Grad students and postdocs seem like a fairly untapped source for tech recruiting, especially outside of the CS department. Physics, neuroscience, econ, biology, and many other fields now involve lots of programming and data analysis, sometimes under demanding conditions (real-time or huge, noisy data sets). Many of the people are smart and highly-motivated, but making a tenth of the numbers you quoted (and with rubbish job security to boot). It should be like shooting fish in a barrel.
And yet.... they don't seem to be on many company's radars. I'm the only one in my group who is ever contacted by recruiters, and it's an undergrad CS degree.
Yes, you'll have to screen to figure who tweaks "the script that gives the numbers" and who's more like a developer. Recruiters might need to put in a little legwork to figure out how different kinds of researchers map onto open reqs. You might want to somehow prep non-traditional candidates for a developer interview, or figure out an on-boarding track. But you can afford a whole heck of a lot of that if a $250k/year job is sitting open.
