Principal Backend Engineer (Live / Game)

Primary: Bay Area (San Francisco / Peninsula)   |   Secondary: NYC

The Opportunity

We're doing an AI-first engineering rebuild for a company that already has an audience of 100M+ people. This is a zero-to-one build with no legacy constraints. You're not joining to babysit existing infrastructure. You're joining to design the real-time backend that absorbs a creator-triggered traffic spike and keeps every player in the game.

The Product

You'll own the backend powering Beast Industries' live and real-time game experiences. Traffic here is spiky and unforgiving: a content drop or a creator event can drive a concurrency surge an order of magnitude beyond normal load, and the system has to hold. That means:

  • 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.

What You'll Do

  • 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 the 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 get other teams to actually adopt and hold to it.
  • Drive the architecture review and RFC process, raising the quality bar across backend engineering.
  • Solve the most complex distributed-systems problems where the textbook patterns don't fully apply.
  • Mentor staff and senior engineers, and represent our engineering practice externally through talks and writing.

Who You Are

  • AI-Native: You're 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: You've owned backend architecture for systems serving large, spike-driven user bases, and you've led the response when one of them broke in production.
  • Direction-Setter: You've set technical direction adopted across multiple teams or titles, not just inside one team.

Depth in backend languages and real-time tech appropriate to live game systems (Go, C++, Rust, Java, or equivalent) and the relevant data/state stores. Bonus points for 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, and contributions to the broader engineering community.

Benefits

  • Equity: Highly competitive equity package designed for a foundational hire.
  • Hybrid Model: Expected ~3 days per week in-office (Bay Area or NYC).

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
