BackEnd Java Developer

We are seeking a Backend Developer to design and deliver cloud‐native, event‐driven microservices using Java, Spring Boot, and Kafka. You will model robust relational data structures, implement EDA patterns (Event Sourcing/CQRS), and contribute to business process automation with BPMN/Camunda. You'll champion architecture best practices, CI/CD automation, and high quality standards across the SDLC.

Key Responsibilities

• Design & Development Build secure, resilient microservices with Java, Spring, Spring Boot.
• Implement event‐driven integrations using Kafka (producers/consumers, schemas, retries, DLQs).
• Apply Event Sourcing and CQRS where appropriate.
• Design and optimize relational database schemas (transactions, indexing, performance).
• Architecture & Quality Apply architecture best practices and patterns (e.g., hexagonal/clean architecture, DDD concepts, idempotency, circuit breakers).
• Produce application designs and BPMN models; maintain clear technical documentation.
• Ensure quality through unit/integration/contract testing, code reviews, and performance tuning.
• Automation & Operations Build and maintain DevOps/CI/CD pipelines (build, test, deploy, release).
• Contribute to observability (structured logging, metrics, tracing) and operational reliability.
• Process Automation Analyze business processes and implement Camunda workflows (BPMN/DMN), integrating with services and events.

• Practical experience with Event‐Driven Architecture, Event Sourcing, CQRS.
• Design & Modelling Strong application design skills.
• Good knowledge of modelling tools/standards (BPMN).
• Data Proficient with Relational DBMS (schema design, SQL, ACID transactions, performance optimization).
• Graph databases knowledge is a plus (e.g., Neo4j).
• Delivery & DevOps Good knowledge of DevOps pipelines/CI‐CD and automated testing.
• Integration Knowledge of interoperability technologies: REST/gRPC web services, message‐oriented middleware, service bus/ESB, event architecture.
• Soft Skills Rapid self‐starter with excellent interpersonal and communication skills.
• Delegation and decision‐making skills.
• Strong writing (redaction) skills and ability to give technical presentations.
• Ability to apply high quality standards and adapt to fast‐changing technologies.
