Principal .NET/AWS Engineer

Location: Seattle, WA or Minneapolis, MN or Atlanta, GA or Dallas, TX or Miramar, FL

Pre-screening Question: If you were to build a new set of APIs/services and you were not going to use .Net, what tech stack and language would you choose? And Why?

This person will be the Lead and Own the technology and have a supporting team of three other engineers. The caveat is that the goal would be to eventually retire the .Net codebase and replace it with a modern cloud solution (in AWS not .Net) - this person may lead the migration to the cloud of the current solution ) and potentially the design and architecture of a brand-new in AWS
