About Popai
Popai is on a mission to transform the millions of conversations that happen between care teams and patients every day. We’re building the AI platform that turns every patient interaction into action - helping care teams understand what patients need, close gaps in care, and reach the people who need them most. Our goal is simple but ambitious: make healthcare more proactive, personal, and accessible for millions of patients.
This role spans our entire product stack. From React frontends to Node.js microservices, event-driven backends, and AI systems, you will build end-to-end features across Popai's product suite. You will collaborate closely with product, design, and AI teams to deliver high-impact solutions from concept to production.
