In every tech organization, there are some people that seem to know every system, everybody, and every problem. They're super helpful, and save coworkers months of wasted efforts, by short-circuiting dead end paths, sharing efficient workflows, knowing which services already exist, and generally having great technical judgement. *None of those skills are quantifiable on performance reviews, other than peers saying thanks (if they're lucky). *Many underrepresented engineers fill these roles.
