Job Description

Blend is looking for an Identity / MDM Specialist to architect and implement the foundational layer that makes intelligent, data-driven decisions possible. This is a high-impact engineering role at the heart of our data platform you will design how customer identities are resolved, how households are linked, and how golden records are maintained across a complex multi-source environment.

If you have deep experience untangling messy, real-world identity data and a track record of building matching systems that actually work at scale, this role was designed for you.

Identity Resolution

• Design and implement customer matching logic using both deterministic and probabilistic approaches
• Build a household linkage model that connects individual subscribers to household units
• Implement deduplication logic across multiple heterogeneous data sources
• Define golden record structure, confidence scoring, and merge/split rules

Data Quality & Governance

• Establish data quality frameworks and monitoring to ensure identity integrity over time
• Define PII handling standards, lineage tracking, and audit trails for all identity data
• Develop confidence thresholds and escalation paths for low-confidence matches

Vendor & Stakeholder Coordination

• Coordinate with third-party identity enrichment vendors on data formats and matching keys
• Partner with product, engineering, and analytics teams to align on unified customer definitions
• Document architecture decisions, match rules, and operational runbooks

Qualifications

• 8+ years in data engineering with at least 4 years focused on identity resolution or MDM
• Hands-on experience with MDM platforms and graph data models for entity resolution
• Proven track record building probabilistic matching algorithms in production environments
• Deep expertise in PII handling, data privacy compliance, and secure data practices
• Experience integrating third-party identity enrichment data (e.g. Acxiom, LiveRamp, or similar)

Technical Skills

• Identity resolution frameworks and MDM platforms (e.g. Informatica, Reltio, D&B MDM, or custom-built)
• Probabilistic matching: blocking strategies, similarity scoring, ML-assisted entity resolution
• Graph data models for household and relationship mapping
• Data quality tooling and profiling at scale
• SQL, Python, and distributed data processing (Spark, Databricks, or equivalent)

Soft Skills

• Ability to operate independently and make architectural decisions with limited oversight
• Strong written and verbal communication — you can explain a confidence score to a product manager
• Collaborative approach to cross-functional work with engineering, analytics, and vendors

Nice to Have

• Experience in media, telecommunications, or subscription-based product environments
• Familiarity with graph databases (Neo4j, Amazon Neptune) for relationship modeling
• Exposure to real-time identity resolution pipelines
• Experience building identity resolution on cloud-native stacks (AWS, GCP, Azure)
