At Quantcast, we don't just build advertising technology, we revolutionize how it works. Our AI-powered Demand Side Platform (DSP) connects the world's most ambitious marketers with their ideal audiences across the open internet, delivering results that actually move the needle. Since 2006, we've been the industry's trailblazer, launching the first AI-powered measurement platform for publishers and the first AI-driven DSP. Our AI doesn't just optimize—it delivers the measurable outcomes that matter most to our clients, giving them the competitive edge they need in a crowded marketplace. Ready to join the team that's defining the future of digital advertising?

We’re looking for a Senior Software Engineer to join our Partner Integrations team. The team acts as a bridge between Quantcast and the third parties that are needed to achieve our customers’ advertising goals. The team is responsible for bringing all the available ad opportunities on the open internet to our platform, managing the entire lifecycle of all the creatives as well as ingestion of customer segments from data platforms. 

We are only able to achieve all this by working closely with our partners and the high volume live integrations that we have built with them over time. Our systems range from monoliths to microservices, all hosted in AWS along with a large swathe of data pipelines that ship several Terabytes of data everyday. We are responsible for the evolution and continuing operational excellence of these systems that ultimately enable smooth running of ad campaigns on the Quantcast platform.

  • Drive engineering initiatives through design, implementation and production rollout, ensuring systems are reliable, monitored, and successfully adopted by users.

  • Identify and resolve cross-team technical and commercial bottlenecks, coordinating with wider engineering teams, other functions as well as with our 3rd party partners to ensure project’s success.

  • Support the professional development of your peers and junior members of the team by providing regular, constructive feedback on code, system design, and engineering processes.

  • Manage the resolution of complex on-call incidents, coordinating team-wide responses and implementing measures to improve long-term system health.
  • Focus on outcomes: You don’t claim victory at code completion; you measure success by positive business results and customer adoption.

  • Operate with autonomy: You are comfortable taking high-level priorities and turning them into actionable, well-defined technical roadmaps without constant supervision.

  • Bridge the gap: You enjoy deeply understanding the end-customer use case and translating those requirements into robust technical solutions.

  • Advocate for excellence: You have a passion for mentoring others and are dedicated to maintaining high standards for code quality and operational reliability.

  • You have at least 2 years of experience building and maintaining complex, high-scale distributed systems.

  • You have a degree in Computer Science or an adjacent field.

  • You can effectively distill complex technical updates into clear, actionable information for both technical and non-technical audiences.

  • You excel at working across team boundaries and with third parties to untangle dependencies and move projects forward.

  • You have a deep understanding of observability and what it takes to keep mission-critical systems running in a high-velocity production environment.

  • You are proficient in Java or a similar modern programming language, along with a deep understanding of how to leverage it to build and scale high-performance systems.
