* Built and led the Magnite Infrastructure Engineering team to own key production technologies including monitoring, alerting, metrics gathering, artifact repositories, code repositories, configuration management, provisioning, and application deployment, supporting tens of thousands of virtual and bare metal instances across 7 global data centers. * Owned and expanded the big data (Hadoop/Spark/HDFS/Kafka) infrastructure while continuing to meet ever more stringent data availability SLAs. * Guided the career growth for all levels of engineers, both onshore and offshore, helping to drive strong retention of talent while also providing the opportunity for some to become new leaders in our larger organization. * Created and led a new engineering team supporting on-premise and cloud based Kubernetes clusters.* Orchestrated the design and deployment of a multi-account AWS infrastructure in which resources were managed in an Infrastructure as Code (IaC) and infrastructure as a service (IaaS) model using a Terraform based CI/CD pipeline.* Managed infrastructure applications in a continuous integration/continuous deployment (CI/CD) environment leveraging GitHub and Jenkins pipelines in Groovy to improve stability. * Led the refactoring of a configuration management infrastructure ensuring consistent infrastructure across all environments and providing Magnite engineering resources the ability to safely manage global deployments. * Led the creation of an automated provisioning process for hardware and virtual machines reducing critical resource deployment times from days to minutes and allowing for a more rapid response to capacity needs for any application including Magnite core ad serving platforms. * Directed the creation of automation for hardware failure detection to ensure both high availability and efficient hardware maintenance cycles.* Made Infrastructure specific product decisions.
