Staff AI Interaction Designer

Spring Health is a global mental health company on a mission to eliminate every barrier to mental health. We're building a world where getting support is simple, personal, and built around the person, so care can continue through every job, move, health plan, and life stage.

Our AI-native platform helps us deliver personalized support across self-guided tools, coaching, therapy, medication management, and specialty care. With outcomes independently validated by JAMA Network Open and the Validation Institute, Spring Health reaches more than 170 million people worldwide through leading employers, health plans, and partners.

As an AI-native company, we believe technology should expand the reach, quality, and humanity of care. Every Spring Health team member is expected to use AI tools thoughtfully, apply human judgment to AI outputs, and keep building AI fluency in ways that support their role and our mission.

The mission of the AI Interaction Designer is to create an empathetic, clinically valid, and effortless AI experience for our end-users. This includes shaping the language, tone, behavior, 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 exceptional writing, best-in-class conversation design, thoughtful AI interaction patterns, rigorous evaluation, and continuous iteration.

This is a highly writing-focused design role. You should be as passionate about finding the right words for an AI response as you are about designing the experience around it.

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.
