  • Support other departments and guide CAD operators to ensure delivery of high-quality outputs.
  • Perform QA/QC activities on own and peers designs to detect, analyze, and eliminate discrepancies, while positively accepting feedback and applying lessons learned to continuously improve skills and prevent recurring mistakes.
