Head of AI, Game Generation - Text - TO - Game Pipeline

This is a role that TechTree is recruiting for on behalf of one of our clients. TechTree is an AI-driven recruitment platform working with high-growth companies. When you apply, our AI Agent matches you not just to this role, but to other relevant opportunities across our network, so one application can unlock multiple roles. Head of AI, Game Generation — lead the team and architecture behind a text-to-game pipeline running at volume. London, remote-first. Our client is a venture-backed startup running a mobile feed made entirely of short, AI-generated browser games created from a prompt. The generation pipeline is the product. You'll lead the AI team that builds and runs it and own its design end to end: architecture, roadmap and evaluation strategy. This is a leadership and system-design role, not day-to-day production coding. What You'll Do → Lead the AI team (ML/data engineering, game development, a contracted engineering partner) and grow it as the company scales → Own the generation pipeline architecture, from intent extraction and model routing to validation, repair and runtime → Define quality measurement (benchmarks, LLM-as-judge, playability checks) and design the loop that feeds play data back into generation → Own the economics: model routing, templates and retrieval, caching, and when to distil or fine-tune What We're Looking For → Have led a team that shipped an LLM-powered generation system to production at real volume → Have designed multi-stage generation systems with evaluation built in, and cut cost per generation while holding quality → Technical enough to hold your own in architecture and code reviews, and to prototype when needed → Games experience is highly recommended: shipped games, worked at a studio, or built game tooling or content systems £120,000–£150,000 gross per year plus equity. Full-time, London-based, remote-first and moving to hybrid. We're unable to sponsor UK visas at present. What is TechTree?
