Job description

We're Hiring: Backend Engineer (HMS) – MedOrbit, an AI-Native Hospital Platform

This isn't a "maintain a CRUD app" role. MedOrbit is already live with paying hospitals, runs the full clinical and operational spine of a hospital, and has 11 AI agents in production under clinician control. You'll build the backend that doctors, nurses, lab technicians, pharmacists and billing teams use every day.

Location: Nagarabhavi, Bangalore (On-site, 5 days a week)

Type: Full-time

Experience: 1–4 years

About MedOrbit

MedOrbit (by AI Nexus Innovations Hub) is a multi-tenant hospital management platform built for Indian healthcare. One codebase serves 24 facility types, from a solo doctor's clinic to a 500-bed super-specialty hospital, pathology labs, imaging centres, dialysis chains, blood banks and retail pharmacies.

What You'll Do

Core HMS Modules

Build and extend Java / Spring Boot microservices across patient registration, appointments, OPD/IPD workflows, bed management, lab orders, pharmacy inventory, billing and insurance claims

Design REST APIs and database schemas that work across 24 facility types without forking the codebase

mplement module licensing and multi-tenant data isolation so each hospital sees only what it has licensed

Healthcare Integrations

Work on ABDM flows: ABHA creation/linking, consent management, HIP/HIU data exchange

Build and maintain FHIR R4 resources, HL7 messages from lab analysers, and DICOM integration with PACS

Support NHCX claim submission and TPA workflows

AI Integration

Integrate Python-based AI services (ambient scribe, lab report intelligence, X-ray analysis, claim-denial guard) into the core platform

Build the APIs, queues and audit trails that let AI outputs appear inside doctor workflows, with clinician approval recorded every time

Reliability & Compliance

Write unit and integration tests, review code, and fix production issues quickly

Build audit logs, role-based access control, consent tracking and data-erasure features for DPDP and NABH compliance

Optimise queries and APIs for hospitals with high daily patient volumes

What You Bring

Must-Have:

B.Tech / B.E. / M.Tech / MCA in Computer Science or related field (2024–2026 batches welcome)

Hands-on experience building an HMS, EHR/EMR, LIS, RIS, pharmacy or clinic management system. Be ready to walk us through the modules you built, the database design, and the problems you solved

Strong fundamentals in Java and Spring Boot

Good understanding of REST APIs, SQL, joins, indexing and data modelling

Working knowledge of Git, Docker and Linux

Clear communication – you'll work with doctors and hospital staff, not just engineers

Nice-to-Have (Bonus Points!):

Exposure to FHIR, HL7, DICOM, ABDM, LOINC or ICD codes

Microservices architecture, Kafka / RabbitMQ, Redis caching

AWS (EC2, S3, RDS, Lambda) and CI/CD pipelines

Experience with insurance/TPA billing or GST-compliant invoicing

Basic Python or experience integrating ML/LLM services

Frontend exposure (React / Angular) for full-stack debugging
