In a similar vein as the question How is a part-time degree (from a reputed institute) perceived in the academic job market?, what about holding a part time research job (Research Fellow)?
Currently, I work part time as a Research Fellow, part time High School Teacher, part time Programmer and part time Drone engineer - so, as a result, the amount of research output would be considerably lower than I would if full-time - a position I am aiming for in the near future. I already have a PhD.
In my CV, it will be very clear that this is a part time position, due to the overlap of my professions - this is different to the part-time degree scenario in the linked question, in that I am already in academia. How valuable is a part time research job with respect to joining full time academia (or industry)?
