Job summary

DEFCON AI is seeking a senior engineer to build and own the end-to-end record matching and entity resolution capabilities. You will design and implement blocking, candidate generation, scoring, clustering, and provenance so every decision is auditable and explainable.

This remote role may require travel to headquarters, customer sites, and partner facilities as needed. You will work on a team delivering AI-assisted workflows that surface critical insights and ensure defensible data relationships

Qualifications

• 5+ years of experience shipping production record matching or entity resolution.
• Ability to explain the matching tradeoffs you made, including how you handled false merges versus false splits.
• Strong Python and SQL, with demonstrated experience on large, messy, real-world data.
• Ability to explain a matching decision to a stakeholder who must defend it without understanding its internals.
• US Citizenship Required.
• Active US Secret clearance required to start.

Responsibilities

• 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.
• Own technical execution of the matching approach against the in-house design: the fixed reference dataset, candidate retrieval and final matching evaluated separately, and threshold recommendations with evidence for review.
• Document matching logic in enough detail to serve as an implementation reference for other engineers.
