You'll work at the intersection of identity, platform reliability, and developer experience, solving problems that have direct impact on every engineer and every customer at KnowBe4.. . The identity and auth platform you'll help lead underpins session management, single sign-on, user provisioning, and cross-product authorization for the entire KnowBe4 product suite. The decisions made here ripple across every engineering team at KnowBe4 and the end-user sessions of a global customer base. We need engineers who can think at that scale, communicate across organizational boundaries, and write production-quality code — not just direct others to.. . This is a technical individual contributor role. You'll lead through your engineering, your judgment, and your ability to bring others along with you.. . What You'll Build. . . Session and identity APIs in Rust deployed as AWS Lambda functions — high-throughput, low-latency services handling JWT validation, session lifecycle, and encrypted token management across multiple AWS regions. . Identity provider integrations — orchestration and configuration of Auth0 and Keycloak tenants, IDP sync services, and SSO/OIDC broker logic that spans legacy and modern auth systems. . User provisioning and lifecycle services — the USPS (User Provisioning Service) and UPMS (User Permission Management Service) layers that synchronize user state across products, CRM systems, and identity stores. . Cross-team platform SDKs — auth libraries in Rust, C#, and TypeScript consumed by multiple engineering teams; these are the APIs that teams depend on, so design quality and backward compatibility matter deeply. . Distributed event infrastructure — DFS (Distributed Feedback Service) subscribers, SQS-based event pipelines, and the message routing layer that coordinates state changes across bounded contexts. . Infrastructure-as-Code at scale — multi-account, multi-region Terraform that provisions and governs the identity and platform layer across development, staging, and production environments. .
