  • 2 years of experience in software development or other IT technology R&D capacity
  • Experience in SR&ED or other R&D related government tax incentive programs is an asset
  • High comfort level and knowledge of computer software/IT technology topics and related terminology
  • Ability to conduct conversations to understand root causes for issues and grasp key development concepts in R&D scope
