Senior Software Engineer - Platform Graph

What You’ll Do:

• Help design, build, test, and run the graph data platform and its supporting microservices in C#/.NET, in line with Delinea’s cloud and security architecture standards.

• Build with AI every day. We’re an AI-first team: we lean on AI coding assistants and agents to design, write, and review code, and we expect everyone to keep getting sharper with them.

• Design the graph data models and schemas, including node and edge types, traversal patterns, and query patterns, to answer security questions such as relationship mapping, access-path analysis, and impact analysis.

• Validate designs against scale and latency targets for systems containing hundreds of millions to billions of entities.

• Build and evolve the API layer that other product teams query, keeping complexity behind clean, versioned REST and GraphQL contracts.

What You’ll Need:

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.

• 5+ years of experience writing production software in C#/.NET, or a comparable backend language, and building microservices.

• Practical experience using AI coding tools such as Claude Code, GitHub Copilot, Cursor, or similar tools in production work, along with the judgment to use them effectively.

• Experience designing data models and schemas, with a solid understanding of query optimization and distributed-data consistency trade-offs.

• Experience building systems that run at large scale and an understanding of how connected, relationship-shaped data and graph traversals differ from traditional relational access patterns.

• Experience with relational and/or NoSQL databases such as Azure SQL, Cosmos DB, PostgreSQL, or MongoDB.

• Strong understanding of microservices and RESTful API design.

• Experience with Microsoft Azure, or another major cloud provider, as well as cloud-native deployments using Kubernetes and containers.

We’d Love to See:

• Experience with graph databases and query languages such as JanusGraph, Neo4j, Amazon Neptune, Apache TinkerPop/Gremlin, or Cypher.

• Experience with large-scale distributed NoSQL or wide-column databases, such as Apache Cassandra or ScyllaDB.

• Background in graph theory, graph algorithms, network analysis, or relationship analysis.

• Experience with database performance tuning, partitioning, sharding, replication, and high-availability systems.

• Familiarity with event-driven architectures, service meshes, and API gateways.

• Working knowledge of Zero Trust architectures and secure software lifecycle practices.

• Experience building data platforms that support AI/ML or analytics use cases, such as anomaly detection or risk scoring.
