Pros
Working at Planet Labs will give you the chance to create the future of an industry as well as making positive contributions to the world! The motivating mission and philosophy behind this company was enough for me but the added plus has turned out to be the people and the culture they create. If you enjoy working hard and with a purpose, while having a good time doing it then this is the right place for you. I am a recent hire ( a few weeks ) and already feel like a part of the family. I have the opportunity to interact with the the smartest people in engineering, aerospace, finance, open data, etc. and find it a dream to work hard and contribute to the goals of this company. Although the organization structure is technically hierarchical for various reasons you will feel as if the organization is flat and you can approach anyone, including executives for anything. If you want to make a difference, have fun doing it and make some friends this is the place for you!
Cons
I wish I would've landed this job earlier :)
