thing to be a INTJ amongst NF than to be a NF amongst INTJ's. I personally think that NTJ's are the generally most judgemental and condescending of the MBTI types AND they aren't able to hide it or really keep it to themselves. NF's, and especially NFP's tend to leave others alone, let them be themselves, and don't generally try to condemn or "change" other people.
One of the major "failings" I've seen of NTJ"s towards NF's [ie me, the INFJ and ENFP weren't around anymore by this point] is what I refer to as "you can never succeed, the best you can ever do is to just not fail" mentality. Here are two examples. First, and I'm almost quoting word for word here from what they said: "In case you haven't noticed yet, we don't really believe in positive recognition here. You are expected to do your job, we won't praise you for that, well unless you do this just really super good job with some particular project. However, if your "failing or sucking" [note: that was my paraphrasing right there] we'll definitely let you know right away." Here is a second example, also largely quoted word for word: "I am very hard to impress. You are an average employee, and will be for about 5 years. If you work well, in 5 years might be an above average employee, if you work really hard you might be an above average employee in 4 years."
I would describe many of my current and past peers as: intense, serious, uptight, rigid, cold, emotionally retarded [they would probably say almost that themselves], emotionally oblivious [many have mentioned that themselves], unfun, not cool, uber uncool, and maybe assholes.
Beware of the idea that information is "value free" and hence can be discussed freely whenever. For example, asking what a coworker thinks of someone and then saying that in public, or publicly calling your bosses bosses boss an idiot and then spending 5 minutes going in detail about why you think that.
It might be hard to do, but be very cognizant of being or appearing condescending in what you say or how you say it.
I'm amazed how many people I've met, usually PhD level, who never say something like "Morning Joe" or "Morning" or "Good morning Joe" or "How's it going today Joe" but instead just seem to glare at you, and in an ?accusing?/declarative voice just say "Joe." Be polite, or if were gonna talk lets talk, but don't just "acknowledge" me while glaring at me [or in this example, Joe] and walk by.
I don't really have any advice here, but I'd be cognizant of the possibility of being seen as rigid, or frigid, emotionally speaking.
I think its a J, IJ, TJ, and ITJ thing to look and feel like you *know* you are right. Even if your not. Be especially aware of this if what your doing is seen as "invalidating" "denying" or "calling incorrect/irrational" other people's emotions and emotional reaction. I think this may very well be the biggest issue of NF's with NTJ's. The whole "efficiency above all else, respect my competence, don't infringe on my independence" may all be pretty up there. I remember offering an INTJ help on one particular occasion, and there reaction seemed to scream "I am competent enough to do this by msyelf, don't insult my competence!" coupled with "don't insult my independence by implying that having someone else helping would be a help to me!"
Many INTJ's Ive met, *especially* INTJ women seem incredibly pushy, bossy, and sometimes just outright bitchy. I've heard a number of NTJ peers say exactly this INTJ women as well. Personally, I think this gets most magnified when said INTJ woman seem to think that they can do everything just fine by themselves and don't need nay help or anyone else around.
Efficiency is not the number 1 most important work attribute, not is your independence guaranteed. Especially when an INTJ "blows over" someone else's feelings in the name of expediency or efficiency.
Be comfortable with other people sharing their feelings with you, and occasionally needing emotional support or consolation.
General discussions about "everyone is so stupid!","humanity is composed of nothing but idiots" "why don't other people see/recognize/appreciate my greatness" "why most of the population should be forcefully sterilized" "if you were smarter you'd understand my ideas and why there so great, but your just a an average stupid peon and it would be a waste of my time to dumb down and explain my ideas so that your puny little mind can understand them" and other such demeaning things should be kept to yourself.
I'm sure there are many things I've forgotten, but thats a start.
Again, I've never worked in, and have barely even ever been in a NF environment, so I can only guess what that would be like. I feel liek much of what I've said is stuff to avoid, and not "stuff to make sure you do." I'm curious, what kind of work will this be that is mostly NF??? Psychology prof, psychotherapist??? Also,a re you willing to say anymore about where in the Southwest you are???
Oh, I think the other posts here have had lots of good advice, particularly Satine's.
