On any given day at TGC, you might:

• Design and implement large-scale, highly available backend microservices that serve millions of concurrent players. Aim for zero downtime.
• Monitor system health and quickly respond to any failures or glitches to deliver a smooth online experience to players worldwide.
• Improve quality through code reviews, expanded test coverage, technical post-mortems, improved documentation.
• Encourage collaboration and domain knowledge sharing; reducing bus factor is a feature.
• Work and iterate very closely with members of our (distributed, remote) Gameplay, Engine, and Ops teams.
• Design testable, flexible features & systems that can withstand frequent changes to functional and performance requirements (this is a live game with a lot of new content, nothing is static!)

Must have:

• 8+ years experience working on the back-end for an MMO or high-volume, distributed, low-latency web services (relaxed slightly for Senior level).
• Fluency in both a functional language such as Erlang/Elixir and a multi-paradigm language such as Go. You realize languages are just tools and you are already fluent in at least these two types. (relaxed slightly for Senior level).
• Have strong opinions on the different approaches to managing network communication, resource scaling, automated deployment, security, reliability, and data tracking/analysis
• Be familiar with (and have passion for) creating unit tests, stress tests, and integration tests. We are behind the curve with automated testing and aim to get ahead of it.
• Be proficient with Linux, container-native development, CI/CD, GitOps, and debugging in network environments.
• Have a thorough understanding of the tradeoffs involved in building highly available, at-scale backend systems, caching strategies, and distributed systems.

Nice to have:

• (Shareable) hobby projects relevant to the role, eg: a game engine, a networking app, a multiplayer game using an existing engine.
• Experience with Kubernetes, Helm, and Docker.
• Experience with UDP, bit-level serialization, delta compression, and other techniques for developing efficient network code for real time games
• Our custom game engine is written in C++; the more familiarity you have with performant C++, the better.
