This project uses a custom framework and does not use Spring, Spring Boot, Hibernate, or standard web containers.  This is a fantastic opportunity to focus on core Java and system fundamentals.

Critical Skills:

  • Expert knowledge of techniques for data caching
  • Working knowledge of computer networking including TCP/IP sockets, HTTP/1.1, HTTP/2.0,  WebSocket, and SSL or TLS.

Additional Skills:

  • Good understanding of operation of application logic and user interfaces
