Contract OT & IoT IT Engineer (Manufacturing Systems Support)

This role is to support one of our clients in a manufacturing environment. The incumbent will provide dedicated onsite Level 2 / Level 2.5 technical support for manufacturing IT and OT/IoT systems, including software, hardware, networks, gateways, dashboards and eDHR-related infrastructure.

The successful talent will support production stability, system go-live and stabilization, rapid troubleshooting and issue resolution, while coordinating with local manufacturing teams, regional and global IT/solution teams and third-party vendors.

Roles & Responsibilities

OT/IoT Infrastructure & Network Support

• Support implementation and stabilization of OT/IoT infrastructure, including industrial Ethernet/Wi-Fi, IP addressing, re-IP activities, network segmentation and connectivity between machines, sensors, gateways and shop-floor systems.

• Configure and troubleshoot industrial network connectivity and support readiness for IoT data flow, eDHR execution, and OEE monitoring.

• Coordinate with EIT, OT, Security, Infrastructure, application, solution and vendor teams on OT security, DMZ, access, connectivity, and escalation requirements.

OT/IoT Systems & Device Support

• Deploy, configure, maintain and troubleshoot OT/IoT software and hardware, including Tulip applications/stations/connectors/interfaces, Litmus edge software and gateways, and Grafana dashboards.

• Support manufacturing devices and peripherals, including tablets, barcode scanners, industrial printers, displays, industrial PCs, engineering workstations, gateways and sensors.

• Perform onsite installation, configuration, testing, replacement, preventive checks and break-fix support.

• Monitor system and device availability and validate end-to-end data flow from machines and sensors through gateways/platforms to dashboard displays.

Incident Troubleshooting & Escalation

• Provide initial diagnosis, issue isolation and service restoration for Tulip, Litmus, Grafana, OT network, hardware, devices, infrastructure, access, integration and data-visibility issues.

• Identify whether incidents relate to software, hardware, network, data source, integration, access, or infrastructure and route them to the appropriate support owner.

• Collect relevant troubleshooting information such as timestamps, screenshots, logs, error messages, device status, network checks, recent changes and business impact.

• Escalate application defects, integration failures, platform issues or advanced network problems to the appropriate Level 3 application, solution, infrastructure or vendor teams, supported by clear technical findings.

• Track incidents through resolution and validate service recovery with manufacturing users.

Documentation & Knowledge Management

• Maintain known-error, configuration, troubleshooting and support handover documentation.

Onsite & Evening Shift Support

• Provide onsite support during the assigned evening shift, including production ramp-up, testing, go-live stabilization, and prompt response to production-impacting incidents.

• Act as a time-zone bridge between manufacturing users/engineers, HCL L1 support, and global or regional application/solution teams, including HCL and PwC, where applicable.

Other Responsibilities

• Perform other tasks reasonably required within the contracted manufacturing systems support scope.

Requirements & Skills

• Diploma or Bachelor’s Degree in Computer Science, Information Technology, Engineering or related field.

• Minimum 3 years of relevant experience supporting IT hardware/software, OT/industrial IT or manufacturing systems.

• Practical exposure to IoT platforms, MES/eDHR, industrial networking, go-live or production ramp-up support is preferred.

• Working knowledge of industrial networking, including Ethernet, switches, VLANs, IP addressing, Wi-Fi, network segmentation and basic firewall-path troubleshooting.

• Experience in OT/IoT support, hardware/software troubleshooting, incident diagnosis, log collection, escalation and service recovery.

• Exposure to Tulip, Litmus, Grafana or similar IoT, edge, dashboard, MES or eDHR platforms is an advantage.

• Able to support industrial devices such as gateways, sensors, workstations, tablets, scanners, printers and display screens.

• Good communication, customer service, and problem-solving skills with the ability to work independently during off-peak hours.

• Able to work within corporate IT security and regulated manufacturing requirements.
