Job

Company

Role

Who you are

5+ years of software engineering experience, including 2+ years with Java
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)
Clear, empathetic communication and a collaborative mindset

Desirable

Exposure to cloud providers (AWS, GCP, or Azure) and container orchestration (Docker/Kubernetes)
Experience with event‑driven or streaming architectures
Experience with frameworks like Vert.x to build non-blocking, event-driven systems
Understanding of authN/Z patterns (OAuth2/JWT), rate limiting, and API security
Observability tools and practices (metrics, tracing, logs) and load/perf testing
Experience working with distributed/remote teams
Knowledge of Real-Time Bidding (RTB), SSPs, DSPs, and ad delivery systems is a strong plus
Experience with Terraform

What the job involves

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
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

Our take

Due to the rise in mobile and smart devices in recent years, the way in which advertisement publishers must format their ads is changing. A key example of this is TV, advertisements that present immediate calls to action within a Connected TV user interface, but publishing ads in such a format is currently inaccessible to most publishers.

Magnite provides a sell-side omnichannel advertisement platform for publishers, focused on facilitating the selling of advertising on all formats including CTV, mobile, desktop, and audio. In addition to facilitating the buying and selling of omnichannel ads, the company also provides a real-time ad performance dashboard, data protection and compliance tools, and insights into buying and selling patterns.

Whilst other omnichannel advertisement platforms present significant competition to the company, Magnite stands out by providing an end-to-end marketplace for the buying, selling, management, and analysis of ads. Furthermore, by focussing its efforts on cutting-edge formats such as CTV, the company shows great potential to futureproof itself within the advertisement industry.
