The right profile should be comfortable writing substantial Java business logic, while also understanding how applications interact through Kafka-based asynchronous and event-driven architectures.
This is not a pure DevOps role.
The position involves hands-on software engineering and the development of business logic using Java, rather than focusing primarily on infrastructure management, CI/CD pipelines, or platform operations.
At the same time, this is more than a traditional Backend Java role.
The focus goes beyond standard REST/CRUD applications, with a strong emphasis on event-driven architectures, real-time data processing, Kafka-based integrations, and cloud-native solutions running on AWS.
The ideal candidate has a strong Java engineering background combined with practical experience designing and implementing solutions using Apache Kafka.
Experience with Confluent Kafka / Confluent Platform is highly desirable but not mandatory.
What You'll Be DoingDesign, develop, and maintain Java-based applications and services supporting data-driven business processes
Build and evolve event-driven and real-time data streaming architectures using Apache Kafka
Develop Kafka producers, consumers, event-processing components, and integration services
Design reliable and scalable communication patterns between distributed systems
Build cloud-native solutions and deploy/integrate applications within AWS environments
Implement business logic around asynchronous events and streaming data
Ensure solutions are scalable, resilient, maintainable, and production-ready
Troubleshoot application, integration, and data-streaming issues across distributed environments
Contribute to technical design and architectural discussions around Java, Kafka, AWS, and event-driven systems
Collaborate with software engineers, architects, DevOps/cloud engineers, and other technical stakeholders
Apply software engineering best practices, including automated testing, code reviews, observability, and CI/CD
What you'll bring alongBSc/MSc in Computer Science or related field
Minimum 6-8+ years of experience
Strong hands-on experience with Java and modern Java development
Solid experience with Apache Kafka in production environments
Good understanding of: Kafka producers and consumers; topics and partitions; consumer groups and offsets; event-driven architecture; asynchronous processing; failure handling and resiliency
Experience designing xysqume or developing distributed, event-driven systems
Practical experience with AWS and cloud-based application environments
Experience developing APIs and integration services
Good understanding of microservices and distributed application architectures
Experience with automated testing, Git, CI/CD, and modern software engineering practices
Strong analytical and problem-solving skills
Nice to Have:
Experience with Confluent Kafka / Confluent Platform
Experience with Kafka Streams
Experience with Schema Registry and Avro or similar serialization approaches
Experience with AWS services commonly used within event-driven/cloud-native architectures
Infrastructure-as-Code experience, such as Terraform
Containerization and orchestration experience with Docker and Kubernetes
Knowledge of monitoring and observability for distributed systems
