Product Engineer Jobs

Introducing Moonlake, AI for creating world simulations. Moonlake is building the frontier of interactive world models: systems that generate, simulate, and reason over 3D environments for embodied AI, robotics and gaming. We develop the simulation infrastructure to build worlds (e.g., assets, scenes, digital twins) at scale. Our team sits at the intersection of: Embodied AI, Robotics simulation, Interactive 3D worlds, World models, Real-time generation, AI infrastructure. Moonlake is building the next generation of AI infrastructure for interactive digital worlds. Our mission is to enable anyone to create, simulate, and interact with rich environments using natural language and multimodal inputs, turning simple ideas into worlds with structure, logic, and agents that can perceive and act. Our team has raised $28M in seed funding from NVIDIA Ventures, Threshold Ventures, AIX ventures and notable angels including Naval Ravikant and Jeff Dean to build the foundational layer for the future of AI - powering everything from creative tools and games to robotics training, simulations, and digital twins. Our goal is to make building and experimenting with these environments as accessible and scalable as publishing video on the internet. We are looking for exceptional research engineers and applied researchers to help push the frontier of interactive AI. We're looking for a Product Engineer who combines strong full-stack engineering with sharp product judgment and a bias for shipping. We want someone who can: Own a product surface end-to-end — not a ticket queue. Turn a rough idea into a shipped, measured feature. Build full-stack, front to back (React / Next.js / TypeScript + Python). Make product decisions without waiting for a PM. Ship fast and iterate on real usage. Moonlake is building tools that sit between: AI systems and human creativity. Simulation and interaction. Research infrastructure and product experience. The interface layer is critical. These products must make highly complex systems feel intuitive, responsive, and powerful. You’ll help define how people interact with the next generation of world-building and embodied AI tools.
