EPMS implementation Role Overview We are looking for a senior skilled 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.

How data is collected
What communication protocols are being used
How systems differ from one site to another 2. Connect data to the right equipment
SCADA systems generate thousands of data points called tags. Create and maintain the mapping between tags and the physical machine/equipment they belong to, so the organisation always knows which data belongs to which asset. 3. Organise and clean the data
