DCS (Distributed Control System) & Instrumentation Engineer - Yokogawa

OverviewThe DCS(Distributed Control System) & Instrumentation Engineer is essential to keeping the sewage treatment plant running safely reliably and efficiently. This role ensures that all automation control systems and instruments work correctlyprotecting people the environment and plant performance.What You Will DriveA DCS & Instrumentation Engineer with strong expertise in Yokogawa DCS (e.g. CENTUM/Prosafe) and SCADA systems for sewage treatment plant operations. The role involves endtoend responsibility for process control instrumentation asset reliability and industrial communications with a particular focus on maintaining the health and performance of Profibus (DP/PA) networks. The engineer must have experience working in corrosive H₂S-prone STP environments ensuring safety regulatory compliance continuous operations and overall optimization of plant performance.DCS / SCADA & Control SystemsAdminister operate and optimize Yokogawa DCS including control strategies graphics alarms trends historian tags and backup/restore.Maintain and enhance SCADA interfaces dashboards and reporting for O&M and compliance KPIs.Develop test and implement logic modifications (loop tuning interlocks permissives sequences) with strict MOC procedures.Manage alarm rationalization and limit settings to reduce nuisance alarms and improve operator effectiveness.Coordinate factory and site acceptance testing (FAT/SAT) for control system changes and expansions.InstrumentationOwn the lifecycle of field instruments including selection installation calibration loop checks diagnostics and replacement.Typical devices include DO pH/ORP turbidity/SS ammonium/nitrate chlorine flow (magnetic/ultrasonic) pressure level (radar/ultrasonic) vibration temperature and gas detection.Profibus DP/PA & Industrial CommunicationEnsure Profibus DP/PA network reliability including topology design segment diagnostics termination shielding/earthing redundancy spur lengths baud rates device addressing and GSD management.Use diagnostic tools (e.g. bus analyzers) to identify noise reflections voltage drops telegram errors and intermittent faults.Integrate field devices via Profibus PA couplers/links gateways and interfaces to Yokogawa DCS/SCADA; maintain device libraries.Collaborate with electrical and control teams for EMI mitigation proper cable routing and panel/earthing standards.Support interfaces with MCCs/VFDs PLC skids and plant SCADA/IMS/CMMS systems.Safety Compliance & CybersecurityEnsure all DCS/SIS activities comply with plant safety standards IEC standards and cybersecurity policies.Strengthen OT cybersecurity posture through access control reviews patch management and secure network segmentation.Develop a longterm DCS roadmap covering upgrades expansions and obsolescence risks (software and hardware).Qualifications :QualificationsYoure a Great Fit if You HaveBachelors degree in Instrumentation & Control Electrical Electronics or a related engineering discipline5-10 years of experience in process automation with strong handson expertise in Yokogawa DCS/SCADA within water wastewater or similar process plant environmentsProven experience in Profibus DP/PA commissioning troubleshooting and diagnosticsSolid background in instrumentation for STP processes including work in hazardous and corrosive environments (H₂S-prone areas)Familiarity with SIS/ESD systems (e.g. ProSafeRS) alarm management loop tuning and historian/reporting toolsExperience working with CMMS and IMS documentation systemsWhy Youll Enjoy Working with UsExciting ProjectsCareer GrowthDiverse TeamCompetitive BenefitsPositive Workplace CultureAdditional InformationSix Construct is guided by our core values of respect excellence co-creation passion and unity.
