Full Job Description

đź“‹ Description

  • • Build and prototype AI-native product interfaces across web and mobile platforms, focusing on interaction patterns that do not yet have established conventions.
  • • Create functional prototypes of new HCI interaction models including streaming responses, multi-step task flows, real-time feedback loops, and system state visibility for AI-driven experiences.
  • • Translate design concepts into working code with high attention to usability, responsiveness, motion, and performance in AI interfaces.
  • • Experiment with UI patterns that clearly communicate progress, uncertainty, confidence, failure, and recovery to users interacting with AI systems.
  • • Design interfaces that enable users to supervise, correct, and redirect AI behavior without requiring micromanagement of system operations.
  • • Collaborate closely with product, design, and machine learning teams to rapidly validate interaction ideas through iterative prototyping and testing.
  • • Contribute to frontend architecture and develop reusable UI components specifically tailored for AI product surfaces.
  • • Identify, diagnose, and resolve usability, performance, and state management issues unique to AI-driven interfaces.
  • • Work at the intersection of design and engineering, bridging gaps between ambiguous design concepts and executable code without formal handoffs.
  • • Prototype rapidly in environments with incomplete specifications, prioritizing user clarity and functional integrity over rigid adherence to predefined specs.
  • • Maintain a strong focus on human-computer interaction principles, ensuring AI behavior is understandable, controllable, and useful in real-world workflows.
  • • Apply deep understanding of animation, frontend architecture, and UI performance to create seamless, responsive experiences across devices.
  • • Demonstrate strong product and UX instincts by identifying when interfaces are unclear, confusing, or broken from the user’s perspective.
  • • Operate independently with high judgment, bringing structure and execution to fast-moving, high-talent-density teams focused on shipping magical AI experiences.

🎯 Requirements

  • • Strong frontend engineering skills in React, TypeScript, or equivalent
  • • Experience building interaction-heavy or experimental interfaces
  • • Strong product and UX instincts — ability to identify unclear or broken user experiences
  • • Ability to prototype rapidly in ambiguous environments with incomplete specs
  • • Understanding of animation, responsiveness, frontend architecture, and UI performance
  • • Interest in HCI interfaces and designing for trust, control, transparency, and recovery

🏖️ Benefits

  • • Work with a high-talent-density, hands-on team building AI products for global impact
  • • Collaborate directly with product, design, and ML teams in a fast-moving, decision-making environment
  • • Opportunity to shape foundational AI interaction patterns with no existing industry conventions
  • • Transparent and efficient interview process with prompt decisions and direct team involvement
