Staff Software Development Engineerin in Test

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.

We’re a proud industry pioneer with over 20 years of experience accelerating the ad technology evolution. Our proprietary tech is trusted by some of the world’s largest brands and media owners and plays a crucial role in keeping the internet open, accessible, and largely free.

We process more than 550 billion real-time auctions every day (in comparison, Google processes 8.5 billion searches per day) with ultra-low latency. Our platform is vertically integrated from servers to networks and runs primarily on our own metal and cloud infrastructure. This end-to-end infrastructure is designed to provide both stability and agility, enabling us to adapt quickly as the market evolves.

At the core of it all is our engineering-first culture. Our engineers tackle internet-scale problems across tight-knit, global teams. 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. We move fast, build thoughtfully, and stay grounded in our core values.

We are looking for a Staff Software Development Engineer in Test (SDET) to serve as a technical leader and quality champion across Index. This is a hands-on individual contributor role with broad cross-team and cross-divisional influence where you will define and drive modern quality engineering practices, build scalable automation, tools, test infrastructure, and enable teams to deliver high-quality, high-performance software with confidence.

You will operate at the intersection of architecture, quality, developer experience, and operations, ensuring quality is built into every stage of the software lifecycle. You will also leverage AI to improve testing efficiency and insights.

As a SDET champion on the engineering team, you will own the vision for test infrastructures, build frameworks that allow developers to easily write reliable tests, and invent new mechanisms for ensuring that every change we make can be deployed safely and quickly. You will help solve our most difficult challenges and will coach other engineers to foster a culture of relentless high standards.

This position reports directly to Senior Engineering Manager based in Bangalore and will work closely with members of the Quality and Delivery teams.

Additionally, we realize that diversity is deeper than any status or classification—diversity is the human experience. For those who show grit, passion, and humility—Index will welcome you.
