Job Brief: We are seeking an experienced and detail-oriented Senior Design Engineer (Instrumentation & Control) to lead the design and development of instrumentation and control systems for water and wastewater treatment projects. The role involves designing control system architecture, developing I&C documentation, and supporting the programming and integration of PLC/HMI/SCADA systems. The ideal candidate will have a strong background in process automation, instrumentation, and control design within the industrial or water sector.

• Lead the design and development of I&C systems for water treatment plants, ensuring compliance with technical specifications, client standards, and regulatory requirements.
• Prepare detailed engineering documentation
  , including Instrument Index, I/O Lists, Control Philosophy, P&IDs, Logic Diagrams, Loop Diagrams, and Control Panel GA drawings.
• Define control system architecture
  , including PLCs, HMIs, SCADA systems, and network communication protocols.
• Develop functional design specifications (FDS) for automation systems and coordinate software development with the programming team.
• Select, specify, and validate field instruments such as transmitters, flowmeters, analyzers, pressure sensors, and control valves based on process requirements.
• Review and approve vendor documents and ensure all instrumentation and control system components align with project standards.
• Coordinate FAT (Factory Acceptance Test) and SAT (Site Acceptance Test) activities related to I&C systems and ensure documentation accuracy.
• Collaborate with process, mechanical, and electrical teams to ensure full system integration and functionality.
• Provide technical support during commissioning phases, ensuring seamless integration between electrical and automation systems.
