About the RoleWe’re looking for a Head of Engineering to help build the technical foundation for the future of women’s healthcare. At Evvy, engineering sits at the center of everything we do — from diagnostics and patient experiences to AI-powered personalization, clinical operations, and data infrastructure. This role is about using modern engineering and AI-native development to dramatically increase the speed, leverage, and ambition of what a small team can accomplish. As Head of Engineering, you’ll report directly to the CEO and lead Evvy’s technical vision, architecture, and execution as we scale.
