Almost every software development company and nearly every engineering team on the planet has some form of a technical lead. If you don't believe me, run a quick search on LinkedIn for "tech lead" and see how many hits you get.
At the time of writing in the United States, I got exactly 6,174 results matching that query. That does not account for hits from companies that aren't openly advertising the job as a leadership position or are calling it something else, such as "senior," "principal," etc.
In many cases, this role is often a place to which newer engineers can find themselves aspiring to attain, whether through a series of promotions or job changes. So, if this position is not only a very reasonable aspiration but is also in demand across the globe, then why interrupt your focus with retirement?
