We are seeking an experienced Java API Developer to join our Digital Asset development team. This is a hands-on engineering role responsible for building and operating secure, resilient API services that power institutional digital asset capabilities—spanning digital custody, tokenization enablement, digital transfer agency, and digital cash/settlement workflows. You will work closely with cross-functional teams to build robust, scalable, and secure digital asset products that meet our business and technical requirements.
Role Description:
- Design, develop, and maintain Java backend services and REST APIs that support digital asset product flows (custody, tokenization, TA, digital cash/settlement) and integrate cleanly into the broader platform.
- Build API services that participate in the platform’s centralized integration approach—supporting client/app onboarding and app-to-service integrations via an Integration Hub and secure gateways.
- Implement APIs that align to enterprise API design/security/publishing requirements, ensuring designs are review-ready and compliant with internal standards (security, documentation, and platform requirements).
- Partner with product, architecture, and security stakeholders to implement policy-aware integration patterns.
- Contribute to digital asset data patterns, including standardized interfaces and integration points such as Digital Data Interface and Digital Event Stream concepts where applicable for downstream reporting/analytics and operational workflows.
- Build and maintain automated tests (unit/integration) and ensure strong quality gates for services supporting regulated digital asset processing.
- Support production readiness: observability (logs/metrics), incident triage, performance tuning, and resilience improvements for APIs operating in a regulated, high-availability environment.
- Collaborate across teams to drive clear API contracts and dependencies for integrations to traditional platforms (e.g., custody/cash/fund accounting) as part of a hybrid digital + traditional operating model.
Core/Must have skills:
- Strong experience building Java backend APIs (REST) in financial services, ideally including digital assets or closely related domains (custody, cash, fund services, or regulated platforms).
- Hands-on expertise with Spring Boot and common Spring components used for API services (web, security, data access).
- Hands-on experience deploying and operating containerized Java microservices on Kubernetes (e.g., AKS), including working knowledge of core concepts such as Deployments, Services, Secrets, resource requests/limits, and basic troubleshooting in clustered environments.
- Experience working with relational databases (e.g., Oracle) and ORM/data access patterns.
- Proven ability to design and implement API contracts with strong discipline around versioning, backward compatibility, and documentation, aligned to internal API Development Standards.
- Strong understanding of security-first API engineering in regulated environments (authentication/authorization patterns, secure integration paths, least privilege mindset).
- Experience delivering production-grade services with strong engineering practices (code reviews, automated testing, operational readiness).
- Experience working effectively with multi-location engineering teams.
Good to have skills:
- Experience building services that integrate with digital asset platform components such as tokenization, wallet management, smart contract management, or custody-related workflows.
- Familiarity with integration models that span traditional and digital, including standards-based messaging approaches and hybrid architectures used to connect platforms.
- Exposure to event/data distribution patterns for digital assets (e.g., event streams and data interfaces that feed reporting/analytics/monitoring).
- Understanding of digital asset ecosystem concepts (permissioned vs permissionless connectivity; third-party DLT providers; secure key infrastructure/HSM adjacency at a platform level).
- Exposure to Node.js for front-end support or lightweight backend-for-frontend (BFF) services, including working with REST APIs and understanding how Node.js services integrate with enterprise Java or platform backends.
