you can learn from your sub con

i was in project engineering for 5 years before jump to sales

i would say you could always learn technical knowledge no matter what is your job scope

just get to know your client, manage them well, then hopefully one day you can goyang kaki jadi end user. haha

if not just continue on learning from all sides.

you are still early in your career and still got time to change to technical post.

but the opportunity is limited, that is why many stuck in sales.
