What you'll do
Design, build, and deploy large-scale ML systems for ad ranking, click-through and conversion prediction, bid optimization, and next-best-action recommendation.
Build and operate production ML pipelines — feature engineering, distributed training, deployment, retraining, and monitoring — that process billions of events and serve predictions at low latency.
Leverage the data assets from across the DT product portfolio to enable ML solutions that create decisioning in real time using the entire breadth of available features.
Optimize training and inference for compute efficiency (CPU/GPU utilization), latency, and cost across distributed systems.
Partner closely with Data Science, Data Engineering, and product teams to ship models that move key business metrics, and run rigorous online experiments to validate impact.
Stay current with applied ML research and bring innovative techniques to advertising, ranking, and audience modeling.
What you'll bring
8+ years building and deploying ML systems in production at scale, ideally in AdTech, recommender systems, search/ranking, or real-time bidding.
Strong software-engineering fundamentals — data structures, algorithms, system design — and proficiency in Python (plus Java, Scala, or C++ a strong plus).
Hands-on experience with modern ML frameworks (PyTorch, TensorFlow, or JAX) and distributed data/compute systems (Spark, Beam/Dataflow, Flink, or similar).
Experience building robust ML pipelines: feature stores, data versioning, model monitoring, and automated retraining.
A record of shipping models that demonstrably improved product or business metrics (e.g., CTR, CVR, ROAS).
Master's or Ph.D. in CS, ML, or a related field, or equivalent practical experience.
Nice to have
Experience with real-time, low-latency model serving and online learning.
Familiarity with Databricks / Unity Catalog, semantic layers, or feature platforms.
Experience with LLMs and agentic systems applied to audience insight or optimization.
