Lead the architecture and hands-on development of a greenfield multi-tenant HMIS platform with AI plug-ins, owning critical modules like multi-tenancy, billing engine, and offline sync.

About the Company

India Health Link Pvt. Ltd. is building a next-generation multi-tenant Hospital Management Information System (HMIS) — a single platform that serves many hospitals simultaneously. The platform is designed with optional AI plug-ins on top of a core that functions fully without them. This is a greenfield build, with the first pilot hospital going live in month 6. The company is headquartered in Chennai and is focused on transforming healthcare delivery in India through modern technology.

Role Overview

We are looking for a Tech Lead / Architect who will be the technical backbone of this product. This is a hands-on role where you will not only define the architecture but also write the hardest parts of the system yourself. The three most critical areas are multi-tenancy, the billing engine, and the offline synchronization layer — wrong early decisions here can cost six months of rework. You will own those decisions and ensure the platform is scalable, secure, and maintainable.

Key Responsibilities

• Own the architecture end to end, and record decisions as Architecture Decision Records (ADRs) that the team can still read a year later.
• Write code every week — at minimum the billing engine, the synchronization layer, and the tenancy core.
• Set and hold the review bar: schema design, migrations, API contracts, error handling, and tests.
• Break the roadmap into work that pods can run in parallel without blocking each other.
• Mentor two mid-level engineers actively, and make sure no module has a single point of failure after month 3 through pairing rotation.
• Work with the Business Analyst to turn hospital workflows into module specifications.
• Be accountable for the platform passing a third-party Vulnerability Assessment and Penetration Test (VAPT) in month 5.

Tech Stack

• Backend: TypeScript, NestJS (Node.js)
• Database: PostgreSQL 16, DynamoDB, Redis, OpenSearch
• Cloud & Infrastructure: AWS (ECS Fargate, RDS, S3, EventBridge, Amazon Bedrock)
• Frontend: React, React Native
• DevOps & CI/CD: Terraform, GitHub Actions, Playwright
• AI Services: Python, Amazon Bedrock (LLMs)

Your First 90 Days

• Month 1 — a walking skeleton in staging: log in, register a patient, book an appointment, bill a consultation. A thin slice through every layer, with CI/CD and environments live.
• Month 2 — orders hub, event outbox and audit spine in place; the OPD flow demoable.
• Month 3 — the demo build (OPD, laboratory, pharmacy and the Clinical Scribe AI plug-in) that the sales conversation runs on.

How We Work

Two-week sprints. Trunk-based development with short-lived branches. Code review on every pull request. Database changes only through migrations. Automated tests are mandatory around money, stock, and clinical-safety paths.

Requirements

• Shipped at least one multi-tenant SaaS product end to end and operated it in production — not only designed one.
• Deep PostgreSQL: indexing, query plans, transactions and isolation levels, partitioning, and migrations against live data with no downtime.
• Strong TypeScript and Node.js. NestJS specifically is a plus, not a requirement.
• Event-driven design in practice: the outbox pattern, idempotency, at-least-once delivery, replay.
• A managed-services mindset — you reach for RDS and Fargate before you reach for a Kubernetes cluster you have to run yourself.
• Has led a team of six or more engineers while still writing code.

Good to have:

• Healthcare systems experience: HL7, FHIR, DICOM, ABDM.
• Offline-first or synchronisation-heavy products.
• Ledger, payments or accounting domains.

Benefits

• Opportunity to own the architecture of a greenfield hospital management platform from day one.
• Work directly with the founder and head of product in a high-impact early-stage environment.
• Build and mentor a small team of mid-level engineers.
• Exposure to cutting-edge AI integration using Amazon Bedrock and event-driven design.
• Competitive compensation and equity potential for early employees.
• Flexible working arrangements with travel to pilot hospital in Chennai.
