Core Java Developer

Requirements

Our Custody and Investor Services Technology organization is seeking an experienced, versatile Technical Architect to drive platform modernization, technical governance, and forward-engineering initiatives across our global Custody business.

In this flexible, multi-disciplinary role, you will be deployed across critical functional domains within Custody based on evolving program priorities-including Securities Settlements, Asset Servicing (Corporate Actions), Transaction Management, Tax, and Cash & FX Processing. You will act as the principal technical authority and architecture partner within assigned delivery teams, bridging the gap between business product requirements, operational workflows, and engineering execution.

A core strength of the ideal candidate is a solid foundational background in software development (ideally Java and Oracle ecosystems). While you will not be expected to write production code on a day-to-day basis, your deep engineering fluency will enable you to evaluate technical designs, challenge engineering decisions with rigor, build hands-on Proofs of Concept (PoCs) when exploring new technologies, and leverage Generative AI capabilities to accelerate discovery and governance.

2.1 Solution Architecture & Domain Modernization (Flexible Deployment)

2.2 Architecture Governance & Permit to Build (P2B)

3.1 Domain & Capital Markets Knowledge

• Strong track record (10+ years) of relevant experience in the design and development of enterprise-grade Java-based systems.
• 10+ years' hands-on experience in Java 17/21 LTS (Java 21 preferred), Core Java, Jakarta EE (J2EE), Spring Framework 7/Spring Boot 4.x RESTful services.
• Working knowledge of modern Java language features and exposure to JVM internals
• GC tuning and performance profiling.
• Databases
• Oracle or equivalent (PostgreSQL/MySQL) with strong SQL and PL/SQL programming expertise; schema versioning via Flyway/Liquibase.
• Proficient in using AI-assisted development tools such as Claude, GitHub Copilot, Devin, Cursor for code generation, review, and productivity acceleration.
• Experience working across multiple technologies and medium-to-complex distributed systems; well versed with design standards, patterns, and enterprise frameworks.
• Fast learner of new tools, frameworks, and technologies; comfortable working with distributed/cross-timezone teams.
• Experience in event-driven architecture
• Spring Boot components integrating with Apache Kafka and MQ (IBM MQ), including partitioning, consumer groups, idempotency, and transactional outbox patterns.
• Excellent knowledge of Relational Databases, SQL, and ORM technologies (JPA 2/3, Hibernate 6) and connection pooling (HikariCP).
• Strong understanding of Spring Security 6+
• OAuth2.0/OIDC, JWT-based stateless auth, RBAC/ABAC.
• Familiarity with API design
• REST with OpenAPI/Swagger, and exposure to high-performance service communication.
• Resilience patterns using Resilience4j
• circuit breaking, rate limiting, retries.
• Caching and NoSQL exposure
• Redis, MongoDB, Elasticsearch; awareness of vector databases (Pgvector) for AI/RAG-integrated services is a plus.
• Exposure to Spring AI and LLM integration patterns (RAG workflows) is an added advantage.
• Tools
• Well versed with IntelliJ IDEA/Eclipse.
• Test-Driven Development and automated testing: JUnit 5, Mockito, AssertJ, Cucumber/Gherkin, Testcontainers for integration testing, contract testing (WireMock/Spring Cloud Contract); JIRA, Maven/Gradle, SonarQube.
• Experience with version control
• GIT, Bitbucket, GitHub (including PR/branching workflows).
• Experience with Docker, multi-stage builds, Red Hat OpenShift, and Kubernetes (Deployments, ConfigMaps, Secrets, Ingress, HPA/KEDA autoscaling).
• Experience with CI/CD systems such as Jenkins, GitHub Actions, GitLab CI, or ArgoCD.
• Observability exposure
• Micrometer, Prometheus, Grafana, distributed tracing via OpenTelemetry/Zipkin/Jaeger.
• Domain-Agnostic Solution Architecture: Architect and deliver robust,scalable solution designs across various Custody domains asprioritized by the business:
• Settlements & Transaction Management: Real Time trade matching, routing, orchestration, and settlement instruction life cycle.
• Asset Servicing: Corporate actions event processing, notifications, elections, and entitlement calculations.
• Tax Processing: Withholding tax calculations, regulatory reporting integrations, and tax documentation workflows.
• Cash & FX Processing: Liquidity management, payments integration, Real Time cash ledgering, and FX execution.
• Microservices & Event-Driven Patterns: Design modern domain-driven microservices, event-streaming architectures (eg, Kafka, messaging Middleware), and RESTful/OpenAPI integration layers to replace Legacy monolithic and batch-oriented systems.
• Enterprise Data Architecture: Define low-latency, resilient data pipelines and data-sharing integration patterns interfacing with core internal ledgers, market infrastructures (SWIFT, Euroclear, Clearstream, DTCC), and enterprise cloud data platforms (AWS, Snowflake).
• Non-Functional Requirements (NFRs): Define and enforce enterprise standards for high availability, fault tolerance, transaction idempotency, horizontal scalability, disaster recovery, and auditability.
• Permit to Build (P2B) Oversight: Lead the evidence-based Permit to Build (P2B) process for assigned programs and Epics, ensuring full architectural justification, risk mitigation, and compliance with enterprise standards prior to build phases.
• AI-Driven Governance Adoption: Utilize and contribute to modernized, AI-assisted architecture review tools to ensure rapid review turnaround and consistent governance across delivery streams.
• Technical Debt Management: Proactively identify, document, and categorize technical debt at the Epic level, ensuring remediation plans are clearly owned and tracked.
• Third-Party Evaluation & FIT Governance: Support technical evaluations for third-party software products and vendor platforms, conducting structured decision blueprinting (build vs. buy) to ensure architectural fit and financial efficiency.
• 8-12+ years of progressive technology experience within Securities Services, Investment Banking or Capital Markets.
• Deep functional knowledge in at least one (and familiarity with several) core Custody domains:
• Securities Settlements & Clearing
• Asset Servicing/Corporate Actions
