Senior Full-Stack Developer for AI-Driven HealthTech Startup to $5000

About SageBridge

SageBridge is an early-stage, rapidly moving startup building an AI-powered digital assistant to help seniors stay organized and empower families caring for aging loved ones. We’re starting with core needs: tracking appointments, medications, symptoms, and essential information in one place.  We’re well into UX/UI design and are eager to find a Full-Stack Developer to join our team and help bring contemporary technology to the people who can most benefit from it — older adults and their families.
 

Founded by a former Salesforce exec and caregiver — with prior experience at HP and Nokia — we are moving fast toward a working MVP and already have a strong roadmap for post-MVP development.
