DCS (Distributed Control System) & Instrumentation Engineer - ABB

OverviewWhy This Role MattersThe DCS(Distributed Control System)& Instrumentation Engineer plays a critical role in ensuring the safe reliable and efficient operation of the sewage treatment plant. This position supports the heart of the plants automation and control processes directly impacting performance compliance and operational stability.What You Will DriveA DCS & Instrumentation Engineer with a strong background in ABB DCS (e.g. ABB 800xA Freelance) and SCADA systems for sewage treatment plant (STP) operations. The role involves end-to-end responsibility for process control instrumentation asset reliability and industrial communications with a particular focus on maintaining the health of Profibus (DP/PA) networks. The engineer must have experience working in corrosive H₂S-prone STP environments ensuring safety compliance continuous operations and optimized plant performance.DCS / SCADA & Control SystemsAdminister operate and optimize ABB 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) under 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 instruments.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 ABB DCS/SCADA; maintain and update device libraries.Collaborate with electrical and control teams on EMI mitigation 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 requirements and cybersecurity policies.Strengthen OT cybersecurity through access control reviews patch management and secure network segmentation.Develop a long-term DCS roadmap covering upgrades expansions and software/hardware obsolescence.QualificationsYoure a Great Fit if You HaveBachelors degree in Instrumentation & Control Electrical Electronics or a related engineering field510 years of experience in process automation with strong handson expertise in ABB DCS/SCADA systems within water wastewater or similar processplant environmentsProven experience in Profibus DP/PA commissioning troubleshooting and advanced diagnosticsSolid background in instrumentation for STP processes including work in hazardous and corrosive (H₂Sprone) environmentsFamiliarity with SIS/ESD systems (e.g. ProSafeRS) alarm management practices loop tuning and historian/reporting toolsExperience working with CMMS platforms and IMS documentation requirementsWhy 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.
