Were looking for a Java Backend Developer who has built and operated production-ready, scalable, distributed systems and enjoys solving backend challenges: performance, reliability, scaling, data stores, data modeling, and failure handling. This role goes beyond CRUD - expect Kafka workflows, microservices, strong engineering hygiene (including testing, observability, and clean design), and experience with architectural patterns of large, high-scale data applications.

Java 17+ | Spring Boot | Microservices | Kafka | Postgres/MySQL/MongoDB | AWS

• Own backend services/features end-to-end: design, implement, test, release, and operate.
• Build robust Kafka producers/consumers and handle real failure scenarios (retries, rebalancing, lag).
• Design APIs with backward compatibility, performance, and clear contracts.
• Optimize databases (indexes, query plans, schema trade-offs) and improve service latency.
• Establish quality: code reviews, tests by default (JUnit/Mockito/Integration), and engineering standards.
• Strengthen observability and debugging using logs/metrics; drive RCA and preventive fixes.
  

• Java 17+ with strong fundamentals + applied problem-solving
• Production-grade concurrency
• Kafka in production, including client resilience best practices (retries/timeouts, handling rebalances)
• Microservices and distributed systems exposure (trade-offs, failure modes)
• Database performance tuning (SQL and/or MongoDB)
• AWS working knowledge (EC2/RDS/S3/IAM/Lambda/SNS/SQS/ECS)
• Docker, K8s
  

gRPC, Virtual Threads, Caching Mechanism, OpenSearch, Kibana/Grafana, FluentBit, AWS Services(Lambda, SNS, SQS, ECS, EKS), MQTT, FCM, strong observability setups.

• Owns services/features end-to-end and improves reliability/performance measurably
• Builds/strengthens flows with a clear retry/idempotency strategy
