AI Ingestion & Integration Hooks: Develop clean API endpoints, webhook receivers, and data ingestion hooks to collect, route, and inspect LLM prompts, context payloads, and agent execution logs. AI Gateways & Agent Workflows: Build middleware logic and AI Gateway integrations connecting model providers and agentic frameworks (LangChain, LlamaIndex, MCP) with inline security controls, policy enforcement, and fallback routing. Solution Architecture & Blueprints: Author technical architecture diagrams and integration blueprints documenting insertion points for the Prisma AIRS portfolio (Model, Red Teaming, Runtime, and Agent Security) within cloud and hybrid environments. Automated Red-Teaming & API Exposure : Engineer programmatic execution pipelines for automated LLM probing (jailbreaks, prompt injections) and expose structured API endpoints to serve telemetry data to frontend dashboards and SIEM tools. Technical Onboarding: Review partner software architecture and provide documentation or SDKs to speed up integration timeline Travel: This role may require travel Qualifications Required Qualifications Experience: 5+ years in Software Engineering or Systems Integration with a primary emphasis on backend development and cloud security. Backend Python Depth: Production-level mastery of Python for asynchronous backend services, API frameworks (FastAPI, Flask, or gRPC), and microservice architectures. Core Software & API Development: Experience developing, debugging, and integrating enterprise APIs (REST, gRPC, WebSockets) and API gateways (e.g., Envoy, Kong). Data Transformation: Experience writing code to map, translate, and standardize mismatched data formats between systems. System Orchestration: Experience building robust middleware, webhooks, and retry logic to handle high-volume sync traffic and system failures. AI Stack Integration: Practical experience integrating LLM APIs, vector storage, and agentic protocols/frameworks (LangChain, LlamaIndex, MCP) via backend middleware. Architecture & Security: Proven ability to create technical architecture blueprints (e.g., Lucidchart) and secure AI workloads against prompt injection and model vulnerabilities. Rapid mastery of Prisma AIRS. Testing & Quality Assurance: Experience using testing frameworks (e.g., PyTest, unittest) and robust evaluation workflows for distributed systems. Communication: Excellent customer focus, collaboration and communication skills Education: BS/MS Computer Science, Computer Engineering, or related technical field or equivalent or equivalent military experience Preferred Qualifications Asynchronous Systems: Strong background in distributed task queues (e.g., Celery, Redis, RabbitMQ) and event-driven backend architectures. AI Security Expertise: Hands-on experience with automated AI red teaming, prompt defense tools, and securing Model Context Protocol (MCP) server interactions. Ecosystem Familiarity: Working knowledge of major enterprise platforms (e.g., ServiceNow, Databricks, Glean) #LI-TD12 Compensation Disclosure The compensation offered for this position will depend on qualifications, experience, and work location.
