  • You have solid knowledge of C/C++ programming.
  • You understand key multiplayer technology concepts like firewall traversal, data compression, encryption, distributed algorithms, latency compensation, and more.
  • You are comfortable working within large, existing codebases and integrating new technologies.
  • While mentorship experience is a plus, you're eager to grow your skills and collaborate with more senior programmers.
