OneXtel Limited is seeking a Backend-Focused Full-Stack Developer for our Pune office. This role is ideal for experienced engineers with a strong background in designing, building, and scaling high-performance microservices.

• Develop resilient backend services with Java and Spring Boot in a microservices architecture.
• Build secure, scalable RESTful APIs with robust authentication and authorization.
• Create and manage message-driven, event-based, and asynchronous systems using queues or streaming platforms.
• Implement caching strategies (e.g., Redis, Memcached) to optimize performance and scalability.
• Write optimized and secure SQL queries for relational databases like PostgreSQL, MySQL, or Oracle.
• Ensure high code quality through comprehensive unit, integration, and contract testing (e.g., JUnit, Mockito).
• Contribute to CI/CD pipelines, automated deployments, and overall production readiness.
• Deploy, manage, and troubleshoot applications in Kubernetes-based environments.
• Collaborate effectively with frontend, DevOps, and QA teams to deliver end-to-end features.
• Participate actively in architecture discussions, design reviews, and performance tuning.
