Senior System Architect

Sr. System ArchitectThe Sr. System Architect serves as the Technical Design Authority responsible for bridging the gap between Enterprise Architecture strategy and engineering delivery. This role is not just about high-level roadmaps; it is a "boots-on-the-ground" leadership position that defines the detailed technical blueprints—including microservices design, cloud-native patterns, and API contracts—required to modernize mission-critical Rail Transportation systems. You will lead the "Strangler" migration of legacy IBM Mainframe/TPF environments into a state-of-the-art Java and Spring-based event-driven architecture (EDA), ensuring that architectural integrity is maintained throughout the full engineering lifecycle.Key ResponsibilitiesConceptual-to-Technical Bridge: Act as the primary translator between EA strategy and engineering. Convert high-level business capabilities into detailed technical specifications for microservices, integration patterns, and cloud-native architectures.Modernization Leadership: Lead the technical design and execution for replacing legacy Rail Transportation systems (Mainframe/TPF) with modern, scalable Java and Spring Boot microservices.API & Integration Strategy: Design and govern robust API contracts and integration patterns to facilitate seamless, real-time communication across heterogeneous, multi-domain environments.Engineering Oversight: Maintain deep visibility into the full engineering lifecycle. Partner directly with development teams to ensure implementation adheres to architectural standards for reusability, scalability, and performance.Framework Implementation: Ground all application and system designs in industry-standard frameworks, including TOGAF, BizBok, and DAMA (DMBok), ensuring alignment with enterprise data and business standards.Agile Governance: Provide technical leadership within a Scaled Agile Framework (SAFe) environment, aligning the "Architectural Runway" with Program Increment (PI) planning and continuous delivery.Minimum QualificationsExperience: 15+ years of progressive IT experience, with at least 10 years of dedicated technology/system architecture experience.Domain Expertise: Required experience defining and implementing technology solutions for rail transportation or large-scale logistics companies.Technical Mastery: Proven 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).Frameworks & Certifications: 5+ years of active experience practicing within SAFe. Working knowledge of TOGAF, BizBok, and DMBok.Leadership: Demonstrated ability to mentor senior engineers and influence C-level stakeholders through clear, technical blueprints.
