  • Understanding of version control systems (such as git) 
  • Experience working with the open-source community 
  • Experience working with lab equipment to debug embedded systems 
  • Familiarity with DevOps principles, practices, and tooling 
  • Familiarity with silicon design and verification methods, and the usage of silicon design tools
