AI Enablement Engineer

Location: Pune, India

Department: AI Enablement

Experience: 3-5

• 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.

• Bachelors 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.

• 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.
