Full Job Description

đź“‹ Description

  • • Design conversational flows for AI interactions across chat, task completion, and assistant-guided workflows to enable reliable, long-running user interactions.
  • • Define how the AI sets expectations, signals uncertainty, asks for input, and communicates errors or limitations during multi-step tasks.
  • • Develop prompts, response templates, fallback patterns, and assistant behaviors tailored for complex, context-aware workflows with non-deterministic model behavior.
  • • Design user mechanisms to supervise, interrupt, correct, and redirect AI behavior through natural conversation, ensuring user control throughout interactions.
  • • Establish principles for trust and transparency in AI communication without overwhelming users with excessive technical detail or unnecessary explanations.
  • • Collaborate with product, engineering, and machine learning teams to define how the assistant manages ambiguity, memory, and context across sessions.
  • • Analyze conversation logs to identify failure points, misaligned user expectations, and gaps in recovery pathways for AI interactions.
  • • Define and maintain tone, voice, and response principles across diverse user needs and product surfaces, ensuring consistency and clarity.
  • • Build and evolve conversation design standards and pattern libraries to scale best practices across the product ecosystem.
  • • Shape the foundational framework for AI conversation design at a level of reliability and context depth not yet established in the industry.
  • • Focus on long conversation arcs, evolving user intent over time, and memory-aware interactions that support persistent, real-world task completion.
  • • Work in a high-talent-density environment where decisions are made collectively, speed is prioritized, and independent judgment and execution are required.
  • • Contribute to creating a truly magical AI product that delivers practical benefits to billions of users through intuitive, reliable, and human-centered conversation.

🎯 Requirements

  • • Experience in conversation design, UX writing, interaction design, or a related field.
  • • Strong understanding of conversational UX for AI products, chatbots, voice assistants, or assistant-led workflows.
  • • Ability to design multi-turn interactions, including prompting flows, error recovery, clarification, and context handoff.
  • • Clear thinking about how AI systems should communicate trust, limitations, progress, and failure.
  • • Experience collaborating with engineers, product managers, and ML teams.
  • • Comfort working with evolving product requirements and non-deterministic system behavior.

🏖️ Benefits

  • • Opportunity to shape foundational frameworks for AI conversation design at an industry-leading level of reliability and context depth.
  • • Work with a high-talent-density, hands-on team focused on shipping high-quality, magical AI products.
  • • Collaborative decision-making environment with rapid iteration and emphasis on learning through execution.
  • • Direct impact on a product designed to bring practical AI benefits to billions of users globally.
