Staff AI Designer

About the role

Staff AI Product Designer to shape what AI does, how it behaves, and how it fits into real user workflows. This role sits at the intersection of product, design, and machine learning—turning emerging capabilities into reliable, high-quality user experiences. You'll design systems: behaviors, decisions, orchestration, and end-to-end experiences powered by AI.

What you'll do

• Identify and pattern match high-value opportunities for AI across the product; define what AI should do and what it should not do
• Architect AI-driven workflows and agentic systems that operate across real-world scenarios and over time, including multi-step and agent-to-agent interactions
• Establish decision frameworks: when systems should act, ask, escalate, or defer
• Design for uncertainty, failures, and edge cases as core system behavior
• Design experiences for users who are increasingly managing AI systems and agents; ensure AI integrates into real user workflows
• Define what "good" looks like (e.g. trust, accuracy, effort reduction) and design evaluation scenarios and feedback loops
• Act as a bridge between AI research, technical capabilities, and user needs
• Prototype and run focused experiments that isolate variables and generate clear insights

What you'll need

• Strong product judgment—you consistently make high-quality calls on what to build and why
• Experience working on zero-to-one products and comfort operating through ambiguity and rapid change
• Deep understanding of LLMs and their limitations, along with grounding in traditional ML approaches
• Experience defining design principles, heuristics, or evaluation criteria for AI systems
• High standards for quality, with a track record of identifying where AI systems break down in real-world use
• A scientific mindset—you can design experiments that isolate variables and produce meaningful insights
• Systems thinker: you're happier designing behaviors and flows than polishing interfaces

What they offer

• Competitive salary, annual bonus and equity
• Regular compensation reviews
• Unlimited access to Claude Code and best-in-class AI tools
• Generous paid time off above statutory minimum
• Hybrid working with MacBooks standard
• Employee events for employees, friends, and family
