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 stable 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 solid 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. Design, 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 on Model entity data for scale and change — relational schema design, migrations, and schema evolution against tables that serving, billing, and reporting all read from Deliver the user-facing surfaces on top of the platform in React and TypeScript,
