  • You have experience or want to work with Linux, Docker, private/public cloud
  • You love freedom and don’t like being micromanaged. Given context, you're capable of self-direction
  • You are a sharp communicator who can explain sophisticated data problems in clear and concise language
  • You are motivated to explore new technologies and learn and can do so without taking formal education
  • You are eager to share your own ideas, and willingness to those of others

  • Access to tools and resources to do your job (IDEs, Safari Online subscription, conferences and meetups, all the coffee and soda you can drink, and much more)
