• Assist with the preparation of professional bid packages and technical submissions
• Collaborate closely with designers and estimators to ensure all drawings reflect project requirements and quantities
• Contribute to the continuous improvement of CAD standards and workflows within the team

• Strong CAD skills (2D essential; 3D desirable), with the ability to produce clear, accurate layouts under time pressure
• Knowledge of building services, including mechanical, electrical, and sprinkler systems
• Sharp attention to detail with a
