Role Summary :

We are seeking a Java API Developer to join our Digital Asset development team. This is a hands-on software engineering role responsible for designing, developing, testing, and supporting RESTful APIs and backend services in a financial services environment. The role contributes to building reliable, secure, and well-documented services that integrate with upstream/downstream systems and support business-critical 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-based backend services and REST APIs that support financial services workflows and data use cases.
  • Implement APIs in line with internal requirements for API design, security, versioning, and documentation, ensuring solutions are consistent and reusable.
  • Collaborate with business and technology stakeholders to understand requirements, clarify edge cases, and deliver well-scoped API changes in an Agile sprint model.
  • Write automated tests (unit and integration), participate in peer code reviews, and contribute to quality gates for each release.
  • Support service troubleshooting and production readiness activities such as logging, monitoring, defect triage, and minor performance tuning with guidance from senior team members.
  • Maintain clear technical documentation for APIs and integrations (e.g., endpoints, payloads, dependencies, and operational notes).

Core/Must have skills :

  • Hands-on experience developing Java backend applications, including REST API development in production or near-production environments.
  • Familiarity with common Java API frameworks and patterns (e.g., Spring Boot / Spring MVC-style services) and building maintainable service layers.
  • Understanding of secure API fundamentals (authentication/authorization concepts, safe handling of sensitive data) and willingness to follow enterprise standards.
  • Strong grasp of SDLC basics: source control, code reviews, automated testing, and working in Agile delivery.
  • Experience working in financial services (or another regulated environment) where reliability, controls, and documentation matter.

Good to have skills :

  • Awareness of internal enterprise API governance and onboarding concepts (e.g., role of enterprise teams and standards in API publication and compliance).
  • Experience with tools commonly used in enterprise Java teams (e.g., Maven/Jira-style workflows) and basic observability practices.
  • Digital asset knowledge: familiarity with concepts such as custody, tokenization, wallets, or blockchain-adjacent workflows—enough to understand domain terminology and integration needs.
  • Exposure to API integration patterns with third parties and documentation for API consumers.
