We support your professional development with comprehensive training programs and sponsor various industry events like DevConf and GDG. Join us and push the boundaries of what’s possible, while taking your career to new heights!

We are seeking a Senior Java Developer with deep expertise in reactive programming and event-driven architectures. You will be responsible for designing and building highly scalable, non-blocking backend services using Vert.x, Spring WebFlux, MongoDB, and cloud native technologies.

You will play a key role in architecting production-grade microservices, developing reactive APIs, driving engineering best practices, and mentoring development teams on modern asynchronous design patterns.

Job requirements

Role and Responsibilities:

  • Design and develop reactive backend services using Java, Vert.x, and Spring WebFlux

  • Build highly scalable, non-blocking applications that support large transaction volumes and real-time processing

  • Implement asynchronous workflows using reactive streams, futures, event-driven messaging, and parallel execution patterns

  • Design and maintain REST APIs using OpenAPI specifications and contract-first development principles

  • Develop event-driven solutions leveraging messaging technologies such as Kafka, JMS, or AMQP

  • Collaborate with frontend teams, integrating APIs with React, Angular, Vue, and TypeScript applications

  • Design and implement cloud native microservices deployed on AWS Kubernetes environments using Docker and Helm

  • Implement resilience patterns, including retries, circuit breakers, fault tolerance, and graceful degradation

  • Ensure solutions meet production standards for observability, monitoring, logging, tracing, and supportability

  • Promote clean architecture, test automation, code quality, and Agile engineering practices

Technical Knowledge

Reactive Java Development

  • 10+ years of enterprise software development experience

  • Strong Java development experience

  • Experience building distributed microservices and API driven applications

  • Experience with reactive, asynchronous, or event-driven systems

  • Experience with modern backend frameworks such as Vert.x, Spring Boot, Spring WebFlux, Micronaut, Quarkus, or similar technologies

  • Experience with MongoDB, NoSQL, and/or relational databases

  • Experience with AWS or other major cloud platforms

  • Experience with Docker, Kubernetes, Helm, and CI/CD pipelines

  • Strong understanding of software design patterns, clean architecture, and secure coding practices

  • Experience with automated testing using frameworks such as JUnit and Mockito

What We're Looking For

The ideal candidate demonstrates:

  • Deep understanding of reactive programming and parallel execution patterns

  • Experience building production-ready microservices with comprehensive error handling

  • Strong API design and integration experience

  • Clean, maintainable, layered architecture with clear separation of concerns

  • Strong automated testing discipline and code quality standards

  • Experience with observability, monitoring, and operational support in production environments

What Success Looks Like

The ideal candidate will demonstrate:

  • Strong understanding of reactive system design rather than traditional synchronous Spring applications

  • Experience building production ready cloud native services

  • Ability to design scalable event-driven solutions

  • Excellent testing discipline and quality engineering practices

  • Experience implementing observability, monitoring, and operational support capabilities

  • Clean architectural thinking with strong separation of concerns
