Location: [Chile, Santiago]

Job Description: OT Systems Engineer – Control Systems & Field Integration

Role Summary

Work Mode

Hybrid (combination of remote and on-site work)

The OT Systems Engineer designs, integrates, and sustains mining OT environments SCADA/DCS/PLC systems, field instrumentation, and site communications ensuring safe, reliable, and cyber secure operations across pits, plants, and load out/rail. Leads the OT/IT convergence, data integration to historians/MES/FMS, and enable “digital mine” initiatives including IIoT, condition monitoring, and analytics to reduce downtime and improve throughput all in compliance with mining safety and functional safety standards.

Work closely with Network Architect, FO Specialist, Solution Architect (IT/OT) & Cybersecurity assessments drives with in the project scope and requirements.

Key Responsibilities

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 (CH, 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.
