The Trade Desk is a global technology company and the world's leading independent platform for digital advertising, with nearly 4,000 employees across more than 30 offices. Our technology helps advertisers reach the right audiences across the open internet - from streaming TV and podcasts to mobile apps, news, and more. Advertising powers the content people love. By making it more transparent, effective, and responsible, we help support trusted journalism, quality entertainment, and creators worldwide. The world's brands and agencies rely on us to reach their customers and grow their businesses responsibly. The scale of our platform brings unique technical challenges - from processing massive datasets in real time to building systems that operate reliably on a global scale. When you work here, your impact is worldwide. We welcome diverse perspectives, encourage curiosity, and build teams that learn from one another. If you're driven to solve meaningful challenges, we'd love to meet you.Who we are:Ventura OS is a new Smart TV operating system being built inside The Trade Desk, the world's leading independent platform for digital advertising. Where the wider company runs a global-scale DSP, Ventura is closer to a startup inside it: a small team, direct influence over product direction, and a real OS shipping to real devices in real living rooms.We're deliberately building the CTV supply chain differently: more efficient for advertisers and publishers, more relevant for viewers, and more transparent end-to-end. The backend that powers all of it is being built now, and the Infra team is the critical foundation for it.About the Team:Infra is the foundation Ventura OS is built on. We own the compute, storage, and networking, including our Kubernetes platform, that every Ventura runs on, plus the source control and CI/CD pipelines that turn code into shipped products. We power the GPU and ML-serving infrastructure behind applied science and AI-assisted tools. We own every build system across AOSP platform, client experience and mobile, along with the lab infrastructure and release pipelines that keep platform engineering moving. We run build-test-deploy infrastructure for every app in the Ventura ecosystem, first-party and third. And we deliver telemetry end to end - from client ingestion to the dashboards leadership reads.If it runs, ships, trains, or gets measured on Ventura OS, it runs on infrastructure we built.What You'll Do:You'll be an end-to-end owner of the systems this team runs - designing, building, operating, monitoring, and setting the standards other inherit. As a member of the Infrastructure team, you'll be responsible for the scalability, performance, reliability, and visibility of every cloud service powering Ventura TV OS.In addition to the core responsibilities of a backend engineer, you will: * Build, automate, and operate the compute (VMs, Kubernetes), networking (VPN, edge services), database (SQL/NoSQL), storage, and identity services every Ventura partner team depends on - using infrastructure-as-code and automation-first practices, and forecasting capacity needs ahead of demand for compute, storage, and GPU resources. * Partner with application teams to design, implement, and scale the services and infrastructure behind their products. * Own the identity, security, and compliance model for Ventura OS cloud services - authentication, authorization, audit, and adherence to security and compliance standards for every request, from internal employees to external partners. * Monitor, troubleshoot, and optimize system performance and cost while balancing availability, efficiency, and cloud spend across the infrastructure we run. * Deliver highly available build infrastructure (GitLab, Jenkins, Gerrit) and developer tooling relied on by internal engineers and external partner vendors alike. * Own AOSP platform, client experience and mobile build systems, lab infrastructure, release pi
