I had a conversation with some researchers at a major biology/genomics research lab in Maine last week and they pushed back hard when I asked if they were mainly looking to hire PhD candidates. Apparently it's a real problem that grad students and postdocs come onto their projects for just a couple of years and then move on, leading to frankenstein code and unfinished projects that no one can easily pick up and continue. They claim that they would very much like to hire developers who wanted to work long-term on bioinformatics software not just as a means to a PhD.
