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.

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
