  • Taking ownership of production challenges - troubleshooting, resolving, and protecting the customer experience across environments.
  • Contributing to architectural decisions and maintaining clear documentation to accelerate team performance.
  • Evaluating, testing, and adopting emerging tools and practices that improve performance, scalability, and reliability.

  • Working knowledge of Spring Boot, REST APIs, Microservices, Maven, JPA/Hibernate, JDBC, and unit testing frameworks such as JUnit or TestNG.
  • Preferred: Experience with Docker, Redis, MongoDB, RabbitMQ, or cloud platforms (AWS, GCP, Azure).
  • A solid understanding of system design, database modeling, and service-oriented architecture.
  • Awareness of AI-driven tools and an interest in integrating AI capabilities into application development.
