Senior Software Engineer, Attribution

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 Staff 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. You’ll operate at the intersection of distributed systems, stream processing, and cloud-native infrastructure — ensuring correctness, reliability, and scalability in a high-volume production environment.

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 responsible for delivering accurate attribution data — 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 includes ownership of high-throughput, latency‑sensitive services and streaming pipelines at the center of Unity’s mobile advertising infrastructure.
• Build and operate real‑time ad event processing: design, build, and operate online services that receive ad interaction events from mobile SDKs and partners, process terabytes of data at scale (enrichments, transformations, privacy) and deliver signals to external and internal partners in real time.
• Lead architectural modernization: lead an active migration, replacing a legacy event‑handling layer with a modern gRPC‑based service. This is greenfield development within a production system, requiring careful design with backfill, fail­over behavior, and data accuracy preservation throughout the cutover.
• Develop low‑latency data services using caches: improve the caching layer that serves ad request data within strict latency budgets and own the persistence layer linking auction, fill, placement, and gamer identities across the ad lifecycle.
• Build and maintain critical ad‑serving infrastructure: build and own multiple services that support ad serving (negative targeting, block listing, etc.), and produce logging, tracing, authentication, Kafka‑backed caching, health‑check, readiness probe infrastructure, and Docker‑based integrations.
• Drive data health monitoring and quality: own real‑time monitoring of data health, detect anomalies, event delivery rates, and data quality signals as they happen. Build and maintain batch data pipeline jobs that produce daily datasets in Big Query.
• Collaborate across ML, Reporting, and external partners: be the team that ML modeling, Reporting, and external partners rely on for timely and accurate signal reporting. When issues arise, lead the investigation and recovery.

• Strong foundation in distributed systems and systems design.
• Hands‑on experience building and operating large‑scale data processing systems.
• Deep understanding of streaming concepts: exactly‑once semantics, watermarking and event‑time processing, stateful stream processing, checkpointing and recovery, back pressure handling.
• Production experience with frameworks such as Apache Flink, Spark, Kafka, or similar technologies.
• Proficiency in Python, Java, or Scala.
• Experience with workflow orchestration tools (e.g., Airflow) for stream and batch coordination.
• Strong understanding of cloud‑native architectures and distributed infrastructure (Kubernetes, containerization, cloud platforms).

• Relocation support is not available for this position.
• Work visa/immigration sponsorship is not available for this position.
