business rules, and API contracts.* Establish OpenAPI 3.0 specifications and REST API standards suitable for external partner consumption with versioning, backward compatibility, and SLA guarantees.* Lead architecture and implementation of large-scale customer account migration platform supporting multi-million account migrations across CIS/billing systems.* Design and build data seeding/bootstrap, bi-directional synchronization, reconciliation logic, and phased cutover strategies with rollback capabilities for CIS migrations.* Build migration orchestration workflows handling dependencies across customer, billing, payment, identity, and field service domains with data quality validation and discrepancy detection.* Build production-grade integration clients for z/OS mainframe systems using z/OS Connect, CICS transactions, MQ messaging, and batch file exchanges.* Implement resilience patterns for mainframe connectivity including circuit breakers, retries, timeout handling, and graceful degradation supporting utility-scale transaction volumes.* Handle mainframe-specific integration challenges: EBCDIC/ASCII conversion, copybook parsing, fixed-length record formats, transaction coordination, connection pooling, and batching.* Develop core middleware framework built on Spring Boot 3.X+ and Java 21+ with standardized libraries for OAuth2 security, Azure Key Vault secrets management, structured JSON logging, and distributed tracing.* Create CI/CD pipeline templates, Helm chart standards, and blue/green deployment patterns for Kubernetes/OpenShift with horizontal scaling and high availability.* Integrate observability tooling: Splunk, Dynatrace APM, Prometheus/Grafana, Jaeger with SLO/SLA monitoring patterns and runbook templates.* Provide comprehensive documentation, code samples, migration guides, and developer onboarding materials.* Conduct framework design reviews, establish governance standards, and mentor engineers on platform usage and best practices.**Required Skills & Experience*** 10-15 years building enterprise-grade middleware platforms, with at least 5 years architecting multi-tenant platforms designed as reusable

z/OS Connect, CICS transactions, MQ messaging, batch processing, EBCDIC/ASCII conversion, copybook parsing, and mainframe-specific error handling patterns.* Deep domain expertise across enterprise customer platforms including at least 4 of: CIS, billing systems, payment processing, identity/authentication, customer care, field service management, or account management platforms in utility, telecom, financial services, or regulated industries.* Deep expertise in Spring Boot 3.X ecosystem (Spring Security, Spring Data, Spring Cloud) with proven ability to architect shared frameworks adopted by multiple teams.* Expertise in multi-tenant architecture patterns: tenant-level routing, security isolation, data segregation, resource quotas, rate limiting, and partner-specific configuration management.* Experience designing abstraction layers normalizing differences across multiple backend systems with dynamic routing logic based on account-level or entity-level attributes.* Extensive experience with distributed systems patterns (circuit breakers, retries, bulkheads, caching, event-driven architecture), container orchestration (Kubernetes/OpenShift), and cloud platforms (Azure, AWS, GCP).* Expertise in REST API design for partner-facing platforms: OpenAPI specifications, versioning strategies, backward compatibility management, SLA guarantees.* Hands-on experience with observability tools (APM, logging aggregation, distributed tracing, metrics) and establishing SLO/SLA monitoring for platform services.* Strong knowledge of OAuth2/OIDC, secrets management (Azure Key Vault), and secure coding practices for multi-tenant environments.**Nice to Have*** Experience with Oracle GoldenGate CDC, Informatica, or similar data replication
