This role involves remote troubleshooting, system monitoring, and deployment support for critical OT infrastructure including weighbridges (road delivery) and conveyor systems (belt delivery).

Operating within a high-trust, customer-facing environment, the engineer ensures rapid incident response, accurate resolution, and exceptional service delivery to maintain uptime and operational continuity across all supported sites.

ROLE REQUIREMENT

Respond to monitoring alerts, initiate corrective actions, and restore system functionality.

Maintain and document system health reports, alert events, and performance analytics.

Deployment and Installation Support

Support the deployment, configuration, and validation of OT systems, site gateways, and software updates.

Coordinate with field technicians to ensure smooth site installations and system upgrades.

Document process steps, test results, and validation outcomes.

Service Desk and SLA Management

Triage, validate, and respond to incoming support tickets via service management platforms (e.g. ServiceNow, Remedy).

Prioritise tasks in line with Service Level Agreements (SLAs) and business impact.

Accurately record incident details, troubleshooting steps, and resolutions in the knowledge base.

Ensure proper escalation and collaboration with 2nd line, DevOps, or product teams for unresolved or complex issues.
