We are looking for a Full Stack / Java Developer to join our backend engineering team building secure, high-performance financial services infrastructure. This is a hands-on engineering role — you will design, code, and optimize core banking systems, payment processing, acquiring flows, and crypto transaction services. The ideal candidate is a pure developer and technology engineer, passionate about writing clean, scalable code and solving complex technical problems.

Key Responsibilities

• Design and implement Java-based microservices using Spring Boot and Hibernate/JPA.

• Develop secure RESTful APIs for payments, wallets, and account management.

• Engineer fault-tolerant, idempotent transaction systems with full audit trails.

• Implement and optimize high-volume, low-latency transaction workflows.

• Apply best practices in security (OAuth2, JWT, TLS, PCI-DSS compliance).

• Integrate with payment networks, banking APIs, and crypto custody solutions.

• Write unit, integration, and load tests to ensure production-grade quality.

• Participate in architecture discussions while contributing actively to code development.

• Support CI/CD, monitoring, and incident response as part of an engineering-driven culture.

Required Skills & Experience

• 5+ years of professional backend development in Java (8 or above).

• Deep expertise in Spring Boot, Hibernate/JPA, and RDBMS (PostgreSQL, MySQL, or Oracle).

• Strong background in financial services systems (core banking, payments, settlement, reconciliation).

• Mastery of transaction integrity, concurrency, and distributed systems design.

• Hands-on experience with messaging queues / event streaming (Kafka, RabbitMQ).

• Proficiency in secure coding standards and financial-grade authentication.

• Solid skills in Docker, Kubernetes, CI/CD pipelines, and Git.

Preferred Qualifications

• Experience with card acquiring, ISO 8583 / ISO 20022, or payment gateways.

• Exposure to cryptocurrency transaction flows, custody, and blockchain APIs.

• Familiarity with NoSQL databases (Redis, MongoDB) and caching strategies.

• Experience with fraud detection and AML/KYC-related systems.
