• Develop functional requirements documents and procurement specifications for instrumentation and control components and integrated systems.
• Prepare and review design input documentation, including wiring schematics, cable block diagrams, loop sheets, I/O lists and mappings, and configuration documentation.
• Support the development and maintenance of Piping and Instrumentation Diagrams (P&IDs) and System Design Descriptions (SDDs).
• Interface with equipment vendors and suppliers; support preparation, review, and evaluation of technical specifications and procurement documentation.
• Produce clear, concise technical reports, engineering studies, and supporting documentation for internal and external stakeholders.
• Establish and enforce software configuration management practices for PLC and HMI software, scripts, and associated documentation, including version control and formal reviews.
• Review engineering drawings, calculations, and technical deliverables produced by other engineers for quality, accuracy, and compliance.
• Lead and support engineering process improvement initiatives through automation, engineering tools, and responsible application of advanced analytics or AI‑enabled methods.
• Utilize and oversee engineering automation tools such as Python, MATLAB, and advanced Excel to support calculations, design documentation, and data analysis.
• Mentor and support less experienced engineers and collaborate effectively with multidisciplinary engineering teams.
