About the role

  • Connect to OT sources: PLCs, SCADA, DCS, industrial sensors, historians, and machine controllers.
  • Configure and troubleshoot industrial connectivity using protocols such as OPC UA/DA, MQTT (Sparkplug B), Modbus TCP/RTU, EtherNet/IP, PROFINET, and REST APIs (where applicable).
  • Implement tagging standards and support tag governance (naming conventions, units, sampling, quality flags, timestamps).
  • Deploy and configure edge runtimes and gateways (on industrial PCs/VMs): Litmus Edge, Ignition Edge, Kepware/KEPServerEX, HiveMQ/Mosquitto, Azure IoT Edge / AWS Greengrass (as relevant).
  • Build edge workflows for buffering, filtering, enrichment, and routing using Node-RED, Python, scripting, connectors, store-and-forward patterns.
  • Ensure resilient edge operations: offline buffering, retry logic, local persistence, health monitoring.
  • Configure and develop solutions within OT/IIoT platforms such as PTC ThingWorx (modeling, connectivity, mashups/services), Sight Machine (data onboarding, model alignment, analytics enablement), Inductive Automation Ignition (tags, gateways, OPC/MQTT modules, UIs), Litmus (connectors, pipelines, edge analytics), Mendix (lightweight apps/workflows on top of OT data).
  • Implement end-to-end ingestion pipelines: From L0–L2 signals (machines) > edge > OT platform > cloud ingestion.
  • Validate payload formats, schemas, batching, compression, and frequency to meet performance needs.
  • Support cloud ingestion patterns using Azure (IoT Hub/Event Hubs, Functions, Data Lake, Databricks/Synapse), AWS (IoT Core/Kinesis, Lambda, S3/Glue), Integration into Snowflake (via streaming/batch connectors where relevant).
  • Implement data quality checks: completeness, duplication, timestamp drift, unit consistency, gap detection.
  • Work on-site (or remote to site edge systems) to support: Installation, configuration, commissioning, and integration testing, Firewall/network coordination with Site IT (ports, routes, certs, proxies).
  • Troubleshoot connectivity and performance across the full chain (OT > edge > platform > cloud).
  • Document configurations, runbooks, and handover packages for operations/support teams.

Requirements

  • 4–8+ years in OT/industrial integration roles with hands-on delivery in manufacturing environments.
  • Strong practical experience with at least two of the following:
  • ThingWorx, Ignition, Litmus, Sight Machine, Mendix
  • Proven experience building integration flows using Node-RED (or equivalent low-code orchestration) plus scripting (Python preferred).
  • Solid understanding of OT systems and protocols (OPC UA, MQTT, Modbus, etc.) and the realities of plant networks.
  • Comfortable working with multiple stakeholders (OT, IT, Security, OEMs, System Integrators) in a global environment.
