Haha, it typically takes 6 months to get up to speed at a company as everyone has their own set of unique tools and infrastructure. Also at that cadence you are not vesting any stock(1 year cliff?) so that seems very strange. Having worked with high-vis engineers in the past, alot of them seem to be vanity hires, they really don't impact much change and probably stoke the egos of the upper managers/execs much like (prof. slughorn from harry potter), collecting "geniuses".
