Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Staff engineer you will work on Singularity Marketplace - multi-tenant, event-driven platform that enables third-party integration applications to safely deploy, execute, and stream data across our AI SIEM ecosystem. You'll help build the next version of the Marketplace Catalog - the front door for every third-party integration our customers discover, evaluate, and install. You'll have the opportunity to build products using cutting-edge AI-native development practices that accelerate velocity while maintaining enterprise security standards. You'll be re-thinking how partners publish and version their applications, how customers browse and trust what they find, and the APIs and services that make discovery fast and reliable at scale. You'll integrate AI throughout the development lifecycle - augmenting design, code generation, testing, and security practices to increase velocity while maintaining the highest standards of code quality and security.
