What you’ll work on
You will design, develop, debug, and enhance backend services handling transactional and high-volume workloads. The role involves building scalable Java services, integrating with internal and external systems, improving system reliability, and solving production issues involving concurrency, transactions, latency, and failures.

Strong understanding of Collections, Exception Handling, Multithreading and Concurrency
Hands-on experience with Spring Boot, Spring MVC and REST APIs
Experience developing Microservices
Production experience with at least one messaging technology such as Kafka, RabbitMQ, JMS, SQS or equivalent

JMS / MQ
SAST / DAST tools
Experience with payment, banking, lending, transaction-processing, travel-tech or other high-volume transactional platforms
Who will fit well
We are particularly interested in engineers who have personally built and supported backend systems in production, rather than candidates whose experience is primarily frontend or basic CRUD development.
You should be comfortable explaining real examples of:
Concurrency or asynchronous processing
Messaging/event-driven systems
Transaction failures and retries
Database locking or data consistency
Production performance issues
Debugging critical backend incidents
Screening Criteria
Applicants should ideally have:
3–6 years of relevant Java backend experience
Production experience with Java + Spring Boot + Microservices
Hands-on exposure to messaging/event-driven processing
Hands-on exposure to multithreading/concurrency
Experience with transaction-sensitive backend systems
Ability to work from office in Noida
