- Develop ingestion services using AWS IoT SiteWise, IoT Greengrass and AWS IoT Core, including device registry, policies and message routing.
- Deliver OT/IT integration and data ingestion for plants, bridging controller, SCADA and historian systems to the cloud securely.
- Produce deployable edge and local application blueprints that can be rolled out to new plants and lines.
- Develop edge ingestion services using AWS IoT Greengrass and AWS IoT SiteWise (must have), including components, stream management and local processing.
- Implement the standardised edge-to-cloud data pipeline (the mandatory ingestion path) with consistent naming, timestamps, units and quality codes.
- Integrate with PLC/DCS and SCADA systems via OPC-UA, MQTT or historian interfaces; configure device connectivity and telemetry collection.

Resilience and performance

- Ensure resilient, low-latency transfer from OT to cloud: local buffering, store-and-forward, back-fill after outages, retry policies and time synchronisation.
- Size and test throughput and latency per site; monitor ingestion health, data gaps and device status.
- Build containerised applications for on-premise plant deployment; manage images, configuration and secrets for constrained or restricted environments.
- Package reusable edge deployment blueprints and templates so a new plant or line is deployed through automation with no manual steps.
- Implement secure provisioning and updates: certificate-based device identity, fleet provisioning, over-the-air updates and rollback.





Plant integration and operations

- Work within plant network zones (Purdue model, DMZ, outbound-only connectivity) with OT, IT and security teams; follow plant change and safety procedures.
- Lead commissioning and site acceptance testing; create runbooks and train plant support teams.
- Map plant tags to canonical assets with the Semantic Architecture team, using the approved signal-mapping process.

Required qualifications and experienceMust have

- Hands-on experience with AWS IoT Greengrass and AWS IoT SiteWise (must have).
- Experience building containerised applications with Docker for on-premise or edge deployment.
- Practical knowledge of industrial protocols and interfaces: OPC-UA, MQTT and historian connectors.
- Programming experience in Python or Node.js for edge components and integration.
- Experience designing buffering, retry and offline-tolerant data pipelines.
- Hands-on experience with AWS IoT Core alongside Greengrass and SiteWise.
- Bachelor’s degree in Electronics, Instrumentation, Computer Science or equivalent experience.

Good to have

- Experience in plant environments: PLC, DCS, SCADA and historian systems (for example Siemens, Rockwell, Honeywell, Yokogawa, ABB, Emerson, OSIsoft PI).
- Sparkplug B, Modbus, EtherNet/IP; lightweight Kubernetes (k3s) at the edge.
- IEC 62443 and Purdue-model network design; secure remote access to plants.
- Terraform or similar IaC for fleet provisioning and edge deployment.
