There are some well-known universities, which I considered applying for several positions at each school (as a recent Ph.D. graduate). The potential problem is that, at each school, some of the positions of my interest are true research positions (either postdoctoral, or research associate), but some are staff positions, despite being closely related to teaching and/or research, i.e., teaching and research assistant (or manager) for education technology platforms (course development), graduate program institutional research (which includes data analysis) and some others.
While I certainly would strongly prefer a true research position, today's tight competitive environment forces me to approach the situation pragmatically, rather than with cautious optimism (my circumstances additionally push me in that direction - I don't have time to apply first to research ones and wait for response, before applying to the staff ones). Therefore, I am thinking about applying to all positions that I see fit, regardless of whether they are true research of staff ones.
1) are there any significant reasons against applying to both types of positions simultaneously;
2) will simultaneous applications hurt my chances to be hired on pure research positions?
