Joe Schwartz
Senior AI Game Engineer
Gameplay, full stack systems, runtime AI, and production tooling for teams that want Generative AI integrated into both the player experience and the development process.
What I Do
I build full stack game systems: moment-to-moment gameplay, server architecture, runtime content generation, editor tooling, and Generative AI pipelines that turn production bottlenecks into playable workflows.
Best Fit
Senior remote roles or contracts where I can own hard systems independently, collaborate cleanly with teams, and connect engine code, gameplay, AI tools, backend services, and production UI into shipped game features.
Engine + Gameplay
AI + Generation
Full Stack
Experience
Shipping games end to end.
Gameplay systems, engine work, frontend and backend delivery, runtime AI characters, and Generative AI tooling built for playable releases and production teams.
Senior AI / Gameplay / Full Stack Engineer, Upheaval AI
Contract work spanning Unreal shader plugin planning, Unity mobile runtime downloading and caching, tutorial and trial-mode fixes, Codex-assisted Unreal and Unity workflows, React frontend work, Azure backend work, and demo music production.
Senior AI Game Engineer, Azra Games
Built a generative social media manager, ported a Python/HTML clicker into a Discord Activity, created Unity quest visualization and map tools, improved quest editor workflows, added save-data tooling, and used AI-assisted debugging to move production tools quickly.
Senior AI Game Engineer, Running Bull
Led a two-engineer effort to deliver an MVP XR shooter in Unity, integrated the game with a Next.js/React/TypeScript frontend and Django backend, and built an OpenAI-powered real-time voice agent with memory and web chat UI.
Senior AI / Gameplay / Full Stack Engineer, Upheaval AI
Built Unreal and Unity integrations backed by a custom C# stack for generated game data, images, 3D models, rigged characters, animation-ready assets, runtime NPC behavior, RAG knowledge systems, API layers, and serverless image-generation infrastructure.
Senior Game Engineer (Full Stack), Tempo Storm
Created AI-assisted playable card pipelines, deterministic client-side combat simulation, shared C# DLL systems, and event-driven gameplay architecture for Early Access shipping.
C++ Game Engineer, Infinite Games
Developed UE4/UE5 HTTP plugins, backend features, MySQL infrastructure support, C# automation tools, Blazor admin surfaces, logging, Swagger APIs, and Azure deployment workflows.
System Engineer, UW Computer Aided Engineering
Automated Windows deployment, SCCM task sequences, VMware server builds, App-V packages, lab-scale software management, and technical troubleshooting for 700+ machines.
Selected Work
Playable AI systems, tools, worlds, and music.
Unreal Engine MMO
Solo MMO prototype work covering C++ motion-matching character systems, efficient server backend architecture, replicated multiplayer, remote user testing, procedural open-world terrain, generated-world preview maps, right-click teleporting, and an LLM chat interface for procedural settings.
Also includes an asset-generation pipeline that creates 2D art from prompts, converts it to 3D, rigs humanoids, imports assets, and spawns them in runtime and editor workflows.
Runtime AI Characters
Generated game data, models, rigs, and behavior so playable agents and NPCs could be created and driven at runtime.
LLM NPC Memory and Control
Built NPCs with generated data, memory, thoughts, conversations, decision loops, and an interpretive layer for creating and controlling other agents.
AI Tools
Built in-game tools for modifying 3D models at runtime by editing generated images and regenerating meshes from the result.
AI-Generated Music
Created and published AI-generated radio-style songs using prompt-driven composition and production workflows.
Choose Your Own Adventure
Built a Unity app using OpenAI text generation to support guided genres, freeform choices, and branching narrative play.
Contact
Remote senior game engineering.
Best conversations for me are remote-only roles or contracts shipping games and prototypes where AI systems meet engine work: gameplay systems, runtime generation, NPCs, agent workflows, backend integrations, full stack tools, and production-ready prototypes.
