About The Position

Spring Health is a global mental health company working to eliminate barriers to mental health. Its AI-native platform provides personalized support through self-guided tools, coaching, therapy, medication management, and specialty care.

This work aims to reduce software delivery costs, improve system stability, and maintain consistent security across dependent teams. Reporting to the Senior Engineering Manager, Platform Core Services, the Software Engineer II will contribute to shared services, their underlying infrastructure and APIs, and systems that span team boundaries. The role includes delivering production-ready code, contributing to architectural discussions, collaborating with product, design, and engineering partners, and supporting system reliability through an on-call rotation. The engineer will use AI tools to assist development while applying human judgment and validating outputs before use. This is a hybrid role based in Seattle, with an expectation of working in the office 2–3 days per week at 255 S King St. Candidates must be based in the Seattle metro area or able to relocate independently within 90 days of their start date. Occasional travel for team on-sites is required.
