What do you all consider to be the best companies to work for to truly develop skills as and gain quality experience as an engineer. I'm currently a backend enginner with ~3 years experience in technologies including: Ruby on Rails, Elixir / Phoenix, PostgreSQL, Redis, various AWS services, and RabbitMQ. Compensation is certainly an important aspect of a future role, but I feel that focusing on developing my skillset is higher priority at this stage. Some companies I have in mind are: Airbnb, Uber, Lyft, Dropbox, Palantir, Block, and Stripe. I'm based on the East Coast of the US.
