Spring Health•San Francisco, CA

3d•$182,000 - $242,000•Hybrid

About The Position

The mission of the AI Interaction Designer is to create an empathetic, clinically valid, and effortless AI experience for our end-users. This includes designing the parameters, tone, and interaction flows for our user-facing AI agents to drive meaningful behavior change and internal motivation. Reporting to our Senior Manager, Product Design, you will be part of the Design Systems team, and partner closely with clinical and engineering teams to execute our AI product roadmap through best-in-class conversation design, rigorous evaluation, and continuous iteration. This is a hybrid role based in New York City, with an expectation to be in the office 2–3 days per week at our 60 Madison Avenue location. Candidates must be based in the NYC metro area or able to relocate independently within 90 days of their start date. Occasional travel will be required for team on-sites.

Requirements

5+ years of experience in UX/Product Design, with at least 1-2 years focused on AI-driven products, LLMs, or conversational agents.
Deep intellectual curiosity and a drive to tinker. You don't treat AI as a novelty—you actively use it as a collaborator to think better and accelerate your own workflows.
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.

Nice To Haves

Experience integrating AI patterns into existing design systems (e.g., Figma).
Experience integrating AI UX eval methods into spec-driven agentic workflows
Experience in the benefits or mental health space.

Responsibilities

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.
