Job Summary

• As a Graph Database Engineer, you will lead the design, implementation, and optimization of graph database solutions that power mission-critical intelligence applications
• You will architect graphs that model complex relationships within data, enabling advanced analytics, pattern recognition, and discovery capabilities that traditional databases cannot support
• Your expertise will drive the development of graph-based applications that reveal hidden connections and deliver actionable insights to analysts and decision-makers
• You'll work across teams to translate domain knowledge into effective graph schemas, develop high-performance queries, and build intuitive interfaces that make complex relational data accessible
• This role requires a unique blend of database expertise, software development skills, and an understanding of how to represent and analyze connected data

Primary Responsibilities

• Design and implement graph data models based on domain requirements
• Develop efficient graph queries and algorithms to extract insights from connected data
• Build applications that leverage graph database capabilities for relationship analysis
• Optimize graph database performance and scalability
• Collaborate with data engineers to integrate graph databases with other data sources
• Participate in architectural design discussions for graph-based systems
• Evaluate and recommend graph technologies based on project requirements
• Document graph schemas, queries, and application architectures
• Provide guidance on best practices for graph data modeling and querying
• Consider performance trade-offs of various graph modeling approaches and contribute to technical decision-making

Required Qualifications

• Graph Theory Fundamentals: Strong understanding of graph theory concepts including nodes, edges, properties, traversals, and relationship patterns essential for effective graph database design
• Graph Query Language Proficiency: Demonstrated expertise in one or more graph query languages such as Cypher (Neo4j), Gremlin (Apache TinkerPop), SPARQL, or GraphQL for complex data retrieval and manipulation
• Advanced Graph Data Modeling: Experience translating business requirements into optimized graph schemas, including property graphs, RDF triples, or knowledge graph ontologies
• Graph Algorithm Implementation: Practical experience applying graph algorithms (e.g., path finding, centrality measures, community detection, similarity calculations) to solve complex analytical problems
• Graph Database Architecture: Experience designing, deploying, and administering production graph database systems with consideration for scalability, availability, and security requirements
• ACID Transaction Management: Understanding of transaction principles in graph databases, including consistency models, isolation levels, and techniques for maintaining data integrity in concurrent environments
• Graph Visualization Development: Experience implementing interactive graph visualization solutions using tools such as D3.js, Gephi, KeyLines, or similar technologies to communicate complex relationships effectively
• Performance Optimization: Demonstrated ability to tune graph queries, optimize indexes, leverage caching strategies, and implement database-specific best practices to improve query performance
• System Integration: Experience integrating graph databases with other data systems and applications through APIs, ETL pipelines, event streaming, or microservices architectures
• Data Migration and ETL: Proficiency in designing and implementing processes for importing, transforming, and exporting data between various formats and graph database environments, including handling large-scale data sets

Desired Qualifications

• Familiarity and experience with the Intelligence Community (IC), and the intel cycle
• Ability to be on-site 60% of the time at a client SCIF located in Washington, D.C.
• Strong verbal and non-verbal communication skills
• Strong interpersonal skills, with the ability to work effectively in a team environment and build strong relationships with team members

Exempt hourly position. 11 paid holidays, minimum of 3 weeks PTO, company sponsored group medical plan, company paid dental, vision, life insurance, and STD/LTD plans. Salary is dependent upon the candidate's experience and qualifications.
