Job Description

Posted on: January 3, 2026

A1 is a self-funded AI group, operating in full stealth. We’re building a new global consumer AI application focused on an important but underexplored use case. As a Product Designer at A1, you will shape how users experience AI - turning complex technology into intuitive, human-centered products. This is an early, high-ownership role where your design decisions will influence core user flows, interaction models, and product direction from day one. You won’t just design screens. You’ll design systems and journeys: how users discover value, interact with intelligence, and build trust in an AI-driven product. Working closely with product, engineering, and AI teams, you’ll help bring frontier technology to life through thoughtful, usable design. Why This Role Matters

  • You will design the core user experiences of A1’s first AI products - shaping how people interact with intelligent systems in ways that feel intuitive, trustworthy, and genuinely useful.
  • This is not a redesign or iteration role. You are helping define entirely new interaction paradigms for AI-driven products, translating complex capabilities into simple, human-centered experiences.
  • Your work will directly influence how our products are understood, adopted, and loved by users around the world.

What You’ll Do

  • Lead end-to-end design for one or more AI product surfaces, from early concept to production
  • Design key user flows that make advanced AI capabilities feel simple, natural, and usable
  • Partner closely with product, engineering, and AI teams to explore problems, test ideas, and ship fast
  • Create wireframes, user flows, prototypes, and high-fidelity UI for web and mobile
  • Rapidly prototype and iterate on new interaction models, especially for AI-driven experiences
  • Conduct usability testing and synthesize insights to refine product direction
  • Help define and evolve A1’s design system to support speed, consistency, and scalability
  • Advocate relentlessly for the user while balancing product velocity and technical constraints

You’ll Thrive Here If You…

  • Enjoy designing in ambiguous, zero-to-one problem spaces
  • Are excited by AI products and curious about how humans interact with intelligent systems
  • Can simplify complex workflows into clear, elegant user experiences
  • Move fast, test early, and iterate without over-polishing
  • Take strong ownership - from problem definition to shipped solution
  • Are comfortable collaborating with highly technical teammates

Requirements

  • 3+ years of experience as a product/UX designer, with a portfolio spanning web and mobile products
  • Strong proficiency in Figma and rapid prototyping tools
  • Solid understanding of interaction design, layout, hierarchy, and visual systems
  • Experience working closely with engineers and product managers in fast-moving teams
  • Comfort designing from incomplete inputs and evolving requirements

Nice to Have

  • Experience designing AI-powered or data-heavy products
  • Familiarity with usability testing and qualitative research methods
  • Experience working in early-stage products or startup environments
  • Interest in emerging UX patterns for AI, automation, or intelligent systems

What You’ll Get

  • High ownership and autonomy from day one - you own core product experiences, not just screens
  • Founding-level influence on product design and UX direction
  • Remote-first flexibility
  • High-impact scope - your designs shape the core user experience of a global consumer AI product
  • Competitive compensation with performance-based bonuses
  • Backed by a profitable US$2B group, with the speed and focus of a startup
  • Insurance coverage, flexible time off, and global travel insurance
  • The opportunity to build a new AI product from zero, defining how users interact with intelligent systems
  • A small, senior, high-performance team where you work directly with founders and influence major product decisions

Our Team & Culture We operate as a dense, senior, high-performance team. We value clarity, speed, craftsmanship, and relentless ownership. We behave like founders — we build, ship, iterate, and hold ourselves to a high technical bar. If you value excellence, enjoy building real systems, and want to be part of a small team creating something globally impactful, you’ll thrive here. About A1 A1 is a self-funded, independent AI group backed by BJAK, focused on building a new consumer AI product with global impact. We’re assembling a small, elite team of ML and engineering builders who want to work on meaningful, high-impact problems.
