A1 is building a proactive AI smart assistant for everyday users to bring intelligence to conversations, errands, organizing and workflows. 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 design the detailed mechanics of how users interact with A1 – the gestures, states, flows, and micro-decisions that determine whether an AI-driven product feels controlled or confusing. This role is focused on HCI interaction design: how users give input, receive feedback, supervise AI actions, correct mistakes, and maintain agency over AI-driven workflows. There are no established playbooks for interaction design in proactive AI products. You will help define new patterns from the ground up.
What You’ll Be Doing
- Design detailed interaction models for AI-driven flows, including how users initiate, monitor, pause, correct, and complete multi-step tasks.
- Define interaction states for AI interfaces: idle, thinking, acting, waiting, uncertain, interrupted, failed, and recovered.
- Design human-in-the-loop controls – how users review AI decisions, override actions, and stay informed without micromanaging.
- Create interaction patterns for delegation, approval, correction, escalation, reversibility, and recovery.
- Create detailed interaction specifications, annotated flows, and prototypes for engineering handoff.
- Work with product and ML teams to translate system capabilities and constraints into usable interaction patterns.
- Test interaction designs with real users to identify where AI behavior creates confusion, distrust, or friction.
- Contribute to a shared library of HCI interaction patterns that can be reused across the product.
What You Will Need
- Experience as an interaction designer or senior UX designer with strong interaction design depth.
- Ability to design at the micro level – states, transitions, edge cases, and failure handling.
- Strong prototyping skills in Figma or equivalent tools.
- Systematic thinking – able to map complex AI behavior into coherent user‑facing interaction logic.
- Clear understanding of HCI principles: user control, transparency, feedback, and graceful recovery.
- Experience working closely with engineers to ensure interactions are implemented as designed.
- Comfort designing for systems where output is non‑deterministic and behavior can vary across sessions.
- Strong judgment on when users should be guided, interrupted, asked for confirmation, or left alone.
