The role focuses on developing high-throughput, low-latency distributed systems capable of processing billions of bid requests per day while delivering optimized bidding decisions within strict latency constraints. You will experiment with new and innovative technologies designed for Programmatic Ad serving and Ad Tech solutions. You will work on the core bidding infrastructure, targeting systems, and integrations with supply partners to drive efficient ad delivery and maximize campaign performance. This role will be based in our NYC local office. Our team follows a hybrid schedule, working in the office three days a week and remotely for the rest. Each day can be different here at Nexxen, but some of the things you can expect to be doing daily are: What You'll Do: * Design and develop high-performance distributed systems handling large-scale bid request traffic with sub-100ms latency requirements. * Build and optimize real-time bidding (RTB) services that evaluate targeting rules, campaign budgets, and bidding strategies in real time. * Implement efficient caching layers and in-memory data stores using technologies such as Redis, MongoDB, etc. * Monitor and improve system performance through observability, load testing, and capacity planning. * Develop and maintain reliable, scalable, and efficient backend services using modern technologies and frameworks * Write high-quality, well-tested code that is maintainable and adheres to best practices in software engineering * Analyze data to drive decision making and assess the impact of system changes. * Follow agile methodologies and work in a fast-paced environment where results are quickly visible ## Related Videos - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [Branch your database like your code: How schema changes and pull requests go hand in hand](https://www.wearedevelopers.com/videos/350-branch-your-database-like-your-code-how-schema-changes-and-pull-requests-go-hand-in-hand) - [Coding for Good: Achieving social change with an app](https://www.wearedevelopers.com/videos/1645-coding-for-good-achieving-social-change-with-an-app) ## Related Articles - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [7 Important Tips That Every Software Developer Should Know](https://www.wearedevelopers.com/magazine/101-7-important-tips-that-every-software-developer-should-know)
