Hybrid Schedule (M/F remote, T/W/TH in-office)

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

We’re the Ad Server Engineering team at Magnite, responsible for building and maintaining the core systems that power real-time ad delivery across display and CTV platforms. Our team owns high-throughput services involved in auction handling, bid evaluation, and creative rendering—ensuring performance, reliability, and compliance at scale.

We are seeking a Staff Engineer to join our team, focusing on building, scaling, and modernizing our high-performance ad server. This role involves designing and implementing scalable, low-latency solutions to handle millions of queries per second (QPS), modernizing legacy systems, and building new features to support our product roadmap and quarterly commitments.

You will work on various aspects of ad serving, leveraging cutting-edge AWS infrastructure and frameworks such as Vert.x and Spring Boot. You will also utilize relational databases like MySQL and PostgreSQL alongside Aerospike, a highly scalable and reliable NoSQL solution. By integrating tools like Datadog and Grafana, you'll develop robust, scalable, and observable solutions to meet the evolving demands of ad tech.

Key Responsibilities

System Design & Development

• Develop scalable, low-latency solutions to support ad-serving operations, ensuring response times in milliseconds.

• Architect and optimize multithreaded, non-blocking systems using frameworks such as Vert.x.

Feature Development

• Collaborate with product teams to understand requirements, design technical solutions, and deliver high-quality features to support business goals.

• Ensure that new features are robust, scalable, and aligned with system architecture principles.

Modernization and Developer Experience

• Lead the modernization of legacy Java/Tomcat systems, implementing best practices, upgrading frameworks, and adopting modern technologies.

• Improve developer experience by integrating tools such as SonarQube, CI/CD pipelines, and testing frameworks.

• Drive the adoption of containerized and orchestrated deployments using Docker, ECS and Kubernetes (EKS).

Monitoring and Observability

• Design and implement robust monitoring and observability systems using AWS-native tools (CloudWatch, etc) and third-party tools (Datadog, Grafana).

• Establish real-time alerting, logging, and distributed tracing systems to ensure platform health and reliability.

Cloud Infrastructure and Data Management

• Leverage AWS infrastructure (ECS, EKS, S3, RDS) to build and optimize services.

• Architect and implement scalable storage and caching solutions using Aerospike, Memcached, Redis, etc.

Technical Leadership

• Mentor and guide engineers, providing technical leadership and fostering a culture of engineering excellence.

• Collaborate with cross-functional teams to prioritize features, address technical debt, and improve system reliability.

Ad Tech Expertise

• Address domain-specific challenges such as Real-Time Bidding (RTB), ad delivery, reporting, and data pipeline optimization.

Skills and Experience

Technical Expertise

• Strong expertise in multithreaded programming and non-blocking frameworks like Vert.x.

• Proficiency in Java (modern frameworks such as Spring Boot are a plus).

• Experienced in designing and optimizing distributed systems for high throughput, low latency, and high availability and reliability.
