Software Engineer - ML, Creative Optimization Ads

This is a founding ML engineering role focused on building the engine behind AI-generated ad creative for a new product. You will fine-tune vision-language models using state-of-the-art methods (e.g., LoRA) to produce high-quality video and image ads. Translate ad effectiveness into quantitative signals and define a metrics suite including offline metrics (FID, CLIP) and online metrics (CTR, ROAS). Build scalable ML-driven APIs and backend systems that leverage real-time performance data and feedback loops to continuously improve model output. Design, run, and analyze A/B experiments in a marketplace setting to validate optimization strategies. You will own key architecture decisions, collaborate with research and engineering teams, and deploy models on cloud platforms using Docker, Kubernetes, and Python.
