JOB OVERVIEW

Ontario Power Generation (OPG) is looking for a dynamic, strategic and results-driven professional to join our team in the role of Senior Integration Services Developer.

Reporting to the Senior Manager Projects, this position is responsible to own the end-to-end integration capability on SAP Integration Suite (CPI/BTP)—designing integration architecture and iFlows, managing API lifecycles, delivering complex data transformations (Message Mapping/Groovy/XSLT), enabling secure hybrid connectivity via SAP Cloud Connector across SAP and non-SAP systems, and providing L2/L3 production support aligned to security best practices and “Clean Core” standards.

KEY ACCOUNTABILITIES

• Build, configure, test, and deploy scalable integration flows in SAP Integration Suite (CPI) to meet business and technical requirements.
• Create, publish, version, and retire APIs; enforce governance, documentation, and consumption standards across the API portfolio.
• Develop and maintain message mappings and transformations using Message Mapping, Groovy scripting, and XSLT to ensure accurate, consistent data exchange.
• Enable reliable connectivity between SAP systems (S/4HANA, SuccessFactors, FieldGlass) and non-SAP platforms (e.g., ServiceNow), including network and routing considerations.
• Configure and administer SAP Cloud Connector, including subaccount mappings, exposed resources, access controls, and connectivity troubleshooting.
• Define integration patterns and architecture decisions; produce technical design documents and specifications aligned with enterprise standards.
• Troubleshoot and resolve complex production issues, perform root cause analysis, implement fixes, and proactively improve stability and performance.
• Implement and maintain secure authentication/authorization (OAuth flows, certificates, key management), and ensure integrations adhere to SAP best practices and “Clean Core” principles.

QUALIFICATIONS

• 4 Year bachelor’s degree in computer science, Engineering, or a related discipline. Relevant certifications in Azure integration technologies are considered an asset.
• 6+ years of experience delivering SAP Integration Suite (CPI/BTP) integrations, including API management, data transformations (Groovy/XSLT), hybrid connectivity via SAP Cloud Connector, L2/L3 support, and secure “Clean Core” practices.
• Proven expertise in API lifecycle management (design, versioning, publishing, governance) and integration best practices.
• Strong data mapping/transformation skills using Message Mapping, Groovy scripting, and XSLT.
• Demonstrated experience integrating SAP applications (S/4HANA, SuccessFactors, FieldGlass) with non-SAP systems (e.g., ServiceNow) in hybrid landscapes.
• Hands‑on capability configuring and troubleshooting SAP Cloud Connector connectivity, routing, and access controls.
• Strong technical leadership in integration architecture and specifications, with L2/L3 production support experience and solid security implementation (OAuth, certificates) aligned to “Clean Core” standards.
