Principal Engineer

Who you are

• Extensive experience architecting large-scale, data-intensive systems (streaming/batch pipelines, distributed data stores, or audience/measurement platforms)
• A track record of technical leadership at scale without direct reports — driving alignment across teams through influence and design rigor
• Strong system design fundamentals: data modeling, distributed systems tradeoffs, scalability and reliability patterns
• Strong cross-functional communication skills, with experience partnering across product, data science, and multiple engineering teams
• Comfortable operating with significant ambiguity and defining technical direction where none currently exists
• Ad tech or adjacent industry experience
• Experience with data clean rooms — clean room-based collaboration is an area we expect to grow significantly within measurement
• Background working across multiple time zones or with globally distributed engineering teams

What the job involves

• As a Principal Engineer, you will own architecture and system design across our Audiences and Measurement product lines.
• These two systems currently evolve somewhat independently, and this role exists to bring them into architectural alignment — shared data models, consistent pipelines, and a unified approach to how we ingest, process, and activate viewership and audience data at scale
• You'll set technical direction across teams rather than within one, and act as a thought partner to engineering leadership on the hardest design problems we have
• Set architectural direction and technical standards across measurement and audience systems, ensuring they scale reliably and remain extensible as new data sources and products come online
• Lead system design for high-impact, cross-team initiatives, balancing near-term delivery with long-term platform health
• Drive architectural convergence between audiences/segments and measurement so they function as one cohesive system
• Help define our technical approach to data clean room integrations, as measurement partnerships increasingly require privacy-safe data collaboration
• Act as a technical thought partner to engineering leadership, raising the bar on design rigor, code quality, and operational excellence
• Mentor senior and staff-level engineers, and drive alignment on architecture across teams that own adjacent parts of the measurement/audiences stack
• Identify and de-risk technical debt, scalability bottlenecks, and single points of failure before they become organizational blockers
