Primary Function

Under general supervision and technical mentorship, the CAD Production Technician III performs intermediate to advanced CAD production work supporting water and wastewater infrastructure projects, including pipeline conveyance systems and treatment facilities. This role applies established drafting standards and procedures to develop accurate, constructible engineering drawings using Civil 3D and/or Mechanical CAD platforms, with increasing independence and technical responsibility. Assignments are intended to expand exposure to complex pipeline layouts, plant infrastructure, and multi-discipline coordination, building upon prior CAD experience while further developing job knowledge and technical skills.

• Perform a variety of intermediate to advanced CAD production tasks with increasing independence, exercising sound judgment to adapt processes, resolve technical issues, and recognize when engineering input is required
• Prepare and revise pipeline and facility drawings from redlines, sketches, and design markups, including:
• Waterlines, sanitary sewer, and force mains
• Pipe profiles, plan-and-profile sheets, and details
• Treatment plant site plans, piping layouts, and mechanical arrangements
• Utilize Civil 3D for pipeline alignments, profiles, pipe networks, surfaces, and data references, and/or Mechanical CAD tools for plant piping, equipment layouts, and details
• Maintain CAD data integrity and drawing standards throughout the project lifecycle
• Coordinate drawings across disciplines, supporting consistency between civil, structural, mechanical, and process elements
• Reference and apply information from vendor drawings, equipment cut sheets, catalogs, and technical manuals, interfacing with engineers and designers as needed
• Support construction-phase activities, including drawing revisions, clarifications, and record drawings (as-builts)
• Assist with field assignments as required, such as site visits, data verification, or construction coordination
• Share technical knowledge and collaborate across project teams, providing informal guidance or mentoring to less experienced production staff
• Demonstrate accountability, initiative, and reliability in managing workload with minimal supervision and supporting overall team objectives

• Strong knowledge of intermediate to advanced CAD drafting practices, standards, and workflows related to water and wastewater projects
• Proficiency with Civil 3D for pipeline and conveyance design and/or Mechanical CAD platforms for treatment plant piping and equipment layouts
• Ability to prepare and edit complex engineering drawings, ensuring accuracy, constructability, and data consistency
• Understanding of pipeline and treatment facility components, including piping systems, appurtenances, and site constraints
• Ability to work independently on technical tasks, provide peer mentorship, and interface effectively with engineers, designers, and technical staff
• Capability to research and apply information from technical references and vendor documentation with minimal oversight
• Strong organizational skills with the ability to manage priorities, adapt to changing project needs, and maintain quality standards

• High school diploma or equivalent required;
  Associate’s degree or Technical Certificate in Drafting, CAD, or related field preferred
• 4–6 years of related CAD/production experience,…
