A degree in the life sciences prepares one for numerous non-academic careers. Still, many start their scientific careers hoping to follow the traditional academic route (find tips for getting a faculty position here). Possible roadblocks only become obvious at rather late stages (i.e. postdoc level) and can include the pressure to publish in high-impact journals, and the requirement for a high grant success rate. At this point, candidates are highly experienced but often have to start pursuing other options.
While some non-academic career options require additional study for late career scientists to become more appealing on the job market (e.g. a postgraduate degree in law, an MBA, or similar), there are many roles out there that require exactly what life science PhDs can offer: vast practical lab expertise, experience in different scientific fields, and knowledge of how to troubleshoot problems at the bench. Specifically, roles in technical support make excellent use of the skills developed by life science PhDs.
