At Index Exchange, we’re reinventing how digital advertising works—at scale. As a global advertising supply-side platform, we empower the world’s leading media owners and marketers to thrive in a programmatic, privacy-first ecosystem. Our platform is vertically integrated from servers to networks and runs primarily on our own metal and cloud infrastructure.

At the core of it all is our engineering-first culture. From moving petabytes of data and optimizing with AI to making real-time infrastructure decisions, Indexers have the agency and influence to shape the future of advertising.

Cloud Platform

Engineering builds the platform that makes all of this possible. We architect and deliver the foundational infrastructure—Kubernetes clusters, deployment pipelines, infrastructure-as-code frameworks, container platforms, storage systems—and the software layer on top of it: standard libraries, internal SDKs, platform APIs, and the interfaces that every engineering team at Index Exchange builds on top of. Platform engineering here is software engineering. our operational counterpart, Systems Engineering, carries that load.

We stay focused on what moves the needle: designing and building systems at scale. As a Staff Platform Engineer, you will own architectural decisions, deliver large-scale infrastructure projects, and shape the technical direction of a platform that processes more real-time transactions than almost any system on earth. We build, scale, and maintain Index Cloud —a multi-tenant, globally distributed compute platform that serves both our exchange workloads and the workloads of every partner in our ecosystem.

It’s building a platform-as-a-product at internet scale. You’ll design and deliver multi-tenant Kubernetes infrastructure across bare-metal and public cloud, build infrastructure-as-code frameworks that push changes across thousands of servers, and write the standard libraries, SDKs,



and platform APIs that every engineering team at Index Exchange depends on. Multi-datacenter consistency.

Deploying safely to a fleet of thousands. You’ll drive technical direction through RFCs and design reviews, set standards for shared platform domains, and make the calls on tooling, security posture, and system design. This is a Staff-level role—you’ll influence engineering direction across multiple divisions. # Build golden paths, self-service tooling, and platform APIs that let engineering teams ship without friction.

Coach engineers, foster a culture of engineering excellence, and collaborate across Cloud Platform Operations, SRE, Network, Security, and Software Engineering teams. You’ve built and shipped platform infrastructure at scale—not just operated someone else’s. You think in systems, you’re comfortable with ambiguity, and you care as much about the developer experience of your platform as you do about its architecture. 8+ years in platform engineering, SRE, infrastructure engineering, or DevOps. ~ Deep experience with Linux internals: kernel tuning, network stack, system observability, security. ~ Strong Kubernetes expertise: cluster lifecycle, networking, storage, RBAC, multi-cluster—across bare-metal and cloud (EKS, GKE). ~ Proficiency in Go, Python, or both—for building libraries, SDKs, and platform APIs, not just scripts. ~ Solid networking fundamentals (L2-L7), load balancing, DNS, service discovery.



~ A track record of driving technical strategy across teams—not just executing within one.

Big data infrastructure: Secrets management (Vault), certificate management, access control at scale.

Hybrid cloud architectures: federating public cloud (AWS, GCP) with on-premises environments.

Experience with bare-metal infrastructure in globally distributed data centers We don’t care whether you call yourself a platform engineer, an SRE, a DevOps engineer, or a systems engineer. Treats operational readiness as a first-class engineering concern, not an afterthought. Prefers building the right abstraction over fighting the same fire twice.
