At Magnite, we cultivate an environment of continuous growth and collaboration. Our work impacts what millions of people read, watch, and buy, and we’re looking for people to help us tackle that responsibility with creativity and focus. Magnite (NASDAQ : MGNI) is the world’s largest independent sell-side advertising platform. Publishers use our technology to monetize their content across all screens and formats including CTV / streaming, online video, display, and audio. Our tech fuels billions of transactions per day!

About this team : Magnite’s Reporting & Insights group powers our flagship analytics products — Performance Analytics (PA), Prebid Analytics (PBA), and the SpringServe platform's reporting — and is building the next‑generation Unified Reporting API. We’re adding a senior backend engineer to accelerate a high‑impact roadmap, elevate API developer experience, and partner closely with our UI and Data teams to ship features that our publishers and DSPs rely on to understand and optimize campaign performance.

Responsibilities

• Design, build, and evolve microservice‑based API products that power reporting and analytics applications.
• Collaborate daily with Product, UI, and Data engineers to take features end‑to‑end — from requirements and design to rollout, telemetry, and iteration.
• Design and build APIs that are intuitive and easy to consume : clear contracts (OpenAPI / gRPC), well‑documented, versioning strategies, pagination, filtering, batching, and strong SLAs / SLOs.
• Shape data access patterns : schemas, query plans, caching, and performance tuning in read / writes for big data.
• Champion code quality : well‑tested, observable, maintainable code; thoughtful reviews; design docs; and pragmatic documentation.
• Own services in production : dashboards, alerting, capacity and load testing, cost‑aware design, and reliability improvements.
• Mentor teammates, share knowledge, and help raise the technical bar across the organization.
