Brief DescripƟon:
The IntegraƟon Engineer is responsible for enabling seamless data and workflow integraƟon
between manufacturing systems, enterprise applicaƟons, and plant-level automaƟon systems.
The ideal candidate will have a strong background in either computer science or chemical
engineering with hands-on experience in system integraƟon, preferably using tools like BizTalk,
and should understand refinery or oil & gas operaƟons.
ResponsibiliƟes:
 Design, develop, and maintain integraƟons between manufacturing systems (MES,
LIMS, CMMS, DCS, SCADA) and enterprise systems (ERP, SAP, cloud plaƞorms).
 Understand plant workflows in refining or oil & gas and translate them into
integraƟon logic.
 Work with OT systems like PLCs, DCS, SCADA, and historians (PI, IP.21, PHD) to enable
secure and structured data flow.
 Develop API-based interfaces and messaging workflows using tools such as BizTalk,
MuleSoŌ, or Azure IntegraƟon Services.
 Implement and maintain data mappings, transformaƟon logic, and message rouƟng
between systems.
 Create interface control documents, test cases, and sequence diagrams for
integraƟon scenarios.
 Ensure system integraƟon follows standards such as ISA-95, B2MML, OPC UA, and
ISA-88.
 Collaborate with control systems, IT, and business teams for alignment on
architecture and data governance.
 Perform system and integraƟon tesƟng, including Factory Acceptance TesƟng (FAT)
and Site Acceptance TesƟng (SAT).
 Monitor and troubleshoot integraƟon failures; ensure high availability and reliability
of interfaces.
Preferred Candidate:
 Bachelor’s degree in computer science, Information Technology, or Chemical
Engineering with strong coding/integration skills.
 4+ years of experience in system integration in the refinery, petrochemical, or oil &
gas industry.
 Experience with BizTalk Server, or equivalent integration platforms (MuleSoft, Azure
Integration, Boomi).
 Knowledge of communication protocols such as OPC (UA/DA), MQTT, REST/SOAP,
and industrial data formats (XML, JSON).
 Exposure to SAP modules like PM, MM, PP, and QM in manufacturing or
maintenance contexts.
 Working knowledge of plant automation systems and process workflows.
 Strong scripting or programming background (C#, Python, PowerShell, or
equivalent).
 Understanding of cybersecurity and network considerations for IT/OT integration.
Desired Skills:
 Familiarity with manufacturing execuƟon systems (MES), laboratory informaƟon
management systems (LIMS), and computerized maintenance systems (CMMS).
 Experience with data contextualizaƟon and Ɵme-series databases.
 Understanding of refinery operaƟons such as unit producƟon, maintenance cycles,
quality checks, and inventory movements.
 CerƟficaƟons in OPC, Azure IntegraƟon, or SAP integraƟon tools are a plus.
 Strong communicaƟon and documentaƟon skills, especially for working across IT, OT,
and process engineering teams.
