DCS (Distributed Control System) & Instrumentation Engineer - ABB

Overview

Job Description

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
