Founding Game Systems Engineer (Social Gaming)

Location: San Francisco (preferred) / Hybrid / Remote

Type: Founding-level role (equity + cash upon pre-seed closing)

InZone is a social gaming platform built around AI, persistent 3D avatars, and live shared worlds. We’ve grown to 200K+ users through creator-led distribution and are now focused on tightening the core multiplayer game systems that will drive retention, referrals, and real product-market-fit.

We are early.

We are pre-magic.

And we’re looking to build this properly with the right person for the long haul. This is not about shipping standalone titles. This is about architecting lightweight, socially dense multiplayer loops that integrate directly into a live world environment and turn a product into a network.

You will:

• Design repeatable 2–4 player game loops that drive invites and social return behavior
• Implement mechanics directly in Unity (or equivalent engine)
• Build systems that integrate with avatars, chat, AI characters, and feed infrastructure
• Instrument and iterate based on retention metrics (D1/D7/D30, referrals per user, social engagement deltas)
• Help define the core “game spine” of the platform

You should have:

• Experience shipping multiplayer or social game systems
• Strong systems thinking (retention loops, progression, replayability)
• Unity experience and ability to implement mechanics directly
• Comfort operating in early-stage ambiguity
• A bias toward iteration and measurable impact

Nice to have:

• Previously founded or co-founded a startup
• Experience fundraising or working closely with investors
• Based in San Francisco
• Background in consumer social, multiplayer gaming, or youth platforms

We are looking to improve online social interactions for the better. We need someone who wants to build something enduring, not just take on a short-term contract.

If you’re excited about engineering social density and shaping the foundation of a social gaming platform from its early stages, let’s talk.
