Integration Architecture Design

JD - Integration architect from utility domain background

Key Responsibilities

• Define the target integration architecture across HES, EnergyIP MDMS, SAP PO, SAP HANA, GIS and other enterprise systems (billing/CRM/DWH as applicable).
• Select and standardize integration patterns: API-led , event/message-based , batch , file-based , near-real-time streaming , and hybrid models.
• Define canonical data model and transformation strategy (meter events, interval reads, alarms, device lifecycle, network topology references).
• Define interface contracts : message schemas, API specifications, payload validation rules, versioning, backward compatibility.

2) Interface Governance

• Architect and govern integrations implemented via mappings, adapters, routing, error-handling, retries).
• Define integration standards for:
• SOAP/REST , IDoc , RFC , JMS , SFTP , ODBC/JDBC (as applicable)
• Establish reusable components (common mappings, error-handling frameworks, logging standards, correlation IDs).
• Design and validate end-to-end flows for:
• Interval and register reads (bulk + incremental)
• Device lifecycle (install, replace, remove, firmware/config)
• Commands (connect/disconnect, on-demand reads, parameter updates)
• GIS topology and asset references (feeder/transformer connectivity, spatial attributes)

4) Non-Functional Requirements (NFR) Ownership

• Define and ensure compliance with NFRs:
• Performance (throughput, latency, peak handling)
• Scalability (horizontal scaling, partitioning, batching strategy)
• Security (encryption, certs, OAuth/SAML as applicable, key rotation)
• Observability (monitoring, alerting, audit logs, integration KPIs)
• Define capacity sizing inputs for integration layer: message volume/day, peak reads, file sizes, concurrent interfaces.

6) Delivery Support, Testing, Cutover & Hypercare

• Lead integration workshops with business/IT/vendors to finalize interface requirements and sequencing.
• Own the integration test strategy:
• SIT, end-to-end testing, performance testing, failover testing
• Test data preparation and reconciliation approach
• Support cutover planning, data migration and synchronization, rollback strategy.
• Provide L3 support guidance during hypercare for interface failures and performance issues.

Required Skills & Qualifications

Must-Have (Technical)

• 12+ years in integration architecture across enterprise platforms.
• Strong experience in AMI/MDMS integrations (EnergyIP preferred) or similar high-volume telemetry/data platforms.
• Strong hands-on architecture knowledge of:
• integration patterns (data replication, interfaces, data services)
• API design (REST/SOAP), message-based integration (JMS/Kafka-like concepts)
• Data formats: XML , JSON , CSV , schema governance and versioning
• Experience in high-volume ingestion and processing:
• Batch tuning, incremental loads, partitioning, compression strategies
• Handling late/missing reads and estimation flags
• Integration security knowledge:
• TLS/mTLS , certificates, OAuth2/token-based auth (where applicable), secure service accounts

Must-Have (Architecture & Delivery)

• Proven ability to define integration standards, canonical models, and enforce governance.
• Strong knowledge of NFR engineering: performance, DR, monitoring, resiliency patterns.
• Experience leading cross-functional workshops and producing architecture artifacts.

Education & Certifications

• Bachelor’s degree in Engineering/Computer Science (Master’s preferred).
• Preferred certifications:
• Cloud/Integration certifications (if relevant)
