- KOLs in that specific medical field are invited to be board members mainly working to steer the product towards market fit. And provide insight into what will work or not in 'the real-world'.
- MD's working as Clinical Advisors in 'research boards' they would come in every 2 weeks and join R&D/Product brainstorming sessions or demo days and provide feedback, suggestions, insights.
- MDs actively working as clinical researchers designing and coordinating clinical trials
- (less common) But a few people in my professional network are full time C level execs that have a Medical background (CTO/COO/CEOs) but they are all in more bio-tec/materials fields and most actually started the companies they are in.
The takeaway is tech companies usually struggle with access to clinical research, and have knowledge gaps about hospital workflow, procedures, surgical sub-steps etc. In both of those areas clinical staff is always needed.
I think another big part of the answer is that it will depend a lot on what medical specialty you choose in your medical career. Some fields are much more active then others in terms medical tech. (Cardio, Neuro, Pneumo, ENT, Sleep, Ortho, Endocrin) Hope it helps.
