Define AI capabilities (the “what and why”)
Identify and pattern match high-value opportunities for AI across the product
Define what AI should do—and just as importantly, what it should not do, making hard or unpopular calls when needed
Set clear boundaries for autonomy vs human control
Design AI behavior, orchestration, and system logic
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
Develop and apply design principles and heuristics to shape how AI systems behave and make decisions
Ensure systems remain coherent and predictable, even as complexity scales
Shape human + AI workflows and end-to-end experience
Design experiences for users who are increasingly managing AI systems and agents
Design how AI integrates into real user workflows, not just isolated interactions
Define the role of the human in the loop: where users guide, review, or override
Ensure users can understand, trust, and recover from system failures
Partner with product designers to continuously shape and adapt the product experience as underlying systems evolve
Define quality, evaluation, and reliability
Define what “good” looks like (e.g. trust, accuracy, effort reduction, and whether outputs are structured and usable in context)
Design evaluation scenarios and feedback loops
Analyze outputs to identify failure modes and system weaknesses
Design for reliability at the system level, preventing agentic breakdowns
What We’re Looking For
Strong product judgment—you consistently make high-quality calls on what to build and why
Ability to influence without authority
Experience working on zero-to-one products and comfort operating through ambiguity and rapid change
Deep understanding of LLMs and their limitations, along with a grounding in traditional ML approaches and when to use them instead
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
We’re open to non-traditional backgrounds (e.g. product managers, engineers, or others) if you have strong product sense and a track record of representing user needs in technical systems
