Nice To Haves * Experience working in the CTV space and familiarity with its unique delivery constraints. * Expertise in high-throughput data processing systems and telemetry frameworks for large-scale production environments. * Familiarity with cloud-native infrastructure, deployment automation, and SLO-driven development. ## Description The Core Ad Serving Platform team designs and builds scalable, modular backend frameworks and libraries that serve as the foundation of ads platform. You will focus on creating resilient systems that power a wide range of ad products and features while ensuring high availability, low latency, and maintainability as the platform evolves. What Success Looks Like * Dynamic: You thrive in critically impactful environments where you maintain platform stability under high throughput. * Hands-on Ownership: You are a builder. You're comfortable navigating complex distributed systems, identifying bottlenecks, and writing code to solve them-not just whiteboarding solutions. You own the full lifecycle of your services-from design and deployment to capacity modeling and incident response. * Contextual Decision Making: You possess the judgment to align technical tradeoffs with business goals, ensuring our ad serving infrastructure scales gracefully as we continue to grow. What You'll Do * Architect and operate backend services for core ad decisioning: Design and build scalable, modular backend frameworks for targeting, frequency management, pacing, and policy enforcement. * Design APIs and data models: Create clean, scalable interfaces and data schemas that enable seamless interoperability across the Ad Platform ecosystem. * Optimize high-throughput serving: Build services that manage ad selection and delivery consistency, ensuring low-latency performance in high-traffic, distributed environments. * Drive operational excellence: Implement SLO-driven development and proactive capacity planning, and own the incident response lifecycle for the core serving stack. * Instrument platform reliability: Develop comprehensive diagnostics, logging, and telemetry frameworks to ensure deep observability into system health and reliability. * Maintain ad-tech domain expertise: Utilize deep knowledge of advertising concepts (publisher policies, frequency caps, targeting) to ensure the platform meets industry standards and business requirements. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Swapping Low Latency Data Storage Under High Load](https://www.wearedevelopers.com/videos/746-swapping-low-latency-data-storage-under-high-load) - [Crypto-secure Data Management with In-Database Blockchain](https://www.wearedevelopers.com/videos/632-crypto-secure-data-management-with-in-database-blockchain) - [DevOps at Netflix](https://www.wearedevelopers.com/videos/270-devops-at-netflix) - [Super scaling for the Super Bowl: How to survive 30 million users hitting your backend in 30 minutes](https://www.wearedevelopers.com/videos/100356-super-scaling-for-the-super-bowl-how-to-survive-30-million-users-hitting-your-backend-in-30-minutes) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story)
