CAD Draftsman

Provide high-quality drafting and document control support to ensure accurate, up-to-date engineering drawings and Process Safety Information (PSI) that enable safe, reliable, and efficient plant operation and project execution.

Accountability 1: Safety, Health & Environmental (SHE)

• Comply with and actively promote the INEOS Life Saving Rules, the INEOS 20 Principles of Process and Behavioral Safety, and all site SHE requirements.
• Maintain and update plant PSI drawings (P&IDs, plot plans, isometrics, electrical drawings, and associated documentation) to ensure accuracy and compliance with INEOS standards.
• Ensure all drawing updates are completed in response to Management of Change (MOC), capital projects, and maintenance activities, maintaining alignment between field conditions and documented design.
• Assist in audits, PHA/HAZOP reviews, and incident investigations by providing accurate and current drawing packages.
• Identify discrepancies between field conditions and drawings and escalate issues that may impact safe operating envelopes or regulatory compliance.

Accountability 2: CAD Drafting & Drawing Management

• Prepare and revise a wide range of engineering drawings including P&IDs, PFDs, general arrangements, piping isometrics, electrical/instrument layouts, and plot plans based on engineer markups and redlines.
• Convert field redlines and engineering concepts into accurate, constructible CAD deliverables that meet company and industry drafting standards.
• Ensure consistency with ANSI/ISO/ASME and company drafting standards, including layering, symbology, and revision control.
• Generate and maintain as-built drawings to reflect actual installed conditions following project completion or field modifications.
• Support development of design packages for construction, including drawing sets, document indexing, and revision tracking.
• Manage drawing numbering, version control, and archival in company systems to ensure traceability and audit readiness.
• Support engineers and designers with data extraction, drawing updates, and document formatting to meet project and maintenance needs.

Accountability 3: Field Verification & Asset Accuracy

• Perform field walkdowns to verify existing conditions, equipment locations, and routing details.
• Capture and document discrepancies between existing drawings and physical installations.
• Collaborate with Operations and Maintenance to validate system configurations and ensure drawings reflect practical operating conditions.

Accountability 4: Project & Maintenance Support

• Provide drafting support across all project phases including FEED, detailed design, construction, and commissioning.
• Assist rapid-turnaround work for plant issues, ensuring timely updates to drawings supporting maintenance execution.
• Coordinate with engineers and designers to ensure drawing deliverables meet schedule, scope, and quality expectations.
• Review vendor drawings for integration into plant records and ensure alignment with site standards.
• Support preparation of documentation for permits, excavation packages, and work packs.

Accountability 5: Continuous Improvement & Digitalization

• Contribute to improvements in drawing standards, workflows, and document management processes.
• Support initiatives to digitize and standardize legacy drawings and records.
• Identify opportunities to improve drafting efficiency using available CAD tools, templates, and libraries.
• Participate in knowledge sharing to improve drawing quality and consistency across disciplines.
