Core Responsibilities

Primary Functions

Lead end-to-end integration architecture and solution design across SAP S/4HANA/ECC and non-SAP systems using SAP PI/PO and SAP Cloud Platform Integration (CPI) / Integration Suite; produce solution blueprints, sequence diagrams, interface contracts and non-functional requirement (NFR) specifications.
Drive hands-on development and delivery of complex interfaces (IDoc, RFC, BAPI, SOAP, REST, OData) including message mapping, value mapping, XSLT/graphical mapping and transformation logic in ESR, Integration Directory and CPI integration flows.
Architect and implement API-led connectivity and API Management solutions for SAP and third-party consumption, including API design, security policies (OAuth2, JWT, mTLS), rate limiting, and developer portal onboarding.
Design and implement B2B/EDI and AS2 solutions for supplier/customer integrations; configure EDI converters, partner profiles and ensure compliance with industry standards (EDIFACT, X12).
Lead migration of integration landscape from PI/PO to SAP CPI/Integration Suite or to cloud-native iPaaS; create migration strategy, mappings, automated test plans and cutover procedures.
Define integration patterns, governance standards, naming conventions, transport & versioning strategy and runbook templates to ensure operational consistency across teams and environments.
Manage interface builds using adapters (IDoc, RFC, SOAP, HTTP, SFTP, JMS, OData) and integrate with middleware components such as JMS brokers, message queues and ESB services.
Own performance tuning, throughput optimization and scalability planning for integration processes; monitor end-to-end message latency, investigate bottlenecks and propose remediation across SAP application, network and middleware layers.
Implement secure certificate management, key rollover, encryption, signing and PKI integrations for secure SOAP, AS2 and HTTPS communication channels.
Lead unit/system/integration testing (SIT) and support User Acceptance Testing (UAT) for interfaces; create and execute test cases, coordinate defect resolution and maintain traceability between requirements and test artifacts.
Establish CI/CD pipelines and automated deployments for integration artifacts using Git, Jenkins, or Azure DevOps; manage transports, automated unit tests and rollback strategies.
Provide 3rd-level support and on-call leadership for production integrations; diagnose runtime errors, perform root cause analysis and coordinate quick resolution with application, infrastructure and vendor teams.
Mentor and coach junior integration consultants and offshore teams; perform design/code reviews, knowledge transfers, and train internal stakeholders on integration patterns and toolsets.
Collaborate with functional leads, business analysts and process owners to translate business requirements into robust integration solutions and interface designs, ensuring data integrity and SLA alignment.
Manage vendor & partner relationships for integration components (managed services, middleware vendors); evaluate third-party products, run POCs and support procurement decisions.
Prepare high-quality technical documentation: interface specs, sequence flows, mapping specs, configuration guides and operational runbooks to support onboarding and audits.
Plan and lead cutover/migration activities for system upgrades, S/4HANA migrations and landscape harmonization projects; coordinate dependency management and risk mitigation with cross-functional teams.
Design and implement end-to-end monitoring and observability for integration processes using SAP Solution Manager, CPI Monitoring, Cloud ALM, Splunk or equivalent tools to enable proactive incident detection.
Ensure compliance with security, audit and regulatory requirements in integrations (PII, GDPR); conduct security reviews and remediate vulnerabilities related to data in transit and protocol security.
Drive cost optimization and technical debt reduction in the integration landscape by consolidating interfaces, removing redundant adapters and rationalizing legacy middleware.
Estimate workstreams, create integration delivery plans and resource forecasts for project proposals and change requests; provide input to effort estimation, timelines and acceptance criteria.
Lead cross-functional workshops and architecture reviews to socialize integration designs, obtain stakeholder approvals and ensure alignment with enterprise architecture and cloud strategies.
Champion continuous improvement initiatives: introduce reusable integration templates, accelerate delivery with pre-built interface accelerators and maintain a reusable integration component library.

Secondary Functions

Support ad-hoc integration requests, exploratory interface investigations and quick POC builds to validate technical feasibility for new business scenarios.
Contribute to the organization's integration strategy, roadmap and migration plan from on-premise middleware to cloud integration platforms.
Collaborate with business units to translate data exchange needs into technical integration requirements and acceptance criteria.
Participate in sprint planning, backlog grooming and agile ceremonies to ensure integration deliverables are prioritized and aligned with release milestones.
Produce training materials and facilitate knowledge-transfer sessions for functional teams, support staff and end users on interface behaviors and error handling.
Assist in vendor evaluations, RFP responses and piloting of new iPaaS or API management tools to support future integration capabilities.
Participate in post-go-live retrospectives and continuous improvement initiatives to reduce incidents and improve time-to-resolution.
Support data mapping validations and reconcile interface data during parallel runs and migration exercises.
Help define SLAs, KPIs and operational dashboards for integration health and business transaction visibility.
Act as a liaison between infrastructure, security and application teams to ensure integrated deployments meet enterprise operational standards.
