What you will 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 building world models and embodied AI systems.
• Use AI-native engineering tools to ship faster.

Required qualifications

• Track record of shipping real product in ambiguous, fast-moving environments.
• 3+ years building and shipping production web products.
• Strong full-stack engineering experience with React, Next.js, and TypeScript.
• Solid backend engineering judgment including designing database schemas and system architecture.
• Strong technical communication.
• Sound product and UX judgment.

Nice to have

• Extensive experience building and shipping agent- or LLM-powered product features.
• Founding engineer or 0→1 startup experience.
• Physics AI, simulation, or robotics stacks such as Isaac Sim or MuJoCo.
• 3D asset workflows (Blender) or other world-building and asset creation tools.
