Interaction Designer, HCI

COMPANY

A1 is building a proactive AI smart assistant for everyday users to bring intelligence to conversations, errands, organising 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.

ROLE

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 ...
