Software Engineering Cloud Engineering At Unity, we're building a world-class advertising platform that operates at a massive global scale. The Ads team powers the systems that connect advertisers with creators and players, driving performance, reliability, and growth across our ecosystem. As a Senior Full-Stack Engineer on the Unified Ads Platform team, you'll own the service layer where advertiser and publisher entities live. Campaigns and budget caps, applications and ad units, creative packs and the moderation pipeline behind them, offerwall currency, A/B tests, LevelPlay integration. These are the records the rest of the ads estate reads from, and our APIs are the source of truth for them across serving, billing, and reporting. This role goes beyond building an API and moving on. The data you model is consumed by systems you don't own, in paths where a wrong value costs money. You'll design contracts that stay secure as the product changes, keep state consistent across service boundaries, and own the correctness and availability of all of it in production. This role is ideal for someone strong on both sides of the stack who thinks in terms of data contracts and correctness, and who wants real ownership of systems other engineering teams depend on. As the team grows, this role has a path to evolve into a Tech Lead Manager position. What you'll be doingDesign, build, and operate services in our TypeScript platform (NestJS) across a large domain model, owning the APIs and data contracts that downstream ads systems depend onModel entity data for scale and change — relational schema design, migrations, and schema evolution against tables that serving, billing, and reporting all read fromDesign and build event-driven integrations with Kafka and Google Cloud Pub/Sub,



using patterns such as transactional outbox and idempotent consumers to maintain consistency across service boundaries.
Deliver the user-facing surfaces on top of the platform in React and TypeScript, turning dense entity and performance data into workflows publishers and advertisers can trustOperate what you build on Kubernetes, where the service declares its own cloud infrastructure alongside its code, and take real ownership of its SLOsDrive observability and quality across the platform — distributed tracing, metrics, and testing frameworksSet the standards for how the service is built and hold the line on them in design and code review, mentoring engineers as you go What we're looking for6+ years building and operating production software, with real depth on both backend services and modern frontendAdvanced TypeScript, and experience with an opinionated, modular Node backend framework — NestJS, or comparable dependency-injection and module architecturesStrong data modelling and SQL — schema design, migrations, and performance at scale, alongside the API versioning judgment that goes with it. You understand delivery semantics, ordering, and idempotency, and what happens when two systems disagreeAdvanced React, with strong judgment around component design, state management, and performance in data-intensive interfacesCloud-native operation — containerized services on Kubernetes, and comfort owning the system in production, including deployment, scaling, monitoring,
