• Generate precise Bills of Materials, including weld fittings, nozzles, manways, and structural components.
• Interpret and apply API 650/620/653, ASME Section VIII, UL-142, and UL-2085 standards in tank design.
• Utilize AWS D1.1 and related codes for welding details, symbols, and joint specifications.
• Revise drawings as needed to reflect internal review feedback, customer revisions, and contract changes.
• Collaborate with fabricators to resolve manufacturing queries and support production needs.
• Update drawings per as-built markups and maintain version control.
• Produce and organize drawing packages in PDF format for release.
• Simultaneously manage multiple projects in a fast-paced, production-driven environment.
• Visit the shop floor or fabrication yard to verify field fit-ups and gather design data when necessary.
• Respond promptly to production or QA issues related to design or documentation.

• Support the development of standard templates and design libraries for recurring tank types.
• Assist with implementation and maintenance of iLogic design rules to streamline future model generation.
• Participate in internal design reviews and cross-functional coordination meetings.
• Undertake other responsibilities as needed to support business objectives.

• Strict adherence to national codes, fabrication procedures, and client specifications.
• Demonstrate accuracy, clarity, and completeness in all design documentation.

• Ensure work meets internal QA standards and fabrication readiness.

• 5+ years of experience designing storage tanks (API, ASME, UL).
• Strong knowledge of AWS welding standards and interpretation of welding symbols.
• Proficient in Autodesk Inventor and AutoCAD for 3D modeling and 2D drafting.
• iLogic scripting or rule-based design automation is a plus.
• Familiarity with general construction and fabrication practices.
• Comfortable working under pressure and meeting tight project deadlines.

• Associate’s or Bachelor’s degree in Mechanical Design, Drafting Technology, or related field.
• Certification or training in tank design standards (API/ASME/UL) is a plus.
• Equivalent work experience in lieu of formal education will be considered.

• Reports to the Engineering or Detailing Manager.
• Works closely with Project Managers, QA/QC, Fabrication Supervisors, and Engineering staff.
