Job description

At Quantcast, we're redefining what's possible in digital advertising. As a global Demand Side Platform (DSP) powered by AI, we help marketers connect with the right audiences and deliver measurable results across the Open Web. Our foundation is built on cutting-edge measurement and consumer analytics, giving our clients the tools they need to drive success in an ever-evolving digital landscape.

Since our start in 2006, we've pioneered industry firsts—from launching the original measurement platform for digital publishers to introducing the first AI-driven DSP. If you're ready to be part of a dynamic, forward-thinking team that thrives on creating transformative solutions, Quantcast is the perfect place to grow your career.

At Quantcast, we use technology to help brands and publishers understand, reach and influence the constantly-changing behaviors of consumers. The Real-Time Bidding (RTB) 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.

As a Senior Software Engineer with a focus on Platform Reliability, you care about the health and maintainability of our systems and the velocity of the engineering teams. You write code, design systems, build out proof of concepts, and compare and contrast technology alternatives that improve systems and automation throughout our products and tech stack. Working side-by-side with engineers, you will build and operate real-time high-scalable systems.

What you'll do:

• Design, code, test, and debug software applications and constantly improve large-scale global systems that respond to millions of real-time requests per second efficiently.
• Write clean, efficient, and maintainable code using industry best practices.
• Work and collaborate closely with cross-functional teams, including product engineering, modeling, and other platform teams, to ensure delivering high-quality software products.
• Participate in code reviews and provide constructive feedback to team members.
• Constantly improve development, testing, configuration management, monitoring, and operational tools and processes.
• Identify performance bottlenecks and optimize system components for enhanced scalability.
• Innovate with new designs and optimizations to improve the performance, elasticity, and fault-tolerance of existing infrastructure.
• Develop automation tools and scripts to streamline operational tasks and improve system reliability.
• Manage cloud-based infrastructure for RTB systems.

Who you are:

• Degree in a topic related to Computer Science, or equivalent (We recognize that knowledge and skills equivalent to those earned in a degree program can also be achieved via nontraditional paths, and welcomes applicants with nontraditional training.)
• 3+ years experience developing and working on distributed software systems as a Software Engineer, DevOps Engineer, Reliability Engineer, or Site-Reliability Engineer (SRE).
• 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.
• Hands-on experience with Java, Golang, or a similar language.
• Experience with cloud environments like AWS and using tools such as Ansible, Terraform, Docker, and Kubernetes is highly desirable.
• Experience in programmatic advertising, high-frequency trading, or similar high-volume, low-latency applications is highly desirable.

At Quantcast, we craft offers that reflect your unique skills, expertise, and geographic location. On top of a competitive salary, this position includes eligibility for a performance bonus, equity, and a comprehensive benefits package. Depending on your location, this may include generous vacation, medical, dental, and vision coverage, and retirement plans. For more details, visit our Careers page and see how we support our team.

Founded in 2006 and headquartered in San Francisco, we are a diverse, aligned community with offices across 10 countries worldwide. Join the team that unlocks potential.
