Job DescriptionNavy Federal Credit Union currently does not provide sponsorship for this role. Applicants must be authorized to work in the United States without the need for current or future sponsorship.The Application Engineer, Core Banking Modernization will provide support to technical leadership for the design, implementation, certification, and evolution of the capabilities required to operate NFCU's legacy and modern banking platforms as one logical banking ecosystem. The role will support the engineering of the Core Banking Platform, with focus on dual-core coexistence. This role partners closely with business, product, architecture, engineering, and transformation teams to translate strategic objectives into scalable, secure, and resilient technology solutions.
The Application Engineer provides technical expertise in core banking platforms, system integration, cloud-native architectures, DevSecOps, and modernization methodologies. This role will support the implementation and delivery of our Core Banking modernization program with a specific focus on co-existence of on premise and cloud banking platforms as an enabler for complete migration to a new core banking platform.
Responsibilities- Support the technical design and implementation for dual-core coexistence across banking platforms
- Provide support for the solution/application design for implementing the Core Banking modernization program's coexistence (on premise and cloud) model and data migration/integration strategy
- Support definition of the complete transaction lifecycle from originating channel through transport, ingestion, validation, decomposition, state resolution, routing, core processing, reconciliation, settlement, accounting, and General Ledger outcomes.
- Develops the integration design patterns for dual core routing (validate, enrich ,locate, route) inbound data to banking applications from internal and external platforms utilizing APIs, messaging services, event-driven architectures, and microservices
- Provide support for managing the mechanics of the cloud core platform with focus on data processing and reconciliation
- Develops the integration design patterns for data egress from core banking platform to other internal and external platforms utilizing APIs, messaging services, event-driven architectures, and microservices
- Support engineering of routing patterns for single-core, cross-core, split-post, shadow, replay, migration, and fallback scenarios for banking transactions
- Support definition of engineering controls that preserve transaction atomicity, ordering, idempotency, balance integrity, posting completeness, and financial finality across both cores
- Support the adoption of AI-enabled software engineering capabilities, including intelligent code generation, test case creation, impact analysis, and documentation generation.
- Support the design of AI-driven observability and operational intelligence capabilities to proactively detect anomalies, identify root causes, and improve platform resiliency.
- Design repeatable migration patterns covering data migration, synchronization, validation, cutover, rollback, stabilization, and legacy retirement
- Provide support to establish development standards, coding practices, security controls, and quality gates for modernization initiatives.
- Collaborate with infrastructure, security, and operations teams to implement end-to-end operational readiness and monitoring capabilities.
- Facilitate technical workshops, design sessions, architecture reviews, and modernization planning activities.
- Research and evaluate emerging technologies relevant to core banking and financial services modernization.
Qualifications- Bachelor's Degree in Computer Science, Information Technology, Engineering, or related discipline, or equivalent combination of education and experience.
- 7+ years of software engineering, solution architecture, and enterprise technology experience in Core Banking domain.
- Advanced knowledge of Core Banking platforms (e.g. Fiserv, FIS, Oracle, etc.) .
- Experience in intersection of Core Banking with Retail Banking, Payments, Lending, or Products and Pricing (e.g.Zafin) environments
- Experience designing and delivering large-scale modernization and transformation initiatives migrating from mainframe systems to SaaS application.
- Understanding of data migration strategies from mainframe to cloud applications.
Desired Qualifications - Experience working within highly regulated environments (e.g, NCUA)
- Knowledge of security, compliance, resiliency, and operational excellence principles.
- Hands-on experience with cloud-native architectures, distributed systems, API platforms (e.g. Mulesoft), event-driven solutions (e.g.Apache Kafka), and enterprise integrations patterns.
