  • Create comprehensive unit tests and integration tests for SDK components
  • Work directly with game studios during onboarding, implementing agreed-upon features
  • Debug networking issues in customer projects
  • Collaborate with customers to design and implement scalable multiplayer architectures
  • Provide technical guidance on best practices for integrating our technology
  • Occasionally embed with customer teams for extended implementation periods
  • Write clean, maintainable, and well-documented C++ code
  • Implement advanced networking features (latency compensation, state synchronization, prediction)
  • Optimize memory usage and performance for various platform targets
  • Contribute to architectural decisions for client-side implementations
  • Collaborate with Developer Relations team to ensure comprehensive SDK documentation and understand common implementation challenges
  • Work with Product and Engineering teams to align SDK features with platform capabilities

Requirements:

  • 5+ years of experience with C++ development in game development contexts
  • Strong experience with Unreal Engine C++ development
  • Deep understanding of network programming concepts (TCP/UDP, client-server architecture, latency compensation, state synchronization)
  • Experience building multiplayer games and/or multiplayer netcode
  • Proven ability to debug complex technical issues in production environments
  • Strong understanding of memory management and performance optimization in C++
  • Experience working with SDKs or client libraries
  • Excellent problem-solving skills and attention to detail
  • Ability to work independently and manage multiple priorities

Nice to have:

  • Experience with other game engines (Unity) and languages (C#, Go, Lua, TypeScript)
  • Understanding of backend game services and server architecture
  • Experience with WebSockets, gRPC, or other modern networking protocols
  • Knowledge of authentication protocols and security best practices in multiplayer games
  • Experience in Professional Services or customer-facing engineering roles
  • Experience with cross-platform development (PC, console, mobile)
What we offer:
  • Competitive salary (we don't use remote as an excuse to pay less)
  • Unlimited vacation policy. Plus we require you to take at least 2 weeks off each year (and observe local holidays)
  • At least yearly company all-hands and getaways
  • Pick your own equipment. We recommend Macs, but we don't worry if you choose something else!
  • Work with a loving team that treats everyone as family
