I am currently in the midst of job hunting as I am nearing the end of my tenure as a postdoc. I have recently come across an external job posting which greatly interests me, and have applied for the position through the online application process. During which, I was disappointed that there was no opportunity for inclusion of a cover letter explaining how my qualifications would make me a good fit for the position. The resume which was sent was not formatted to be a stand-alone document to highlight the relevant aspects of my research experience and I'm pessimistic that it will garner sufficient interest to merit a follow-up. There is also no method to update my user profile or uploaded resume! I do not know who the hiring manager is, nor do I have any contacts within this particular organization (Sandia National Lab @ Albuquerque, fyi). However, a bit of internet sleuthing turns up a likely candidate whom I am debating contacting. On the one hand, I don't want to be over-aggressive or annoying, while on the other hand I want to increase my chances of an interview. What would you advise me to do in such a position? If you think I should go forward with cold-contacting the potential(?) hiring manager, how do I ensure that the first-impression doesn't paint me as a nuisance? Thanks!
