Conversation Designer

About the Role

A1 is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior.
You will shape how users experience AI from the ground up. This is an early, high-ownership role where your design decisions will directly influence core user flows, interaction models, and product direction.
You will design systems and journeys – how users discover value, interact with intelligence, and build trust in an AI-driven product.

What Youll Be Doing

• Design conversational experiences across chat, voice, and AI assistant interactions.
• Create natural, intuitive dialogue flows that help users accomplish tasks efficiently.
• Develop prompts, assistant behaviors, fallback patterns, and interaction logic for AI systems.
• Work closely with product, engineering, and ML teams to shape how the assistant communicates, responds, and guides users.
• Prototype and iterate on conversational patterns, onboarding flows, memory/context handling, and multi-step interactions.
• Define tone, personality, and response principles across different user scenarios and product surfaces.
• Analyze user behavior, conversation failures, and edge cases to improve assistant quality and reliability.
• Help establish scalable conversation design standards, libraries, and best practices across A1 products.
• Balance user experience, model limitations, latency, and product constraints when designing interactions.

What You Will Need

• Experience in conversation design, UX writing, product design, interaction design, or related fields.
• Strong understanding of conversational UX for chatbots, voice assistants, or AI-powered products.
• Ability to design clear multi-turn interactions, assistant flows, prompts, and error recovery patterns.
• Strong communication and systems thinking - able to simplify complex AI capabilities into intuitive user experiences.
• Experience collaborating closely with engineers, product teams, and AI/ML teams in fast-moving environments.
• Comfort working with ambiguity, evolving product directions, and rapid iteration cycles.
• Strong attention to language, tone, clarity, and interaction details.
• Ability to think deeply about user intent, context, memory, and conversational behavior over time.
• Willingness to take ownership from early exploration through shipped product experiences.

Nice to have

• Experience designing AI-powered or data-heavy products.
• Familiarity with usability testing and qualitative research methods.
• Experience working on zero-to-one products or early-stage teams.
• Interest in emerging UX patterns for AI, automation, or intelligent systems.

Outcomes

• Own the end-to-end AI interaction experience, from first discovery to repeated use.
• Ensure AI behaviors are predictable, intuitive, and trusted by users.
• Take responsibility for the clarity, usability, and effectiveness of complex workflows.
• Detect friction or confusion proactively and design solutions that prevent issues before they reach users.
• Own the translation of research and engineering capabilities into coherent, usable product experiences.
• Define and track success metrics for AI UX, and iterate designs based on real user behavior.
• Mentor and influence other designers and cross-functional teams on AI interaction standards.
• Make high-impact design decisions that balance speed, technical feasibility, and long-term system quality.
• Drive a design philosophy that becomes a foundation for all future AI product surfaces.

How We Work

The best products today in the world were built by small, world-class teams. We are a high talent density and hands-on team. We make decisions collectively, move at rapid speed, striking a balance between shipping high-quality work and learning. Joining our team requires the ability to bring structure, exercise judgment, and execute independently. Our goal is to put in the hands of our users a truly magical product.

Interview process

If there appears to be a fit, well reach to schedule 3, but no more than 4 interviews. Applications are evaluated by our technical team members. Interviews will be conducted via virtual meetings and/or onsite. We value transparency and efficiency, so expect a prompt decision. If youve demonstrated the exceptional skills and mindset were looking for, well extend an offer to join us. This isnt just a job offer; its an invitation to be part of a team thats bringing AI to have practical benefits to billions globally.
