User Experience Designer III, AI at Work

We are looking for a Senior UX Designer to be the single-threaded owner (STO) of the user experience for a brand-new AI-native application launching to both Amazon internal customers and external AWS customers. This is a high-impact, high-autonomy role on a small, fast-moving team where you will be the voice of the customer and the primary driver of design quality. You will own the experience from concept through production — ensuring that what we build is not only functional, but genuinely loved by the people who use it. This product is AI and agent-native from the ground up — not a bolt-on AI feature to an existing service. You will define what it means to interact with intelligent agents, design trust and transparency into AI-driven workflows, and create experiences that make complex AI capabilities feel intuitive and empowering for enterprise customers. You will be the single designer responsible for the end-to-end experience — from first-run onboarding through daily power-user workflows — across both internal Amazon users and external AWS customers. This is not a role where you'll receive a fully scoped brief and execute against it. You'll operate in ambiguity, define the problem space, and chart the design direction. You'll wear many hats — researcher, interaction designer, visual designer, prototyper, and storyteller — and you'll thrive doing it. Key job responsibilities - Lead end-to-end design from problem framing and discovery through delivery, iteration, and post-launch refinement, ensuring solutions address real customer needs across complex product surfaces. - Establish and maintain interaction and visual design standards that ensure coherence across multiple product areas, creating patterns that are maintainable and scalable over time. - Collaborate with product managers, engineers, and data scientists to align cross-functional partners around a shared design direction, balancing customer needs against technical constraints and business priorities. - Conduct and apply user research to inform design decisions, map full customer journeys to identify friction and opportunities, and use data signals to validate and iterate on shipped experiences. - Evaluate when and how to integrate generative AI tools into the design workflow, accelerating prototyping and exploration while maintaining high craft standards where human judgment is essential. A day in the life You might start your morning reviewing research findings with your team, then move into a design critique where you present interaction concepts for a complex workflow spanning multiple systems. After lunch, you could partner with engineering to work through edge cases and technical constraints, followed by a strategy session where you advocate for a design direction with product leadership. Throughout it all, you are mentoring other designers, shaping how the team approaches problems, and pushing for solutions that serve customers over the long term. About the team Our team is focused on creating meaningful, intuitive experiences that customers rely on. We operate in a collaborative environment where designers, product managers, engineers, and researchers work closely together to solve problems that span multiple systems and touchpoints. We value clarity of thought, inclusive perspectives, and a commitment to craft. As we look ahead, we are investing in new ways to leverage AI capabilities and scale our design impact. This is an opportunity to shape both what we build and how we build it.
