Descripción de la vacante

Luxoft is hiring a Senior Java Integration Developer in Abu Dhabi to architect and implement a cloud-agnostic, event-driven Portable Domain Integration API Layer. You will design and deploy resilient Saga workflows using Apache Camel and Spring WebFlux, perform content-based routing, and manage distributed state with PostgreSQL and Redis.

The role emphasizes Kubernetes-based deployment, observability, and scalable, non-blocking endpoints.

Formación

• 8–12 years of experience with Java 17, Spring Boot, and Apache Camel.
• Experience with API gateways (Kong, Apigee, Mulesoft, WSO2) and OpenAPI.
• Strong knowledge of Kubernetes, Redis, PostgreSQL, RabbitMQ and Kafka.

Descripción del empleo

We are looking for a Senior Java Integration Developer with deep expertise in distributed systems, Enterprise Integration Patterns (EIP), and reactive architectures to build our next-generation Portable Domain Integration API Layer.

Responsibilities

• In this role you will be responsible for coding, wiring, and deploying a cloud-agnostic event-driven orchestration layer using Spring Boot, WebFlux, and Apache Camel.
• You will build resilient stateful Saga workflows that aggregate downstream APIs, handle mixed synchronous and asynchronous communications, enforce distributed concurrency locks, and scale dynamically inside Kubernetes.

Core Application Development

Build low-latency non-blocking REST endpoints using Spring Boot and Spring WebFlux Netty to handle high-concurrency client requests without thread starvation.

Workflow amp Saga Orchestration

Implement centralized Saga Orchestration routes using Apache Camel DSL to manage complex multi-step transaction lifecycles. Write explicit compensating actions, undo blocks, to ensure eventual data consistency.

Content-Based Routing

Develop data-driven micro-routing logic EIP that dynamically evaluates upstream JSON XML responses at runtime to route or bypass conditional steps.

State amp Concurrency Management

Integrate state tracking in PostgreSQL and build Idempotent Consumer patterns using Redis Sentinel clusters with strict WAIT locking blocks to prevent race conditions across scaled containers.

Asynchronous Webhook Handling

Build non-blocking callback endpoints that receive external notifications, re-acquire transaction state using global correlation IDs and finalize parked workflows.

Containerization amp Deployment

Write multi-stage immutable Dockerfiles and generic Kubernetes manifests Deployment StatefulSet ConfigMaps Secrets that run identically across Azure AKS AWS EKS and On-Premises environments.

Observability amp Autoscaling

Embed OpenTelemetry distributed tracing interceptors W3C context into code and configure KEDA Kubernetes Event-driven Autoscaling rules mapped to queue depths RabbitMQ Kafka for scale-to-zero capabilities.
