About the Role

This role involves an AI-first engineering rebuild for a company with an audience of over 100M people, focusing on a zero-to-one build without legacy constraints. The Principal Backend Engineer will design the real-time backend to manage creator-triggered traffic spikes and maintain player engagement in live game experiences. This includes owning the backend infrastructure for Beast Industries' live and real-time game experiences, which must handle significant concurrency surges from content drops or creator events.

Responsibilities

Define how live-service backend infrastructure is built, operated, and evolved across every active title.
Design real-time systems (matchmaking, state sync, real-time messaging, leaderboards, in-game economy) that stay correct and fast under spike-driven load.
Set the reliability bar: SLOs, capacity planning, incident response, and resilience patterns for systems under massive consumer load.
Set multi-year backend architecture direction for live game systems, balancing scalability, latency, cost, and reliability.
Be the principal technical advisor to engineering and product leadership on backend strategy and high-stakes technology calls.
Lead the design and review of high-concurrency, low-latency systems where correctness and performance both matter.
Own reliability strategy for spiky, event-driven systems, and ensure other teams adopt and adhere to it.
Drive the architecture review and RFC process, raising the quality bar across backend engineering.
Solve the most complex distributed-systems problems where textbook patterns do not fully apply.
Mentor staff and senior engineers, and represent our engineering practice externally through talks and writing.

Requirements

AI-Native: Already burning through tokens and using AI coding agents daily to move faster.
Distributed-Systems Master: Typically 15+ years building and operating backends at consumer scale, with real depth in real-time or live-service architecture: high concurrency, low latency, eventual consistency, horizontal scaling, fault tolerance.
Battle-Tested at Scale: Owned backend architecture for systems serving large, spike-driven user bases, and led the response when one of them broke in production.
Direction-Setter: Set technical direction adopted across multiple teams or titles, not just inside one team.

Skills

Depth in backend languages and real-time tech appropriate to live game systems (Go, C++, Rust, Java, or equivalent)
Relevant data/state stores
Direct game backend experience (matchmaking, netcode-adjacent services, game state, in-game economies)
Operating through large unpredictable traffic events tied to media or creator moments
Contributions to the broader engineering community
