Full job description

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.
