Senior Integration Architect - Historian Platforms

Role Overview :

We are looking for a senior professional who understands SCADA, BMS, EPMS and industrial data systems, and who can help the organisation bring data from different sites and equipment into a common enterprise data platform.

In simple terms : you will take data coming from machines, BMS/SCADA systems and sensors, organise and clean it, connect it securely to the company's data platform, and make sure it can be used reliably for business and operational decisions.

The role is to architect and standardise how SCADA/BMS/EPMS data from multiple sites is collected, mapped to physical assets, cleaned, secured and transferred into the enterprise data platform so that Operations and business teams can use reliable KPIs and analytics.

Key Responsibilities : 1. Understand the existing SCADA/BMS systems :

• Study the systems in use across different sites and document SCADA/BMS/EPMS systems, controllers, equipment, historian systems, data collection methods, and communication protocols.

2. Connect data to the right equipment :

• Create and maintain the mapping between SCADA tags and the physical machine/equipment they belong to.

3. Organise and clean the data :

• Define how the data should be collected, stored, cleaned, standardised, aggregated, downsampled, and validated, following the organisation's Bronze - Silver - Gold data model.

4. Ensure the data is accurate :

• Identify and resolve data quality issues, including incorrect readings, missing data, incorrect timestamps, and measurement unit discrepancies.

5. Work with Cybersecurity :

• Ensure data is extracted without affecting the operation or security of the equipment, working with cybersecurity teams on network segmentation, OT/IT separation, and secure data extraction.

6. Define operational KPIs :

• Work with Operations and Engineering teams to convert machine data into meaningful operational metrics such as power consumption, cooling performance, and equipment availability.

7. Support data pipelines :

• Work with the data engineering team to ensure OT data flows correctly from SCADA/BMS to the Data Platform and Analytics/Dashboards.

Required Experience : 1. Must Have :

• 16+ years of overall experience

• At least 5+ years working with SCADA, BMS, EPMS or industrial historian systems

• Experience working with industrial/OT data and integrating OT data with IT/data platforms

• Good understanding of asset hierarchy and tag mapping

• Experience with industrial communication protocols such as Modbus, BACnet, OPC UA / OPC DA, MQTT

• Experience with historian platforms such as OSIsoft PI / AVEVA PI, Ignition, or equivalent

• Understanding of OT cybersecurity and IT/OT network segregation

2. Good to Have :

• Experience with large-scale industrial/data-centre environments, cloud/data platforms, data lakes, and time-series data

• Experience with data quality frameworks and building operational dashboards/KPIs
