Senior System Architect: Cloud-Native Microservices Leader

The Sr. System Architect serves as the Technical Design Authority, bridging the gap between enterprise architecture strategy and engineering delivery. This is a “boots-on-the-ground” leadership role responsible for defining detailed technical blueprints—including microservices design, cloud-native patterns, and API contracts—required to modernize mission-critical systems. You will lead the migration of legacy IBM Mainframe/TPF environments into a modern Java and Spring-based event-driven architecture (EDA), ensuring architectural integrity throughout the engineering lifecycle. Primary Responsibilities Translate high-level business capabilities into detailed technical specifications for microservices, integration patterns, and cloud-native architectures. Lead the technical design and execution for replacing legacy systems with scalable Java and Spring Boot microservices. Design and govern robust API contracts and integration patterns to enable seamless, real-time communication across heterogeneous, multi-domain environments. Maintain deep visibility into the engineering lifecycle. Partner with development teams to ensure implementations adhere to architectural standards for reusability, scalability, and performance. Apply industry-standard frameworks (TOGAF, BizBok, DAMA/DMBok) to ensure alignment with enterprise data and business standards. Provide technical leadership in a Scaled Agile (SAFe) environment, aligning the architectural runway with Program Increment (PI) planning and continuous delivery. Minimum Qualifications 15+ years of progressive IT experience, including 10+ years in technology/system architecture. Proven experience defining and implementing technology solutions for large-scale, complex systems. Demonstrated track record of migrating IBM Mainframe/TPF workloads to Event-Driven Architectures (EDA). Expert-level knowledge of Java, Spring Boot, Kafka/Kinesis, and cloud-native patterns (AWS/Azure). 5+ years practicing within SAFe and familiarity with frameworks such as TOGAF, BizBok, and DAMA/DMBok. Strong leadership skills with the ability to mentor senior engineers and influence executive stakeholders through clear, actionable technical blueprints. #J-18808-Ljbffr Veriipro
