Being 45 and just been served redundancy notice yesterday
I can appreciate. 4 years ago I was in the same boat. Then my CV is peppered with technical ideas - drones, image processing and quantum computing (although I did manage the last one as part of a company hackathon
).
Back then - I switched from technical side of product management to P&L product management, however after a year the CEO got the boot and everyone was made redundant as they refocused on their core company strength and not building into a new business. Leaving me with a 1 year P&L and every other job being seen as "technical" (being accountable for presales, product to operation) by recruiters that do not understand.
I took a "step down" back to technical with a larger organisation (230,000+ people) specifically for experience in the larger organisation. The role I'm in now I'm technically accountable for our 90+ people (across many disciplines including project managers, business analysts etc). My day typically revolves around financial and optimising things to make the team more successful. I am the go-to person to solve the impossible (just part of the job rather than a brag).
When I apply for the next role I can no longer apply for "technical" roles. It's more management, possibly CIO/CTO. I like product management.. but I like owning the product if I'm going to obsess about it, the customers and the people in the team. We have a senior product manager and she freely admits I can do her role too however that's not what the recruiters will see based on my "technical" job title.
So what was the purpose of that ... You're focusing on what you aren't.
You have;
* experience
* you are someone that people come to when they have nowhere else to go to solve the issue.
* I suspect that you're naturally steady given a changing environment and able to cope with that.
* Adding an self-study for project management would indicate that you're serious and you can sell that as a team management and delivery. It would demonstrate that you can plan, execute and deliver - it's also something that recruiters "understand".
I would - define a direction, ignore the past and start building towards that.
