Context :

We're hiring a Senior Java Architect / Principal Engineer to help design and build a new in-house FX Back Office Book of Record platform, a strategic, resilient system of record for the full post-trade lifecycle of FX transactions, replacing legacy infrastructure at a major Global Markets Technology organization.

We're looking for someone who has already helped design, build, or significantly re-engineer a proprietary FX post-trade / back-office platform inside a bank or financial institution, and who can speak fluently to both the engineering and the FX operations side.

Your Role :

• Define the target architecture for a new strategic FX Back Office / Book of Record platform
• Design scalable, resilient, auditable Java services covering the full FX trade lifecycle: capture, validation, amendments, confirmations/matching, SSI management, CLS & non-CLS settlement, payments, netting, reconciliation, exception management
• Build service-oriented / microservices architectures with event-driven, asynchronous workflows (Kafka or equivalent)
• Integrate with front-office platforms, market/reference data, payments, SWIFT, CLS, GL/accounting, risk, and regulatory reporting
• Stay hands-on in the codebase while setting architectural standards for transaction integrity, idempotency, and recovery
• Mentor senior engineers and help drive engineering best practices

What We’re Looking For :

• 10+ years in software engineering, ideally in Capital Markets
• Expert-level Java, with deep experience in distributed, transaction-processing systems
• Proven experience architecting or building a proprietary/in-house FX post-trade, xhqgsiq back-office, or Book of Record platform
• Strong grasp of FX transaction lifecycles (Spot, Forward, Swap, and/or NDF)
• Experience with post-trade processes: confirmations, settlements, payments, netting, reconciliation
• Exposure to CLS settlement and/or FX payment infrastructure; SWIFT or financial messaging standards
• Strong relational database and transactional data modeling skills
• Comfortable working directly with FX Ops, BAs, and Product Owners, architecture chops without losing the hands-on edge

Nice to have :

Spring/Spring Boot, Kafka, REST/microservices, Oracle/PostgreSQL, Kubernetes, cloud platforms, CI/CD, ISO 20022, legacy-to-strategic platform migration experience.
