About the role

About the Role

Join an early-stage advertising technology team building real-time ad recommendations for interactive AI and gaming experiences. As a founding engineer, you will own core systems spanning data, machine learning, and production serving, helping shape how ads are selected and personalized at scale.

What You'll Do

  • Design and ship low-latency retrieval, ranking, and reranking systems that select campaigns and creatives while balancing advertiser performance with user experience.
  • Build data pipelines and feature infrastructure for continuous model training across clicks, installs, and conversions.
  • Develop user and context representations using engagement history, conversational signals, and session context.
  • Build cost-efficient serving infrastructure that delivers ads with sub-second latency.
  • Create generative agents that produce playable and video ad variations and feed performance signals back into recommendations.

What We're Looking For

  • Early-career experience, with 0 to 3 years in software engineering, machine learning, or a related area.
  • Experience shipping at least one machine learning or AI system to production.
  • Ability to build data architecture, feature pipelines, and serving infrastructure end to end, beyond model development alone.
  • Experience with recommendation systems, ranking, or advertising technology, and familiarity with PyTorch.
  • Strong backend, machine learning, and infrastructure skills, demonstrated through shipped work or active projects.
  • Startup experience, initiative, and comfort owning ambiguous problems; mentoring or leading other engineers is a plus.
  • Interest in gaming, including experience with mobile games, reward ads, or game development such as HTML5 or playable builds.

Compensation & Benefits

Base salary: $200,000 to $250,000 annually. Visa sponsorship is not available.

Location

On-site in San Francisco, California, five days per week.
