Groupon

Groupon has a pretty good hiring standard, which means you are mostly surrounded with talented professionals and excellent products. The principal engineers are pretty solid, and the overall architecture of Groupon's systems is done pretty well.

There is a good variety in the technology stack that different services in Groupon manage. At the same time, systems are quite open, and developers are directly responsible for the production infrastructure. Hence, it is always a good place to learn and grow.

Internal mobility allowed me to target technologies I wanted to learn.

Work-life balance is also pretty good. There are lots of perks, employee satisfaction initiatives, and modes for appreciation. Overall, a nice place to work at.

It is a small office. As Groupon is growing, a bigger office might be desired.
