We are seeking a Senior Java Developer to design, develop, and optimize high-performance backend services for critical enterprise platforms. In this role, you will work with modern Java technologies, reactive programming, and distributed systems to build scalable, resilient, and cloud-ready applications. You will contribute to complex system integrations, technological modernization initiatives, and the continuous evolution of software architecture. Working with technologies such as Spring Boot, Apache Kafka, gRPC, and AWS, you will help deliver reliable solutions that meet demanding performance requirements. You will collaborate with technical teams to improve engineering practices, automated testing, and continuous delivery processes. This opportunity is ideal for a senior engineer who enjoys solving complex architectural challenges and collaborating with international teams in a technically demanding environment.

Design, develop, and maintain distributed backend services using modern Java versions, particularly Java 17 and Java 21, and the Spring Boot framework.

Build reactive and asynchronous applications using technologies such as Project Reactor or RxJava to improve responsiveness, throughput, and resource utilization.

Optimize application performance, scalability, reliability, and resource efficiency across complex distributed environments.

Design and implement service-to-service communication using gRPC and Protocol Buffers (Protobuf).

Develop and maintain event-driven architectures and asynchronous messaging solutions using Apache Kafka.

Leverage AWS cloud services to support the deployment, scalability, and operation of backend applications.

Implement and optimize concurrency and multithreading strategies to support high-throughput processing and efficient resource management.

Develop and maintain automated testing suites using JUnit, Mockito, and AssertJ to ensure code quality and system reliability.

Work with data storage and caching technologies, including Redis, PostgreSQL, and MongoDB, selecting and optimizing solutions according to application requirements.

Contribute to architectural decisions, system integrations, and complex technology modernization initiatives.

Improve CI/CD pipelines and development workflows to support reliable, automated software delivery.

Collaborate with engineering teams to establish development standards, promote best practices, and continuously improve software architecture and engineering processes.
