(1) As an engineer, I prefer to be managed and guided by someone who actually knows what I work on, preferably better than I know it.
(2) A manager who actually understands the tech is often better at unblocking the team.
(3) Since senior IC openings tend to grow very thin as you become older, TLM path might be a viable career path for at least some.
Can this role work if we don't expect IC output from the TLM beyond what they themselves take on for their own satisfaction and growth?
