Company: Onicares AI Pvt Ltd (ONI) · Location: Remote (India) · Experience: 4+ years · Type: Full-time

About ONI

At ONI, we're building the technology infrastructure for the future of women's health. We started with prenatal care and have already built a clinical platform used by OB-GYNs, along with a connected care program for mothers. Our vision is a continuum care platform for women's reproductive health — from preconception and fertility through pregnancy, postpartum care, and beyond. We're an early-stage startup with real customers and real deployments.

About the Role

We are looking for a Senior Backend Engineer / Product Engineer who can take ownership of products end-to-end. This is not a role where you'll work on isolated tickets — you'll collaborate closely with founders, product, design, healthcare providers, and engineers to build, ship, and scale products used in real clinical environments. You'll wear multiple hats, make technical decisions, contribute to architecture, deploy services, work on integrations, and help shape our AI and data platform.

What You'll Do

• Build and maintain scalable backend services using Node.js and TypeScript
• Design APIs, databases, workflows, and system architecture for new products and features
• Build and deploy production-grade services on cloud infrastructure
• Design and optimize PostgreSQL databases and data pipelines
• Work on integrations with hospitals, clinics, laboratories, EMRs, and third-party healthcare systems
• Contribute to AI-powered workflows, LLM integrations, automation systems, and ML-driven product initiatives
• Lead projects from idea to production with minimal supervision; mentor junior engineers
• Work closely with customers and providers during onboarding, deployment, and troubleshooting

What We're Looking For

• 4+ years of experience building and shipping software products
• Strong experience with Node.js and TypeScript
• Strong understanding of backend architecture, APIs, databases, and distributed systems fundamentals
• Experience with PostgreSQL and database design; deploying and managing services in cloud environments
• Experience building products from scratch and owning them in production
• Comfortable in fast-moving startup environments with ambiguity; excellent communication and ownership mindset

Nice to Have: NestJS; React or React Native; Docker, Kubernetes, CI/CD; AI-powered products, LLM applications, RAG systems; healthcare, HIPAA, FHIR, EMR or hospital integrations; leading small teams.

Why Join ONI? Work directly with founders and influence product direction; build AI-first healthcare systems with real-world deployments; high ownership and autonomy from day one; help shape the engineering culture and technical roadmap.
