Exp- 16-20 yrs

Primary Focus Areas
SCADA systems integration
BMS architecture design
EPMS implementation

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 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 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:
What SCADA/BMS/EPMS systems are installed
What controllers and equipment are connected
What historian systems are being used
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
Data arrives from many different sites and systems. Define how the data should be collected stored cleaned standardised aggregated downsampled and validated following the organisation's Bronze → Silver → Gold data model:
Bronze: Raw data
Silver: Clean and validated data
Gold: Business-ready information / KPIs

Sensors giving incorrect readings
Missing data
Sensors stuck at the same value
Incorrect timestamps
Different measurement units
Duplicate or abnormal readings
Also help create a confidence score for important operational KPIs so the data can be trusted.

SCADA and BMS systems are part of the OT (Operational Technology) environment. Ensure data is extracted without affecting the operation or security of the equipment working with cybersecurity teams on:
Network segmentation
OT/IT separation
One-way data transfer where required
Secure data extraction
OT cybersecurity controls

6. Define operational KPIs
Work with Operations and Engineering teams to decide what should be measured and how converting machine data into meaningful operational metrics such as:
Power consumption
Cooling performance
Equipment availability
Capacity
Energy efficiency
System reliability

7. Support data pipelines
Work with the data engineering team to ensure OT data flows correctly from SCADA/BMS → Data Platform → Analytics/Dashboards. Support:
Data pipeline development
Monitoring
Error detection
Automated testing
Data quality checks
