Pros
Flexible Hours - I can start my day when ever I want. Lots of opportunities to add projects outside of my usually scope of work. I have an awesome manager who tells (and shows!) me regularly that I am valued. I work with great people! There is a culture of wanting to achieve great things. I love working with others who also take pride in what they do and care about our customers. The South Lake Union area is really pretty, I like being close to the city. I get to travel for work! I have been to Europe three times since I started.
Cons
Commuting into Seattle isn't great and it can be difficult to find parking that is reasonably affordable. If there are people on your team that aren't performing well, it is difficult to get them off of your team.
