  • Ensure design solutions comply with applicable codes, ADA requirements, and firm standards
  • Support client meetings and assist with presenting design solutions
  • Manage multiple tasks and deadlines while maintaining accuracy and quality
  • Mentor and support junior designers as appropriate
