Lead AI Engineer, Game Generation

The game-generation pipeline is the product. Every game in the feed comes out of it: creator's prompt, intent extraction, template matching, model routing, asset retrieval, generation, validation and repair, runtime, and play telemetry back into the loop. It is built around a fixed library of approximately 20 proven core mechanics with hard-constraint specs and a quality score fed by real play data, such as completion, replay, and share/remix.

Role Responsibilities:
- Own the full generation pipeline end to end.
- Move playability pass rate up and cost per generation down at volume.
- Run benchmark suites, LLM-as-judge, and playability pass/fail checks.
- Show output quality improving over time.
- Own the economics including tiered model routing, RAG/templates, caching, and small-model distillation.
- Remain hands-on in the runtime, specifically with browser/JS games, procedural content, and asset/image generation.
- Collaborate with core engineering in Sofia and with game design.
- Serve as the technical owner of the pipeline and lead the team.

Qualifications:
- Have shipped text-to-game or AI game-creation technology similar to Rosebud, Bitmagic, Astrocade, Websim, Roblox Cube/Assistant, or Hidden Door.
- Have shipped a prompt-to-running-app agent at scale similar to Replit Agent, Lovable, Bolt, or v0.
- Understand the full generation loop including generation, validation, repair, and evaluation using benchmark suites.
- Demonstrate expertise in generation economics including tiered model routing, RAG/templates, caching, and small-model distillation.
- Proven track record of cutting cost per generation by 10x.
- Strong engineering skills in the runtime environment including Three.js, Phaser, Babylon, voxel engines, procedural content, and asset/image generation.

Nice to Have:
- Research credentials in generative game technology such as DeepMind Genie/SIMA or Microsoft Muse.
- Experience leading a team of 2-3 people.
- Experience fine-tuning or distilling open models in production.
- Image or 3D asset generation experience.
- Game-engine background with Unity or Godot.
- Startup or founding-team experience.
