DevOps / Site Reliability Engineer – Engineering

DevOps / Site Reliability Engineer – Engineering Experience: 6+ Years Location: Kolkata, India / Gurgaon, India (On-site) Shift: Normal or Night — depending on candidate preference and business need Reports to: Lead DevOps / SRE Employment Type: Full-time About Practice by Numbers Practice by Numbers (PbN) is a fast-growing SaaS platform helping healthcare organizations leverage data, automation, patient engagement, and operational intelligence to improve business performance and patient outcomes. We build highly scalable cloud-native products serving thousands of customers across North America. We are looking for a DevOps/SRE Engineer who writes Terraform and CI/CD pipelines. This is a builder’s role, not a monitoring seat. Role Overview You will own Terraform modules across our AWS infrastructure — compute, networking, databases, IAM, DNS — and build the GitHub Actions pipelines that ship our Django, Python, Node.js, and React services. This role can be staffed on a normal shift or a night shift, depending on your preference and our coverage needs. On a night shift you get an uninterrupted window for the changes that are hardest to make in daylight — database migrations, pipeline rewrites, provider upgrades, and staged cutovers — and you will often be the only engineer on shift. That means real autonomy, real ownership, and the expectation that you can reason through an unfamiliar system on your own and write up clearly what you did. This role suits someone who wants deep infrastructure work with production ownership and prefers building over ticket-shuffling. Key Responsibilities Infrastructure as Code Own and extend Terraform modules across AWS — ECS/Fargate or EKS, RDS, VPC networking, IAM, ALB/NLB, S3, Route 53, CloudWatch. Manage Terraform state safely; write and review plans that reviewers can trust. Eliminate manually created resources by bringing them under code (via terraform import, refactors, and module extraction). Keep environments (dev, QA, production) consistent and reproducible. CI/CD Engineering Build and maintain GitHub Actions pipelines for build, test, containerization, and deployment. Migrate legacy pipelines (Jenkins, CircleCI, GitLab CI) onto a single, maintainable platform. Design safe deployment paths — staged rollouts, health-gated releases, fast and reliable rollback. Keep pipelines fast: caching, parallelism, test splitting, and honest gating. Reliability & Operations Own the production change window on your shift: deploys, migrations, cutovers, and maintenance. Run and improve observability — dashboards, SLOs, alerting that fires on real user impact rather than noise. Debug containerized applications in production: logs, metrics, traces, resource limits, networking. Participate in on-call rotation and incident response; drive blameless post-incident reviews. Improve cost efficiency and resource utilization across the AWS footprint. Databases…
