Earlier quoted context omitted.
I think you're not doing the math on the stock (which is currently over $550). e.g. $73k base + $21k bonus + $57k stock = $151k for an engineer in their second year (no info about previous experience). Absent a lot of other context it does sound fair to me, or at least not "shockingly low".
I value those things differently, because the bonus is only for the first two years, and the stock is a one-time grant. Just like there's 'no replacement for displacement' in engines, there's no replacement for base salary in compensation. What I'm seeing in that compensation package is no incentive whatsoever to stay after you finish your second year, and no real incentives to start in the first place. $150k in Seat…
RSUs are frequently given during annual performance reviews to employees with good reviews. For my first annual review I received a score of "Exceeds" which is second from the highest. For that, I got 35 RSUs worth roughly $19K when they vest (at current price).
In theory, good employees will continue to receive stock grants that vest over time, thus creating incentives to both stay and to perform well.
