UX Engineer

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 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 You'll Be Doing

• Build and prototype new AI-native product experiences across web, mobile, and experimental interfaces.

• Turn early product ideas, interaction concepts, and conversational flows into functional prototypes quickly.

• Work closely with product, design, engineering, and ML teams to explore and validate new interaction models.

• Develop high-quality frontend experiences with strong attention to usability, motion, responsiveness, and polish.

• Experiment with AI-driven UI patterns, multimodal interactions, streaming interfaces, and real-time assistant experiences.

• Bridge design and engineering by translating product concepts directly into working code and interactive prototypes.

• Iterate rapidly based on product feedback, technical constraints, and user behavior.

• Help shape frontend architecture, reusable UI systems, and prototyping workflows for fast experimentation.

• Contribute to the overall product experience, balancing usability, speed, technical feasibility, and AI limitations.

What You Will Need

• Strong frontend engineering skills with experience building modern web or mobile applications.

• Strong product and UX instincts with the ability to think beyond implementation details.

• Experience building prototypes, interaction-heavy interfaces, or experimental product experiences.

• Proficiency in modern frontend technologies such as React, TypeScript, SwiftUI, Flutter, or similar frameworks.

• Ability to rapidly prototype ideas and iterate quickly in ambiguous, fast-moving environments.

• Good understanding of interaction design, animation, responsiveness, and UI performance.

• Interest in AI-native interfaces, conversational products, multimodal interactions, and emerging UX patterns.

• Comfortable working closely with designers, product managers, and ML engineers.

• Ability to balance engineering quality with experimentation speed and product iteration.

• Willingness to take ownership from concept exploration through production implementation.

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 hands of our users a truly magical product

Interview process

If there appears to be a fit, we'll 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 you've demonstrated the exceptional skills and mindset we're looking for, we'll extend an offer to join us. This isn't just a job offer; it's an invitation to be part of a team that's bringing AI to have practical benefits to billions globally.
