Platform Engineer

Platform Engineer

Are you the kind of engineer who sees a cluster not as plumbing but as the foundation on which real lives depend? At Sand, you'll own the Kubernetes platform that ministries of health use to make decisions for millions of people. It's expanding country by country: a growing fleet that spans managed cloud and self-managed, sovereign on-premises clusters, because where health data must live is the law, not a preference. Every new deployment is a fresh reliability problem, not a copy-paste when a cluster wobbles, a health worker loses the data they need. You'll automate relentlessly, codify everything with GitOps, and maintain a single operating standard across the whole estate. If you're as curious about the lives behind the systems as you are about the systems themselves, this is your foundation to build on.

From intelligent command centers to AI-powered infrastructure platforms, we help organizations sense, analyze, and act in complex environments.

About the role

As our platforms scale across industries and deployment environments, we’re looking for a Platform Engineer who lives and breathes Kubernetes. You’ll own the foundations that everything else at Sand runs on — designing, operating, and hardening the clusters, pipelines, and reliability practices that let our product and delivery teams ship critical systems with confidence.

This is a deeply hands-on site reliability role. You’ll work across managed cloud Kubernetes and self-managed on-premises clusters, treat infrastructure as code, automate relentlessly through GitOps, and build the observability and operational discipline that keeps mission-critical workloads healthy.
