About this role

Principal Software Engineer - PubMatic AgenticOS (Buy Side Bidding Platform) Redwood City, US About the Role We are seeking an experienced Principal Software Engineer - PubMatic AgenticOS to lead the design and development of highly scalable, low-latency buy-side ad tech systems. This role is ideal for someone with deep expertise in Golang, real-time bidding systems, and campaign pacing and optimization algorithms, with strong exposure to DSP / performance advertising domains. As a technical leader, you will own critical components of the bidding and optimization stack, influence system architecture, mentor senior and junior engineers, and work closely with product, ML, and data teams to drive measurable performance outcomes across large-scale advertising campaigns. What You'll Do Architect, design, and build high-throughput, ultra-low-latency real-time bidding systems for buy-side advertising platforms. Lead development of bidder services handling millions of QPS with strict latency and reliability SLAs using Golang/C/C++. Design and implement campaign pacing, budget management, and delivery optimization algorithms across multiple objectives (CPA, ROAS, CTR, CVR). Own core systems for deal execution, auction participation, bid shading, and supply path optimization. Build and evolve real-time and near-real-time data pipelines for impressions, clicks, conversions, and attribution using Kafka, Flink, or Spark. Collaborate closely with ML engineers to productionize models such as bid optimization, contextual bandits, reach forecasting, and incrementality models. Integrate and maintain support for programmatic advertising protocols (OpenRTB, VAST, CTV-specific standards). Drive architectural decisions around scalability, fault tolerance, data consistency, and latency optimization. Ensure data quality, governance, privacy, and compliance across the performance advertising stack.
