Principal UX Designer

Role Overview

• Lead the end-to-end design of AI-powered experiences across multiple product lines, including agentic workflows, generative interactions, and human-in-the-loop systems
• Define and evangelize UX strategy across complex problem spaces, setting design direction that influences product roadmaps and strategic priorities
• Serve as a thought leader in the design of useful, usable, and desirable AI-powered products in a team environment
• Chart a course for yourself and others in ambiguous situations, leading strategic thinking across teams and mentoring designers
• Contribute to and shape internal design standards for AI patterns, design guidelines, evaluation criteria, and UX quality benchmarks
• Translate model behaviors, data inputs, and system limitations into coherent UX patterns that drive user trust and product adoption at scale
• Prototype with real AI/LLM models to evaluate user prompts, improve model responses, and inform product direction
• Map and design collaboration patterns between users and AI – defining when AI acts autonomously, when humans take control, and how handoffs occur
• Create clear interaction flows that incorporate transparency moments, safety guardrails, override options, and recovery states
• Partner with data science and engineering to shape model requirements, evaluate performance constraints, and align system behaviors with user needs
• Champion responsible AI principles including transparency, fairness, bias mitigation, and user empowerment across all design work
• Collaborate and work cross-functionally with design, program, engineering, data science, and product teams from design concept to design solution, setting UX guidelines and creating assets to ensure bar-raising quality all the way to market
• Present your solutions to design, product, engineering, and senior leadership. Synthesize and manage feedback to incorporate changes appropriately, and iterate the vision and design accordingly
• Communicate design decisions with clarity, influence senior stakeholders, and guide teams through ambiguous or evolving problem spaces
• Work strategically with executives and team members across the organization to drive alignment on complex, cross-organizational initiatives
• Develop use cases and high-level requirements while defining UX strategy and creating user-centered designs utilizing customer feedback, market analysis, and usability findings
• Partner with UX Research to run usability testing and AI-specific validation studies to understand user mental models, trust factors, and interaction expectations
• Leverage qualitative and quantitative data to run evaluative studies for AI features (e.g., prompt/response quality, hallucination risk, trust signals)
• Continually iterate and evolve the way we design and learn from our customers
• Demonstrate deep systems-thinking skills and comfort designing across multiple layers: UI, data inputs, model constraints, and operational workflows
• Mentor and coach designers across the organization, elevating design craft and strategic thinking
• Model best practices in design process, critique, and collaboration
• Identify opportunities to improve design operations, tools, and processes that benefit the broader design organization
• Leverage AI tooling and internal content standards to deliver clear, concise, brand-aligned product experiences
• Design accessible solutions and collaborate with the Accessibility team to ensure WCAG compliance, using AI checks alongside expert review

Requirements

• Extensive design experience creating simple solutions for complex challenges
• Experience designing with AI or LLM technologies, including prompt design, generative UX, and evaluating model output quality
• Strong portfolio of work that illustrates your process, your level of craft, and the measurable results you have driven, with demonstrated end-to-end ownership of complex workflows
• Deep understanding of model behaviors and limitations—hallucinations, confidence levels, deterministic vs. probabilistic output, and data quality impacts
• Experience working across teams to synthesize feedback and input from product management, engineering, data science, and marketing
• Strong interaction design skills with the ability to simplify ambiguous AI behaviors into predictable, user-centered experiences
• Ability to prototype using tools such as v0, Figma Make, Cursor, Python notebooks, model sandboxes, or no-code AI orchestration tools
• Hands-on experience planning and executing end-to-end user research—defining objectives, recruiting participants, moderating studies, synthesizing insights, and translating findings into roadmap and design decisions
• Familiarity with Agile development methodologies in high-velocity, cross-functional teams
• Confidence working in strong, passionate, fast-paced team environments
• Strong time-management, multi-tasking, and prioritization skills
• Critical thinking and problem-solving skills
• Excellent verbal communication and presentation skills that include experience presenting and influencing senior leadership.
