About the Role
Join an AI-powered creative advertising company as a full-time technical co-founder and own its technical and research direction. You will develop a proprietary platform for training and evaluating creative AI, building on existing product workflows and real-world feedback.
What You'll Do
-
Set technical and research strategy, from current workflows through the development of a training and evaluation platform.
-
Build data infrastructure connecting creative briefs, submissions, generation traces, decisions, critique, and campaign outcomes.
-
Develop systems to evaluate, rank, critique, generate, and improve creative work.
-
Design allocation policies that direct campaign budgets and support useful data collection.
-
Make decisions about frontier models, fine-tuning, post-training, reinforcement learning, and original research.
-
Build reliable production infrastructure for creative workflows, experimentation, training, and inference.
-
Set standards for data quality, consent, privacy, measurement, and model evaluation.
-
Recruit and lead the first engineering and research team, and work directly with creators and brands.
What We're Looking For
-
Typically 3 to 20 years of relevant experience, with hands-on experience building preference or reward models, RLHF, ranking, or evaluation systems.
-
Experience applying causal inference to observational data, including selection bias, counterfactual or off-policy evaluation, and adaptive experimentation.
-
Have shipped products or features used by people and worked on production ML tied to business outcomes, such as ads, marketplaces, recommenders, or ranking.
-
Strong Python and production ML infrastructure experience, plus ownership of a model, evaluation, or infrastructure program end to end.
-
Experience with noisy, delayed, or subjective outcomes; bandits, sequential allocation, multimodal systems, or agents is valued.
-
Track record recruiting and leading technical talent, and willingness to commit full-time as an equal co-founder in an early-stage environment.
