I have been offered a post-doc position at a site that participates in the uniform notification process and must give the site an answer tomorrow. This is my only offer at the moment, but there are other sites of more interest to me that don't participate in the uniform notification date (i.e., application deadlines haven't even passed yet). I plan to accept the current offer, but was wondering if anyone has any advice on how to navigate this process, especially because I would consider backing out at a later point if a more preferable site gives me an offer. Although I come from a fully funded Ph.D. program, I am not concerned about burning bridges with "big names," as I am geographically restricted for the post-doc process anyway and I am not in a super specific subfield. I am more concerned with seeming inconsiderate and potentially leaving this site out to dry. Thoughts?
