You might be able to handle the technical work, but one of the semi-open secrets in technology is that 90% of problems, once you peel them back far enough, are people problems disguised as technical problems. To prepare yourself for those, assuming you're a "learn by reading" type, I recommend reading just about anything by Jerry Weinberg. The Psychology of Computer Programming is a classic. I was fortunate to discover this early in my career. Becoming a Technical Leader is another good "big picture" book, with solid tactical advice for advancing in a technical career. Read either or both of these, and you'll steer clear of a number of common early-career mistakes.
