OT Systems Engineer - Control Systems & Field Integration

sibilities**
Control Systems & Field Integration

• Engineer, program, and maintain SCADA/DCS/PLC for mining processes (drill/blast, dewatering, crushers, conveyors, mills, flotation, thickeners, tailings, hoists, ventilation, fuel/lube skids).
• Integrate and commission field devices: flow/pressure/level/temperature transmitters, belt scales, weighbridges, vibration/temperature sensors, gas detection (CH₄, CO, NOx), proximity/CAS, machine health, and RTUs.
• Develop control narratives, cause & effect (C&E), P&IDs, loop tuning, and FAT/SAT/IOQ plans; execute commissioning and handover to operations.

Mining Systems Integration (Pit-Plant-Port)

• Integrate Fleet Management Systems (FMS) and high‑precision guidance with plant and business systems (e.g., dispatch, grade control, short‑interval control, LIMS, ERP/MES).

• Implement conveyor & stockpile automation (interlocks, anti‑rollback, emergency stops, soft‑start/VFD, re‑start sequencing, blocked chute/belt drift).

• Enable Hoist & Winder controls (redundant safety chains, overspeed/overtravel protection, SIL-rated logic) and Ventilation‑on‑Demand (VoD) schemes linked to tracking/gas data.

OT/IT Convergence & Data

• Architect data flows to historians (e.g., PI/AVEVA), MES, analytics, and cloud/edge platforms; standardize tags, namespaces, and asset models.
• Implement OPC UA / MQTT (Sparkplug B) gateways; rationalize Modbus/EtherNet‑IP/PROFINET/Profibus/CAN.
• Build operator dashboards and production KPIs (availability, OEE, tonnage, energy per tonne, recovery).

Cybersecurity & Safety

• Apply IEC 62443/ISA‑99 for segmentation, asset inventory, hardening, patching, backups, and incident response in OT.
• Engineer to IEC 61511/61508 / ISO 13849 for functional safety; specify SIL requirements and manage verification/validation.
• Ensure compliance with applicable mining safety regulations (e.g., MSHA/DGMS/DMRE/WorkSafe) and hazardous area practices (e.g., IEC 60079; intrinsically safe equipment in gassy mines).

Networks & Communications (Harsh Environments)

• Design and support industrial networks (Layer‑2/3 switching, VLANs, redundant rings, PTP/NTP time sync).
• Deploy and maintain underground leaky feeder, private LTE/5G, industrial Wi‑Fi/mesh, microwave, fiber, and field‑bus; plan coverage, roaming, and QoS for mobile assets.

Reliability, Maintenance & Analytics

• Implement condition monitoring (vibration, thermography, oil analysis) and integrate with CMMS/EAM for predictive maintenance on crushers, mills, conveyors, pumps, fans, and haulage.

• Establish backup/restore, configuration management, spare parts strategy, and site disaster recovery for OT.

Project Delivery & Stakeholder Management
Documentation, Training & Handover

• Produce engineering Lead end‑to‑end OT projects (brownfield upgrades, expansions, greenfield) using PMP/Agile practices; manage scope, schedule, budget, risk.

• Coordinate OEMs, EPCs, system integrators, and site operations; run change control/MOC and quality gates.

• packs (SDS/FDS, network drawings, cybersecurity policies, test records, as‑builts).

• Train control room operators, maintainers, and supervisors; build run‑books and SOPs.

Qualifications - Must‑Have

• Bachelor's in electrical/Instrumentation/Control/Mechatronics (or similar).
• 5-8+ years in mining automation/OT across plant and/or pit operations.
• Hands‑on with SCADA/DCS/PLC: e.g., Siemens PCS 7 / TIA‑Portal (S7‑1500), Rockwell PlantPAx / ControlLogix, ABB 800xA, Yokogawa CENTUM, or Ignition/AVEVA System Platform/GE iFIX/Citect.
• Protocols & data: OPC UA, MQTT, Modbus (TCP/RTU), EtherNet‑IP, PROFINET, serial, and PI/AVEVA Historian (or similar).
• Networking (industrial Ethernet, VLANs, redundancy, firewalls), time sync (PTP/NTP), and virtualization/backup in OT.
• Demonstrated commissioning experience in harsh/mining environments (dust, vibration, temperature, limited visibility).

Nice‑to‑Have (Mining‑Specific)

• FMS / Guidance / CAS: Wenco, Modular/Komatsu DISPATCH, Cat MineStar, Hexagon, MICROMINE Pitram; proximity detection and CAS Level‑9 ecosystems.
• Hoist/Winder, VoD, Dewatering automation; weighbridges/belt scales/custody.
• Edge/IIoT, Python scripting, SQL, Power BI; Azure/AWS industrial services.
• CMMS/EAM (SAP PM, IBM Maximo, IFS) integration; reliability engineering practices (RCM/CBM).

Certifications (Preferred)

• TUV Functional Safety Engineer (IEC 61511/61508) or ISA Functional Safety.

• ISA/IEC 62443 Cybersecurity; GICSP or equivalent.

• Vendor certifications (Rockwell/Siemens/ABB/Yokogawa), CCNA Industrial, PMP/PMI‑ACP.

Working Conditions

• Regular travel to remote mine sites (open‑pit/underground), occasional rotations.

• Field work at heights, near heavy mobile equipment, in dusty/noisy areas; use of PPE, fit for work.

• After‑hours/on‑call support during shutdowns, cutovers, and production upsets.
