About the Role

Join a small, early-stage team building an advertising technology platform. As Founding Engineer, you will own and develop the production recommendation system, with impact across data, machine learning, and real-time ad delivery.

Responsibilities

  • Design and ship a low-latency ad ranking system that selects campaigns and creative for each opportunity while balancing advertiser performance and user experience.
  • Build data pipelines and feature infrastructure for ongoing model training across signals such as clicks, installs, and conversions.
  • Model user behavior and context using engagement history, conversational data, and signals such as geography, device, and session activity.
  • Develop efficient ad-serving infrastructure designed for sub-second latency and cost-conscious operation.
  • Build generative agents that create playable and video ad variants, and feed their performance back into the recommendation system.

Requirements

  • Typically 0 to 3 years of experience, with demonstrated ability to own substantial engineering work.
  • Experience shipping an ML or AI system to production, ideally owning the full path from data pipelines and model training through serving.
  • Strong backend, data infrastructure, and production serving skills, including experience with systems operating at significant scale.
  • Ability to reason from first principles and work across infrastructure, classical machine learning, and AI agents.
  • Experience with recommendation systems, ranking, advertising technology, or consumer products is useful.
  • Gaming interest and experience with playable ads are also valued.
  • PyTorch experience and an active GitHub profile or shipped side projects demonstrating technical work are welcome.
  • Must be a U.S. citizen or permanent resident.
  • Must be able to work on-site in San Francisco five days per week.
