Description

Astrix Security protects organizations from identity-based attacks through AI agents and non-human identities that operate autonomously across cloud and SaaS environments. We're looking for a Senior Backend Engineer to architect and build the backend foundation of our AI agent security platform: designing the core systems that discover, model, and secure machine identities that outnumber humans 10:1 in enterprise environments yet remain largely invisible to traditional security tools. About the role Design and implement backend services for discovering and inventorying AI agents, autonomous systems, and non-human identities across AWS, GCP, Azure, and 30+ SaaS platforms Investigate emerging AI agent frameworks and platforms (LangChain, AutoGPT, enterprise AI tools) to stay ahead of the threat landscape and build integrations before they become attack vectors Unify disparate identity and permission models from dozens of platforms into a cohesive security data model that enables cross-platform risk analysis. prototype novel approaches to AI agent behavior analysis - you'll be exploring detection methods that don't exist yet, from behavioral fingerprinting to anomaly detection for autonomous systems Architect scalable ingestion pipelines that process millions of events daily to track AI agent behavior and detect anomalies. Develop APIs and services for monitoring AI agent risk, analyzing behavior patterns, and automated remediation workflows. Make critical architectural decisions on data models, service boundaries, and scaling approaches. Work directly with product, core team and application team, security research to turn customer security challenges into platform capabilities. Requirements 5+ years building production backend systems, with experience in security, identity/IAM, cloud infrastructure, or related domains Strong proficiency in backend languages (Preferably Python or TypeScript) with a track record of shipping production code Proven ability to design and own complex backend systems end-to-end, especially systems involving high-cardinality data, authorization modeling, or multi-tenant architectures. You've designed data models for relationship graphs, security entities, or permission hierarchies. Deep understanding of identity and permission systems with strong technical curiosity: you can analyze new platforms to understand their identity models and API behaviors, and you're capable figuring out security implications in systems without established patterns Experience with cloud provider APIs (AWS IAM, GCP IAM, Azure AD) or the ability to master them quickly through documentation and experimentation Data modeling expertise: you've designed schemas for relationship graphs, security entities, permission hierarchies, or other complex domain models Ownership mindset: you take end-to-end responsibility for what you build and follow through from design to production

Responsibilities

The Senior Backend Engineer will design and implement backend services for discovering AI agents and non-human identities across various platforms. They will also architect scalable ingestion pipelines and develop APIs for monitoring AI agent risk and behavior analysis.
