  Prototyping for smart charging - for electric vehicle. Some coding is required; they have others on the team that can do the coding. They are writing the code - the prototype - they need some to write better quality code **The architect defines the code quality and is "laying foundation**Have to have architect enterprise experience **Typically this type of person is a consultant** they would have worked with other various organizations with broad experience across multiple industries. Look at different architectures to see what they are doing. They also have to have started as a coder. Get data from the cloud, communicate with the users Set parameters on charging, what is needed and how it is accomplished
  
  Agile prototype AWS Cloud simulation needed C++, Python, these are needed Automotive is not needed Prototyping tools - Prefer HTTP Good full stack Architect - will chat with them
  
  Working on the charging station there - that's why there is a need to be local. Auto experience is not required
