  • Partner with cross-functional teams to drive technical innovation and maintain a high bar for system quality.
  • Analyze complex datasets and lead experimentation efforts to optimize performance metrics.

What we're looking for

  • Scalable Backend Experience: Proven experience building and operating large-scale distributed systems using languages like Java, Go, or Scala.
  • Ad-Tech Domain Knowledge: Proven experience in the ads delivery lifecycle, specifically with pacing controllers, auction mechanics, and delivery funnels.
  • Real-Time Data Processing: Deep familiarity with low-latency data pipelines and stream processing technologies like Kafka, Flink, or Spark.
  • Systems Optimization: Experience building or maintaining control systems, PID controllers, or bid/pricing optimization systems.
  • Analytical Mindset: Proficiency in metric design, experimentation methodologies, and using data to guide architectural decisions.
  • AI/Agentic Interest: (Plus) Experience or a strong interest in building infrastructure to support AI agents or LLM-integrated backend workflows.
