best: work from home, above market salary for engineers, excellent laptop/equipment, good vacation policy, smart co-workers, flexible hours worst: no 401k match
I would not recommend the health insurance offerings. In my experience the carrier has a tendency to try and shift costs onto the policyholder by lowering the allowable charges once they've received a claim, though this could be an isolated situation on my part. Overall the benefit package seems to be aimed at being adequate enough for hiring coders. The company does a reasonably good job with flex time, which works well in their fully-remote environment. PTO is rather minimal (it's on par with my first job offer out of college), and even with working from home, you will eventually dream of being able to take more than one long vacation per year. Note that you will also want to be very proactive in ensuring that you receive all important benefits notifications.
