Senior Level, Lead/Staff
8+ years expAtlas is seeking a Senior Data & Ontology Engineer to design, build, and evolve canonical data models that represent identities, assets, entities, and their relationships across large, complex enterprise environments. This role is foundational to enabling reliable analytics, automation, and machine-learning–driven decision systems.
Management Consulting
Responsibilities
Design and maintain canonical data models representing identities, assets, systems, services, and their relationships
Define entity schemas that balance expressiveness, performance, and long-term maintainability
Establish modeling standards that enable consistent interpretation across analytics, automation, and ML systems
Explicitly model relationships, hierarchies, and associations rather than relying on implicit joins
Build and maintain entity resolution, aliasing, and normalization logic across multiple source systems
Handle ambiguous identity mappings, duplicates, and partial matches using defensible, explainable logic
Design mechanisms to maintain stable identifiers across system boundaries and over time
Ensure entity representations remain consistent as source systems and attributes change
Partner with data engineering teams to implement ingestion and transformation pipelines that preserve semantic meaning
Ensure data models support both batch and near-real-time use cases
Collaborate with platform and automation engineers to enable operational data consumption
Identify, troubleshoot, and remediate data quality issues that impact downstream reasoning or automation
Collaborate with ML engineers to ensure data models are consumable by decision and classification systems
Define features and representations that preserve entity context and behavioral meaning
Assess how modeling decisions impact model accuracy, confidence, and stability
Iterate on models as decision systems mature and requirements evolve
Document schemas, relationships, assumptions, and modeling tradeoffs clearly and thoroughly
Establish processes to evolve data models without breaking downstream dependencies
Participate in architectural reviews and long-term data strategy discussions
Serve as a technical authority on entity modeling and semantic data design
Qualification
Required
Bachelor's or Master's degree in Computer Science or a related technical field
8+ years of experience in data modeling, data engineering, or schema design roles
Proven experience designing data models for complex, multi-source enterprise systems
Strong understanding of identity modeling, entity relationships, and normalization strategies
Ability to reason through ambiguity, inconsistency, and edge cases in real-world data
Preferred
Experience with ontologies, knowledge graphs, or semantic data models
Experience supporting machine learning or automated decision systems
Familiarity with graph-oriented or relationship-centric data representations
Background working in security, identity, or large-scale enterprise platforms
