From brilliant creatives, to technology trailblazers, across the globe, WBD offers career defining opportunities, thoughtfully curated benefits, and the tools to explore and grow into your best selves. Here you are supported, here you are celebrated, here you can thrive.

The Direct to Consumer (DTC) Group is a technology company within Warner Bros Discovery. We are building a global streaming video platform (OTT), and a suite of applications to support all of our network’s brands globally. We are building modern container-based micro-services operated on AWS. Our platform covers everything from search, catalogue, video transcoding, personalization, to global subscriptions, and really much more. We build user experiences ranging from classic lean-back viewing to interactive learning applications.  We build for connected TVs, web, mobile phones, tablets, and consoles for a large footprint of WBD owned networks (Max, Discovery, Food Network, Golf TV, MotorTrend, Eurosport, Discovery Play, and many more).  This is a growing, global engineering group crucial to WBD’s future. 

We are hiring a Senior Software Engineer within the DTC Operational Engineering group with focus on Cluster Engineering. The team is dedicated to provide a secure, efficient and easy-to-use container runtime platform. We build automation for expanding it to new markets, tenants and geographical regions, bootstrapping a fully featured container runtime ready for back-end development teams to use.

We team up with other platform teams, manage the lifecycle of critical platform components and work closely with SRE to improve reliability and efficiency of the platform.

We provide strategies and processes for lifecycle management of the container runtime environment. We own critical components, assess when we should introduce new ones, and set the bar for quality. We focus on reducing security incidents while ensuring cost-effectiveness and supporting business needs.

Responsibilities include, but are not limited to, operating Kubernetes clusters (version upgrades and managing critical Kubernetes components like Karpenter), security vulnerability mitigations (rolling out security patches to Kubernetes nodes) and cost optimizations (scaling of our thousands of servers running hundreds of in-house built services, supporting millions of customers across the globe).

As a Senior Software Engineer on the team, you will work with Kubernetes cluster operational tasks like upgrading the Kubernetes version. This includes performing an analysis of what is changing in the new version and how it affects the workload running on each cluster, e.g. deprecated k8s APIs and controller compatibility. You’ll use tools to scan clusters for finding things that need remediation, define actions for it, as well as executing them. As part of rolling out upgrades to hundreds of clusters, some ranging up to a thousand nodes, you will identify automation opportunities to reduce the amount of toil needed.

To achieve your goals, you’ll innovate using AI and improve existing processes and operations using agentic workflows. You’ll also contribute to the organization’s AI skills and plugins and advocate AI best practices across the wider organization.

In order to keep our runtime cost low, you will take part in cost optimization efforts, like tweaking the Karpenter node scaling strategies, increasing the bin-packing efficiency of pods on nodes, ensuring the right node family type is used (m, c, r, spot and Graviton/ARM) and identifying over scaled infrastructure.

To enable faster time to new markets and onboarding of new tenants to our streaming platform, you’ll work on automating the creation of new Kubernetes clusters together with bootstrapping of critical platform capabilities like service mesh, deployment systems and the observability stack.
