Pros

Great time off, schedule flexibility like 9/80, company shut down at end of year, caring coworkers, lots of resources, benefit add ons are great like pet insurance! They have a student loan company match program and tuition reimbursement. They seem to promote from within a lot too which is refreshing.

Cons

Spread out amongst lots of states East coast and West coast. Sometimes can make collaborating hard but the make it work well!

Pros

Great people. Good starting pay, bonus plan, 401k match. "Unlimited PTO", recommended target is 3-4 weeks and is highly encouraged (at least by my direct management and others). Many company holidays and a Christmas shutdown that makes taking 2 weeks off very easy (with some PTO days). Lots of interesting work and projects. Lots of opportunity to be part of different project phases and responsibilites.

Cons

Lean teams means you're likely juggling more than what's preferred/reasonable. Changing priorities can make closing out tasks difficult. Annual salary increases around 3-5% are reasonable but can be underwhelming given the amount of work and stress the job typically requires. Never recieved any market adjustment (while other local companies have), larger than expected salary increases, or anything that shows above average employee appreciation regarding pay.
