Java Back-end Developer (LATAM)

Job Description

A Java Back-end Developer focuses on building robust, secure, and highly-available server-side systems and APIs that power products, working closely with front-end engineers and architects to ensure performance benchmarks are consistently met.

What We Expect From You:

• Design and implement microservices and distributed systems using Java and the Spring ecosystem, following established architectural patterns.
• Develop secure, high-performance RESTful APIs that are consumed reliably by both web and mobile client applications.
• Model, optimise, and manage relational and NoSQL databases to support scalable, data-intensive workloads.
• Implement authentication and authorisation mechanisms using OAuth2, JWT, and Spring Security best practices.
• Identify and resolve performance bottlenecks through profiling, load testing, and targeted refactoring of critical code paths.
• Integrate third-party services, payment gateways, and external APIs in a maintainable and testable way.
• Write comprehensive unit and integration tests to maintain high coverage and prevent regressions across services.

Requirements

• 3+ years of professional Java back-end development with deep knowledge of the JVM and core Java libraries.
• Strong hands-on experience with Spring Boot, Spring Cloud, and ORM frameworks such as Hibernate or JPA.
• Solid understanding of microservices architecture, including service discovery, load balancing, and inter-service communication.
• Experience with relational databases (PostgreSQL, MySQL) and caching solutions like Redis.
• Practical knowledge of message brokers such as Kafka or RabbitMQ for building event-driven services.
• Comfortable with Docker, Kubernetes, and setting up or maintaining CI/CD pipelines in cloud environments.
• Proficiency in English.
