Pros
They do a great job of building a team of good people that are outgoing and entertaining. They provide some nice perks like employee discounts, free lunches and free money to spend on their platform. Hours are very flexible so long as you put in your 8 hours. The codebase is actually surprisingly good with the exception of the admin section which is over a decade old. The VP of product is an awesome guy.
Cons
The release process is an absolute mess. Going from code-complete to release can take a month or more as your project gets added to a massive queue of projects going into one massive release. Once the release process begins you can expect the undermanned QA team to blame you for random issues from one of the 50 other tickets in the release. The poor QA team is there past 8pm multiple times per week and if one of your tickets is stuck in that release you can expect the same. Although the hours are flexible you had better not go in early since you'll be staying late either way. The worst part of the terrible release process is that your old tickets come back to bite you when you're working on your new ones so you'll feel punished for working hard and getting ahead. Then if anything tangentially related to your feature has an even slight hiccup you'll be to blame as well. You'll also be expected to go on a regular support rotation that includes nights and weekends since those are peak ordering hours. The system includes a web API, iOS, Android, Third Party Apps, Third Party Integrations, automated calling, emails, faxes and SMS messages so there are 80 million points of failure you'll be expected to handle in your free time. Its not worth getting to know people on the team and building relationships since the turnover is so high. In my time at delivery.com I saw every single developer that had been there longer than me except for H1-B visas leave the company. The pay is non-competitive and it would be even if the work didn't include the extended hours. Look elsewhere.
