AI Enablement Engineer

Location

Pune

Role Summary

The IoT Engineer will design, implement, and maintain shopfloor data acquisition and integration solutions across PLC/SCADA/DCS systems, enabling reliable, secure IIoT pipelines to edge and cloud. The role requires hands‑on expertise in Node‑RED, industrial networking, OPC (DA/UA), Kepware, SQL, and scripting with Python and JavaScript to build resilient integrations, historians, and real‑time dashboards.

Key Responsibilities

• Design and implement IIoT data flows from PLC/SCADA/DCS to edge, historian, and cloud using Node‑RED, OPC UA/DA, Kepware, MQTT/REST, and SQL‑backed stores.
• Collect data from shopfloor systems including PLCs, SCADA/DCS, local file systems, sensors, and test benches, ensuring reliable and secure acquisition.
• Integrate via industrial protocols and interfaces: OPC UA/DA, Modbus TCP/RTU, Profinet, EtherNet/IP, MQTT, and file drops (CSV/JSON), with read/write where safe.
• Build reusable Node‑RED flows/subflows for device onboarding, health checks, buffering, alerting, and REST/MQTT bridges; maintain versioned configs.
• Collaborate with controls teams to safely access PLC tags and verify mappings against ladder/FB logic, SCADA/DCS points, and SOPs.
• Validate data quality and lineage end‑to‑end; monitor latency, gaps, drift, and packet loss; drive root‑cause analysis and corrective actions.
• Develop edge apps/microservices in Python and JavaScript for parsing, normalization, store‑and‑forward, and health monitoring; integrate with SQL databases and time‑series stores.
• Establish monitoring for data quality, latency, uptime, packet loss; implement logging, metrics, alerting, and SQL‑based data validation.
• Produce documentation: network diagrams, data flow maps, tag dictionaries, SQL schemas, SOPs, and runbooks; train plant users.
• Support commissioning, FAT/SAT, and on‑call troubleshooting; drive root‑cause analysis and corrective actions.
• Ensure compliance with cybersecurity and safety standards; manage credentialing, certificates, and least‑privilege access.

Required Qualifications

• Bachelor's in Electrical/Electronics/Instrumentation/CS or equivalent.
• 4+ years in industrial automation/IIoT integrating PLC/SCADA/DCS with IT systems and databases.
• Strong Node‑RED experience (flows, subflows, context, error handling, MQTT/HTTP nodes).
• PLC ecosystems: Siemens S7, Rockwell ControlLogix/CompactLogix, Mitsubishi, Schneider, or ABB.
• Protocols: OPC UA/DA, Modbus TCP/RTU, Profinet, EtherNet/IP, MQTT; serial‑to‑IP gateways.
• Kepware configuration and administration; performance tuning and diagnostics.
• SCADA/DCS exposure: tag engineering, alarms, historian (e.g., Ignition, WinCC, FactoryTalk, AVEVA/PI).
• SQL proficiency: schema design, indexing, query optimization, stored procedures, and data integrity for PostgreSQL/MySQL/MS SQL; familiarity with time‑series DBs is a plus.
• Programming: Python (pandas, asyncio, pyserial/opcua), JavaScript/Node.js for edge services and APIs.
• Networking: L2/L3 switching, VLANs, QoS, ACLs, routing basics, Wireshark/Tcpdump, NTP, SNMP; grounding/EMI awareness.
• Strong troubleshooting across OT devices, drivers, networks, databases, and data pipelines; clear stakeholder communication.

Good To Have Skills

• Ignition development, FactoryTalk, WinCC, or Wonderware experience.
• MQTT Sparkplug B, Kafka, TimescaleDB/InfluxDB, Grafana/Power BI.
• Windows/Linux administration on edge nodes; hardening and patching.
• Cloud IoT services (AWS/Azure/GCP) and REST/GraphQL integration.
• IEC 62443, ISA‑95/88, change control/validation practices.
• Basics of controls safety for safe reads/writes and handshakes.
• Version control (Git), CI/CD basics, containerization familiarity (Docker) for edge deployments.
