Magnite's Reporting & Insights group is building the next-generation Unified Reporting API and needs a senior backend engineer to accelerate its roadmap, improve API developer experience, and deliver features that publishers and DSPs rely on for campaign performance optimization.

Requirements

  • 5+ years of software engineering experience, including 2+ years with Scala (or equivalent JVM experience with a strong desire to specialize in Scala).
  • Deep understanding of microservice fundamentals (service boundaries, resiliency, observability, CI/CD) and API design at scale.
  • Hands‑on experience with MySQL (or other RDBMS): modeling, migrations, indexing, and query optimization.
  • A track record of shipping well‑tested, production‑grade APIs used by UI applications and direct API consumers.
  • Proficiency with Git/GitHub and modern team practices (reviews, trunk/branch strategies, code ownership).
  • Exposure to cloud providers (AWS, GCP, or Azure) and container orchestration (Docker/Kubernetes).
  • Familiarity with functional programming concepts and Scala FP libraries.

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.
  • Craft APIs that are a joy to use: clear contracts (OpenAPI/gRPC), 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.

Other

  • Hybrid Schedule (M/F remote, T/W/TH in-office)
  • Clear, empathetic communication and a collaborative mindset.
  • Experience with distributed/remote teams.
  • Knowledge of Real-Time Bidding (RTB), SSPs, DSPs, and ad delivery systems is a strong plus.
  • The base salary range for this position is: $145,000 - $155,000 in addition to an annual variable bonus based on performance and company equity
