Can I move from Customer Success/Experience role to Product Manager? If yes, how should I prepare myself for it? What certifications should I get? Are fully remote opportunities available for the product manager role?
While obtaining a relevant certification does not hurt, being able to speak to hands-on functional experience will be more interesting, to internal and external interviewers. To that end, I would start by exploring internal opportunities:
Are there open Product Management roles in your company that you can network toward? Internal Product Management teams be open to helping you ramp up in a new function, valuing that you already know how the company works. I would suggest highlighting your frontline customer exposure and any poignant VOC that demonstrates your deep understanding of customer needs.
Alternately, you might consider pursuing Product Management-type work in your current Customer Success organization. This could include Product Managing internal tools, helping set internal/team strategic goals, and reporting out on customer impact.
