• Develop wiring diagrams, loop diagrams, and interconnection drawings
• Coordinate the development of Piping and Instrumentation Diagrams (P&IDs) with process and mechanical engineering teams
• Perform instrumentation engineering calculations and sizing, including control valves, flow measurement devices, and thermowells
• Apply knowledge of measurement technologies and control strategies to select instrumentation for pressure, temperature, flow, level, and analytical measurements
• Participate in process safety activities, including HAZOP studies and design reviews, and incorporate findings into control system design
• Support procurement activities, including technical specifications, RFQ documentation, bid evaluations, and vendor submittal review
• Coordinate with control system vendors and suppliers, including participation in Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT)
• Provide technical support during construction, installation, and commissioning, including field inspections and issue resolution
