About this opportunity:

We are looking for a Senior Backend Developer (Java) to design, build, and operate scalable backend services and APIs. The role is primarily backend-focused (Java, Spring Boot, microservices, REST) with full-stack exposure (JavaScript/TypeScript frameworks) considered a strong plus for end-to-end delivery and collaboration.

What you will do:

  • Design & develop REST APIs using Java and Spring Boot — ensuring security, backward compatibility, and strong API contracts.
  • Architect microservices applying patterns around service boundaries, resiliency, observability, and secure service-to-service communication.
  • Implement robust OOP principles, clean code practices, and maintainable design patterns.
  • Optimize for performance — leverage multithreading and concurrency to tune services for production-grade throughput and latency.
  • Ensure quality through high-coverage unit testing (JUnit), peer code reviews, and thorough documentation.
  • Containerize and deploy applications using Docker, Kubernetes, and Helm following cloud-native best practices.
  • Collaborate via Git/GitLab and contribute to CI/CD pipelines to enable fast, reliable delivery.
  • Work in Agile teams — partner with Product, QA, and engineering peers to own delivery from development through production support.
  • Contribute to event-driven integrations with Apache Kafka / Confluent Kafka where applicable.
  • Drive a product engineering mindset — contribute with emphasis on maintainability, scalability, and user-impact; participate in design discussions and continuous improvement.
  • Support front-end needs when required, contributing to Angular (preferred) or React-based UIs for end-to-end delivery

The skills you bring:

Must Have:

  • 2–4 years of backend development experience; B.E / B.Tech or equivalent.
  • Deep hands-on expertise in Java & Spring Boot — REST API design and microservices development.
  • Strong understanding of microservices architecture, API versioning, and secure integration patterns.
  • Solid unit testing practices using JUnit with meaningful coverage.
  • Proficiency with Docker, Kubernetes, and Helm for cloud-native deployments.
  • Experience with Git / GitLab and Agile/Scrum delivery practices.
  • Familiarity with Linux/Unix based environments.
  • Hands-on knowledge of multithreading and concurrency in Java.

Good to Have:

  • Experience with Apache Kafka / Confluent Kafka for event-driven integrations.
  • Front-end exposure — Angular (preferred), React, or TypeScript/JavaScript frameworks.
  • GitLab CI/CD pipeline development experience.
  • Exposure to Python and/or C++.
  • Experience with cloud-native architecture and open-source contributions.
