## About the role

This role sits in one of the most critical parts of the platform: determining when records from dozens of disparate sources represent the same real-world entity. Graph design and matching strategy are developed in-house, and you’ll be the engineer who turns those concepts into production-ready capability. You’ll shape implementation details, but this is first and foremost a builder role. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Implement and refine entity-level record matching: blocking, candidate generation, pairwise scoring, clustering, and threshold policy
- Reuse one matching engine for record linkage, deduplication, and known-entity checks
- Establish provenance so every node and edge traces back to the source that asserted it
- Own the false-merge versus false-split tradeoff in matching decisions and make it explainable
- Document matching logic in enough detail to serve as an implementation reference for other engineers
- 5+ years of experience, including shipping production record matching or entity resolution
