Description

Company Description Six Construct, a subsidiary of the BESIX Group, is the largest Belgian construction company operating in the Middle East. The company combines the efforts of a highly skilled workforce, along with strategic planning and innovative use of technology to overcome the most complex business challenges. Six Construct is a multi-services company that operates in the construction of commercial and residential buildings, sport and leisure facilities, infrastructure and marine-related projects. The company currently employs a workforce of approximately 4,000 in the Middle East, and a total of 10,000 worldwide. Job Description Why This Role Matters? The 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 plant’s automation and control processes, directly impacting performance, compliance, and operational stability. What You Will Drive A 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 Systems Administer, 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. Instrumentation Own 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 Communication Ensure 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 & Cybersecurity Ensure 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. Qualifications You're a Great Fit if You Have Bachelor’s degree in Instrumentation & Control, Electrical, Electronics, or a related engineering field 5–10 years of experience in process automation, with strong hands‑on expertise in ABB DCS/SCADA systems within water, wastewater, or similar process‑plant environments Proven experience in Profibus DP/PA commissioning, troubleshooting, and advanced diagnostics Solid background in instrumentation for STP processes, including work in hazardous and corrosive (H₂S‑prone) environments Familiarity with SIS/ESD systems (e.g., ProSafe‑RS), alarm management practices, loop tuning, and historian/reporting tools Experience working with CMMS platforms and IMS documentation requirements Why You’ll Enjoy Working with Us Exciting Projects Career Growth Diverse Team Competitive Benefits Positive Workplace Culture Additional Information Six Construct is guided by our core values of respect, excellence, co-creation, passion, and unity.
