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.
You will sit at the intersection of design and engineering, building the AI interfaces that users actually interact with. This is not a UI maintenance role. You will prototype, test, and ship new interaction patterns for AI-driven experiences where established conventions do not yet exist. This role is focused on HCI - building interfaces that make AI behaviour understandable, controllable, and useful in real workflows.
Responsibilities- Build and prototype AI-native product interfaces across web and mobile.
- Create functional prototypes of new HCI interaction models, including streaming responses, multi-step task flows, real-time feedback loops, and system state visibility.
- Translate design concepts into working code with high attention to usability, responsiveness, and motion.
- Experiment with UI patterns that show progress, uncertainty, confidence, failure, and recovery clearly to users.
- Build interfaces that let users supervise, correct, and redirect AI behaviour without micromanaging the system.
- Work closely with product, design, and ML teams to validate interaction ideas quickly.
- Contribute to frontend architecture and reusable UI components for AI product surfaces.
- Identify and fix usability, performance, and state management issues in AI-driven interfaces.
- Strong frontend engineering skills in React, TypeScript, or equivalent.
- Experience building interaction-heavy or experimental interfaces.
- Strong product and UX instincts - you can tell when something is unclear or broken from a user's perspective.
- Ability to prototype rapidly in ambiguous environments with incomplete specs.
- Understanding of animation, responsiveness, frontend architecture, and UI performance.
- Interest in HCI interfaces and how to design for trust, control, transparency, and recovery.
- Comfort working at the boundary of design and engineering without clear handoffs.
- Ability to move fast while keeping the user experience clear and usable.
