Full Stack Java Developer

Role Description

• Design, develop, and maintain full‑stack features spanning Java backend services and modern web UI components for digital asset products and operational tooling.
• Build and evolve REST APIs and service integrations that support digital asset workflows and participate in the platform’s centralized integration approach (e.g., integration hubs / secure gateways).
• Develop responsive, maintainable front‑end experiences using modern frameworks (e.g., React / Vue / Angular), focusing on usability for financial services users and operational personas.
• Collaborate with cross‑functional teams to translate business requirements into well-defined technical designs, estimates, and incremental deliveries within an Agile environment
• Implement robust automated testing practices across the stack (unit, integration, and UI/API tests) and uphold strong quality gates through code reviews and CI/CD discipline.
• Contribute to operational readiness: logging/monitoring, performance tuning, production support, and reliability improvements for client- and operations-facing digital asset services.
• Work with security and platform stakeholders to ensure solutions meet the expectations of regulated financial services environments (secure-by-design, least privilege, auditability).

Core/Must have skills

• Strong, hands-on experience delivering full‑stack applications in financial services (or similarly regulated environments), with clear ownership from UI through backend services.
• Advanced proficiency in Java and modern backend development using Spring Boot and common Spring modules (web, security, data).
• Strong experience building RESTful APIs and microservice-style backend services, including documentation and integration patterns.
• Solid experience with a modern front-end framework such as React, Vue.js, or Angular, including building production user interfaces.
• experience working with relational databases (e.g., Oracle) and ORM/data access patterns
• Strong engineering practices: automated testing, code reviews, and iterative delivery in an Agile team environment.
• experience with enterprise cloud and delivery tooling (CI/CD pipelines, containerization), and operating microservices in modern platforms.
• experience working effectively with multi-location engineering teams.
