There is ZERO career development in the Zillow IT org, most particularly in the Security space. The company claims to take security seriously, but doesn't anywhere anymore except on paper. The team has had massive turn over in the past six months. (Which isn't surprising if you consider the level of management turnover in the IT org as a whole.)
The annual review system is broken. You can get zero compensation raise and zero equity without an explanation as to why -even if you met ALL of your performance goals and have good manager and peer review. If you ask for some rationale as to how this happened with an entire year of good feedback from management the only response you'll get is, "Let's just focus on the future."
The annual review system seems to be based on how well your manager is liked by their manager. None of it makes any sense. So good luck getting a raise. Ever.
Honestly, if you are considering work on the security team at Zillow, you shouldn't. You can easily get hired elsewhere in town where the leadership takes security seriously. You can find somewhere where you won't have multiple managers in one year because of turnover. (literally) You can find a place that takes your career seriously.
The security team has seen high management turnover, zero career development, can't get traction with other teams, budget gets approved (verbally) then slashed over and over. Then upper management says asks why security hasn't solved for X problem. It's because we have no budget or headcount!
