Creative Technologist, HCI

About A1 There are over 5 billion users using basic applications today such email, notes, tasks that are not AI-native. Our mission is to build a proactive smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows, with minimal prompting. 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. Our objective is to help users complete tasks daily enjoyable with over ~90%* reduced time. Role You will explore and build experimental AI experiences that help define how people interact with proactive AI systems. This role sits at the intersection of design, engineering, and AI experimentation. This is not a research-only role. You will build prototypes, test ideas, and help the team decide which interaction models should become part of the product. What You'll Be Doing Prototype experimental AI interfaces beyond standard chat UI. Build quick proof-of-concept experiences using AI models, APIs, and frontend tools. Explore new ways for users to understand, direct, and collaborate with AI systems. Test interaction ideas around human control, trust, transparency, memory, multimodal input, and long-running workflows. Work with product, design, and ML teams to turn early ideas into testable prototypes quickly. Identify useful HCI patterns from research, products, and emerging tools, then test whether they work for A1. Document experiments clearly - what was tested, what worked, what failed, and what should be built next. Contribute to the team's understanding of what HCI should look and feel like in a real consumer app. What You Will Need Experience prototyping at the intersection of design and technology - creative technology, design engineering, prototyping, or R&D roles. Ability to build functional prototypes using web technologies, APIs, or AI tools. Curiosity about how AI systems work and how users build mental models of AI behavior. Comfort moving between design thinking and hands-on building. Awareness of HCI principles, emerging UI patterns, and the limitations of current AI systems. Strong communication skills - able to explain experimental ideas and prototype findings clearly. High comfort with ambiguity and early-stage product exploration. Good judgment on which experiments are interesting versus which ones are actually useful for users. 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.
