  • Experience balancing client expectations against technical requirements (and been able to explain this clearly internally)

We’d love it if you…

  • Had survived a production outage (even better if service continued)
  • Know everything there is to know about a topic/framework/tool of your choice
  • Have used or been exposed to more than one framework and understand why you would use one of another
  • Understood page performance and how to reduce load times across the stack
  • Had a sound knowledge of common security risks and how to protect against them
