The opportunity Unity is building a robust, near real-time reporting platform that powers critical analytics and decision-making across our ecosystem. We are looking for a Senior Software Engineer to help architect and implement the distributed data systems that drive this platform at scale.

In this role, you’ll design and build high-throughput, low-latency data processing pipelines that power reporting used by internal teams and external customers. This is a high-impact role where engineering rigor, architectural clarity, and production ownership matter.

Own the end-to-end attribution pipeline. You will be a core engineer on the team responsible for getting attribution data right - from the moment a user interacts with an ad to the signal landing accurately in our data warehouse and in the hands of our ML and Reporting teams. This means owning a portfolio of high-throughput, latency-sensitive services and streaming pipelines that operate at the center of Unity’s mobile advertising infrastructure.

You will design, build, and operate the online services that receive ad interaction events from mobile SDKs and other partners, process terabytes of data at scale - including enrichments, transformations, and privacy operations - and deliver signals to external and internal partners in real time.

Lead our architectural modernization. This is greenfield development within a production system, requiring careful design with backfill and failover behavior while preserving data accuracy throughout the cutover.

Improve low-latency data services. You will improve the caching layer that serves data on every ad request within strict latency budgets, and own the persistence layer that links auction, fill, placement, and gamer identities together across the ad lifecycle.





Build and maintain critical ad serving infrastructure. You will build and own multiple services that support ad serving - including negative targeting and block listing - across the team’s service portfolio. Drive data health monitoring and quality. You will own real-time monitoring of data health, detecting anomalies, event delivery rates, and data quality signals as they happen. You will also build and maintain the batch data pipeline jobs that produce daily datasets in BigQuery.

Collaborate across ML, Reporting, and external partners. You will be the team that ML modeling, Reporting, and external partners rely on for timely and accurate signal reporting. Strong foundation in distributed systems and systems design
