  • Troubleshoot and resolve complex technical issues in production and staging environments.

Required Skills

  • 10+ years of backend development experience, with deep expertise in Java (Java 8 or later).
  • Strong hands-on experience with Spring Framework (Spring Boot, Spring Data, Spring Security, etc.).
  • Solid understanding of microservices architecture, API design, and integration patterns.
  • Experience with SQL databases (e.g., PostgreSQL, MySQL) and NoSQL stores (e.g., MongoDB, Redis).
  • Proficient in RESTful API design and implementation.
  • Hands-on experience with unit testing (JUnit, Mockito) and CI/CD pipelines.
  • Experience working with Docker, and familiarity with container orchestration platforms like Kubernetes.
  • Good understanding of application security principles, including authentication (OAuth2, JWT), authorization, and encryption.
  • Familiarity with message brokers (Kafka, RabbitMQ) and asynchronous processing.
  • Excellent problem-solving, analytical, and communication skills.

Preferred Skills

  • Experience with cloud platforms (AWS, GCP, or Azure).
  • Familiarity with GraphQL or gRPC.
