About this role
## Member of Technical Staff — Product Engineer ### About Moonlake Moonlake is building the frontier of interactive world models—systems that generate, simulate, and reason over 3D environments for embodied AI, robotics, and gaming. They develop simulation infrastructure to build **worlds at scale**, including assets, scenes, and digital twins. Their mission: enable anyone to **create, simulate, and interact with rich environments** using natural language and multimodal inputs—turning ideas into worlds with structure, logic, and agents that can perceive and act. Moonlake has raised **$28M** in seed funding from NVIDIA Ventures, Threshold Ventures, AIX Ventures, and notable angels including Naval Ravikant and Jeff Dean. ### The Role Moonlake is looking for a **Product Engineer** who combines strong full-stack engineering with sharp product judgment and a bias for shipping. You’ll own a product surface end-to-end (not a ticket queue) and turn rough ideas into shipped, measured features. ### Why This Role Matters As AI systems become more capable, the challenge shifts from only building better models to making capabilities **intuitive, responsive, and effortless** to use. You’ll help define how researchers, developers, and creators interact with the next generation of world-building and embodied AI tools. ### What You’ll Do - Scope fuzzy product goals into **testable, instrumented features** and measure impact - Break down ambiguous work, sequence it, and drive it to production - Collaborate closely with research, engineering, and founders - Use AI-native engineering tools (e.g., **Claude Code, Codex, or similar**) to ship faster - Build full-stack features **front to back** (React / Next.js / TypeScript + Python) - Make product decisions without waiting for a PM ### What We’re Looking For - A track record of **shipping real product** in ambiguous, fast-moving environments - ~**3+ years** building and shipping production web products (focus on demonstrated shipping over years) - Strong full-stack engineering experience with **React, Next.js, TypeScript**, plus solid backend judgment (schemas, architecture, tradeoffs) - High-signal technical communication: turn ambiguity into clear plans, explain tradeoffs to non-engineers, and drive alignment - Strong product/UX judgment: know what’s worth building ### Technical Experience We Value - **React, Next.js, TypeScript, Tailwind, shadcn**, and modern web app architecture - Product features/UI for **agentic systems** (AI takes actions, reasons over state, multi-step long-horizon workflows, streaming + generative interfaces) - Scalable backend services and APIs - AI-native product workflows ### Bonus Points - Experience shipping **agent- or LLM-powered** product features - Founding engineer / 0→1 startup experience - Physics AI, simulation, or robotics stacks (e.g., **Isaac Sim, MuJoCo**) - 3D asset workflows (e.g., **Blender**) or other world-building tools ### Location / Work Style - **On-site, in-person** team currently based in **San Francisco**
