• 1+ years of experience in distributed systems.
• Understanding of system architecture approaches.
• Strong foundation in object-oriented design.
• Strong data structure, logic, and algorithm skills.

Nice-to-Have Skills

• Familiarity with professional software engineering principles and best practices across the entire development lifecycle.

• You’ll work on high-performance infrastructure services that support tens of thousands of concurrent players, solving challenges in scalability and efficiency.
