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.
