About the role

Key responsibilities & impact

Design the human-AI interaction experience for Spring Health's user-facing AI agents across web and mobile platforms.
Own the intent architecture end-to-end (taxonomy, routing, and gap analysis) and drive release rigor for AI experiences, including versioning, staged rollouts, and regression testing.
Write, test, and optimize system prompts and exceptional UX copy. You will craft language that makes users in moments of distress feel seen, heard, and important—motivating and uplifting them without ever being dismissive of their challenges.
Partner deeply with Clinical and Product teams to ensure AI interactions drive clinically valid behavior change, focusing on internal motivation.
Define conversational parameters and graceful error handling for edge cases, hallucinations, or ambiguous user intent.
Collaborate with engineers to implement prompt versioning and evaluate conversational quality using testing frameworks.
Design and prototype chat interfaces, considering latency, tool-calling UI, and user onboarding within our core design system.
Act as a strategic design leader, regularly presenting conversational architecture, AI performance insights, and product vision to executives and extended leadership teams.

Requirements

What you’ll need

5+ years of experience in UX/Product Design, with at least 1-2 years focused on AI-driven products, LLMs, or conversational agents.

Strong portfolio demonstrating complex human-AI interaction design, underlying logic, and user flows.
Deep understanding of LLM capabilities and constraints (e.g., context windows, streaming).
Familiarity with prompt engineering and testing methodologies.
A passion for incorporating user insights into evals and other metrics to improve conversational quality.
Strong cross-functional collaboration skills, particularly with engineering and clinical experts.
Top-notch communication and executive presence. You excel at cross-functional collaboration and can articulate complex AI and design concepts clearly to organizational leadership.
