Requirements
- Advanced degree in computer science or relevant engineering-related field or equivalent experience.
- 8+ years of software engineering experience, including 5+ years working on ads delivery systems.
- Extensive experience building and operating large-scale, low-latency backend systems using languages like Java, Go, or Scala.
- Deep familiarity with building or maintaining budget control systems, feedback loops, or spend-prediction algorithms.
- Proven experience building or scaling experimentation platforms, with a deep understanding of variance reduction, interference/network effects, and metric design in a marketplace context.
- A track record of working on "mission-critical" pipelines (like billing, payments, or clearinghouses) where data precision, idempotency, and fault tolerance are paramount.
- Experience or strong technical interest in building the backend workflows required to serve, scale, and store Generative AI models for creative asset generation.
- Proficiency with real-time stream processing (Kafka, Flink, or Spark) specifically applied to event-based charging and real-time performance feedback.
- A proven ability to lead complex, multi-quarter technical roadmaps and mentor senior engineers in a high-growth environment.
Responsibilities
- Design and optimize sophisticated pacing controllers (PID, probabilistic forecasting) to smooth advertiser spend across diverse time zones and traffic spikes, ensuring optimal delivery and marketplace stability.
- Lead the backend integration of Generative AI models (Diffusion, LLMs) to automate the creation of high-performing image and video assets tailored to specific campaign goals and formats.
- Build and scale the infrastructure for high-velocity experimentation, including A/B testing, switchback tests, and long-term holdouts to measure the impact of marketplace changes on advertiser ROI and platform health.
- Architect and maintain high-throughput billing pipelines that process billions of events with 100% accuracy, bridging the gap between real-time ad delivery and mission-critical financial reconciliation.
- Analyze complex financial and marketplace datasets to refine the trade-off between spend velocity and advertiser performance, using experimentation results to tune pacing and billing logic.
