We’re building a new, large-scale distributed graph data platform that maps how identities, accounts, and the resources they can access connect to one another, and makes those connections fast to query for the products that build on top of us. As a Senior Software Engineer, you’ll help design and build the platform from the ground up: the graph data models and schemas, the distributed-systems decisions that have to hold up at hundreds of millions to billions of entities, and the cloud-native services and APIs that other teams query. You’ll work in C#/.NET on Microsoft Azure and deploy through Kubernetes. You’ll report to the team’s Engineering Manager. What You’ll Do: • Help design, build, test, and run the graph data platform and its supporting microservice s 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.
