• Provide technical guidance and quality control review for junior designers and drafters
• Interface with project engineers, project managers, and municipal clients to support project delivery
• Assist with constructability reviews, quantity takeoffs, estimates, and preparation of technical documents
• Maintain CAD standards, file organization, and data integrity throughout the project lifecycle

• 8-10+ years of total related experience, with 5-7 years of design experience is strongly preferred
