About the role
- You will set the technical direction, make the key modeling decisions, and stay hands-on throughout.
- You will be a senior technical point of contact with the customer - explaining trade-offs, managing expectations, and turning results into clear recommendations.
Responsibilities
- Own the technical strategy for a personalization program on a production recommendation/ranking system, making the architecture and modeling decisions and being accountable for the results.
Requirements
- Experience with Amazon Bedrock or comparable managed LLM platforms for production inference.
- Hands-on experience with segment- or cohort-based personalization, including measuring performance at the segment level rather than relying on aggregate metrics.
- Experience designing cold-start strategies for users or items with limited history.
Nice to have
- Strong track record taking ML models from experimentation to production, owning the offline-to-online validation story (ranking metrics, ablations, segment analysis, shadow testing, A/B readiness).
- Strong feature engineering on large behavioral datasets using the modern data stack (PySpark, SQL, distributed data lakes).
- Rigorous experimental methodology - hyperparameter optimization, bias correction, and a disciplined, hypothesis-driven approach to measuring true lift.
- Hands-on AWS experience across the ML lifecycle, and strong proficiency in Python.
- Experience personalizing ranking for marketplaces or consumer platforms at scale (e commerce, food delivery, media, or similar).
- MLOps maturity: model versioning, monitoring, and reproducible training pipelines.
- Prior experience in a client-facing consulting or professional-services delivery environment.
Company info
- We are hiring an AI Engineer to be the lead technical contributor on a personalization and ranking engagement for a large-scale consumer marketplace.
