DevOps / Cloud Engineer

Positions - 1 Experience - 4–6 years Reports to- Tech Lead / Architect Location - Chennai with occasional travel to the pilot hospital Type- Full-time About the company and the product India Health Link is building a new multi-tenant Hospital Management Information System (HMIS) — one platform serving many hospitals — with Artificial Intelligence (AI) features delivered as optional plug-ins on top of a core that works fully without them. It is a greenfield build, and the first pilot hospital goes live in month 6. Our stack : Amazon Web Services (AWS), Terraform, GitHub Actions, Docker, TypeScript and NestJS services, PostgreSQL 16, Python for the AI services. What you will build          •        The whole AWS footprint as Terraform code : Virtual Private Cloud (VPC), Elastic Container Service (ECS) Fargate, Relational Database Service (RDS) PostgreSQL, DynamoDB, Simple Storage Service (S3), OpenSearch, Redis, EventBridge and CloudFront.          •        Continuous integration and deployment (CI/CD) on GitHub Actions: build, test, migrate, deploy, roll back. Deployment must be boring.          •        Environments : development, staging, pre-production with anonymised data, and production.          •        Monitoring and alerting that a twelve-person team can actually respond to, with centralised logs and traces.          •        Backup and disaster recovery with a tested restore, not a documented one.          •        The on-premise edge gateway image that runs inside a hospital's local network for analyser connectivity and Local Area Network mode when the internet is down. Responsibilities          •        Own infrastructure cost, keep it inside the agreed monthly budget, and report it monthly.          •        Own security hygiene: least-privilege identity and access management (IAM), secrets management, encryption at rest and in transit, patching, and network boundaries.          •        Own remediation for the Vulnerability Assessment and Penetration Test (VAPT) in month 5 — coordinate the external firm and drive every finding to closure.          •        Make the developer experience good. A new engineer should be productive on day two.          •        Set up data-residency arrangements appropriate to Indian health data.          •        Be the person who can tell, at 2 am, whether the problem is our service, the database, or the hospital's internet connection. Requirements          •        Four or more years on AWS in production, including ECS or equivalent container orchestration, RDS, IAM and VPC networking.          •        Terraform written and maintained by you, with proper modules and state management.          •        Ownership of a CI/CD pipeline, including the database migration step.          •        Observability in practice: you have been on call, and you have tuned alerts that were too noisy.          •        Linux and networking fundamentals —…
