# Senior Software Engineer, Backend Infrastructure

The opportunity Unity Spark is our browser-based game editor, with an ambitious vision for how real-time 3D games are created, shared, and played on the web. As a Senior Backend Infrastructure Engineer on the Spark team, you will be the engineer who makes our services build, ship, and scale. You will write backend code, and you will own how it reaches production on Google Cloud: the CI/CD pipelines, the infrastructure as code, the Kubernetes workloads, and the fleets of stateful real-time servers behind multi-user editing. Our team moves fast and uses AI coding tools every day. That shifts the work from typing code to deciding what to build, checking it is right, and owning it once it is live. We value generalists who pick up whatever the product needs next, whether that is a new service, a scaling problem, or a failed deployment. You will work closely with backend engineers, product, and partner infrastructure teams, and be the go-to person when production needs to scale or is not behaving. What you'll be doing Design, build, and maintain the CI/CD pipelines that take our services from pull request to production, with GitOps-style deployment Own infrastructure as code for our Goog
