At Quantcast, we use technology to help brands and publishers understand, reach and influence the constantly-changing behaviors of consumers. The Real-time Bidding Platform owns and operates the large scale distributed stack which allocates millions of dollars of advertising budget to billions of bid opportunities streaming into the system. If you’re interested in working on these critical, fast, large scale distributed systems then we’d like to meet you.

Working side-by-side with engineers and modeling scientists you will build and operate intelligent bidding, optimization, prediction and control systems that power different parts of this stack. You’ll lead cross team projects to optimize the throughput of the stack while reducing costs and increasing advertising performance. You’ll drive design and implementation of new products for clients that’ll involve multiple teams and services.

• Scaling our bidding systems to process millions of requests per second
• Optimize control systems listening to and controlling thousands of bidding machines in AWS
• Technical leadership of team in projects, design discussions and implementations
• Mentoring senior and junior engineers
• Improving development, testing, monitoring and operational tools and processes
• Talking to customers and users, discovering their requirements and helping plan for building their next feature requirements
• Profiling and optimizing bidding machines at the JVM, Kernel, network and CPU levels
• Setting up and running experiments to improve stability and bidding performance across the stack

You Have...

• 8+ years experience creating high performance distributed software systems
• Experience delivering significant improvements in scale, runtime, cost, features or reliability under little supervision
• Excellent skills in distributed system and software design, concurrent algorithms, data structures and software engineering
• In depth understanding of Linux kernel internals, especially in terms of memory management, networking and performance
• Degree in a topic related to Computer Science, or equivalent experience
• Experience building large scale distributed systems in AWS and using tools such as Terraform, Docker, Kubernetes, or Spinnaker
