Job Description: HPE’s Cybersecurity team is seeking a Lead Agentic AI Engineer to design, enhance and support  the technical direction of our AI-Enabled Offensive  security organization. Using your expertise in offensive security, you will architect and deliver secure, reliable, production-grade agentic AI platforms. These platforms will accelerate and scale cybersecurity triage, investigation, detection engineering, response, and other complex workflows. Primary Responsibilities • Own the reference architecture and engineering standards for production agentic AI systems. • Design reusable agent execution harnesses that separate AI reasoning and planning from deterministic execution. • Lead multi-agent workflows, state management, memory, tool calling, human-in-the-loop controls, and long-running processes. • Define model-agnostic interfaces supporting commercial, cloud-hosted, and open-weight models, including routing, fallback, and workload-based selection. • Architect retrieval, context, and memory services using technologies such as RAG, hybrid search, and vector databases. • Establish strategies for MCP servers, A2A protocols, APIs, tool registries, and enterprise integrations. • Define evaluation, observability, reliability, and security practices, including least privilege, sandboxing, authorization, secrets management, guardrails, auditability, and defenses against prompt injection, tool abuse, and data leakage. • Lead cross-functional architecture decisions, mentor engineers, and communicate technical tradeoffs to senior leadership. Experience and Skills • Candidates should demonstrate deep expertise in at least three areas, with Agentic Systems & Harness Engineering required: • System Design & Architecture • Agentic Systems & Harness Engineering • Model-Agnostic AI & Context Engineering • Platform Engineering & Production Reliability • Evaluation, Security & AI Safety • Experience with cybersecurity automation, security operations, offensive security, adversary simulation, reusable agent platforms, open-weight inference, or frameworks such as OWASP Top 10 for LLM Applications, MITRE ATLAS, MITRE ATT&CK, and NIST AI RMF is preferred. • 10+ years of experience in software, platform, distributed-systems, or AI engineering, with demonstrated technical leadership on production systems. • Proven experience architecting and operating production LLM-powered or agentic systems across their full lifecycle. • Deep expertise in distributed systems, microservices, APIs, event-driven architectures, workflow and state management, scalability, concurrency, and fault tolerance. • Strong hands-on experience with agent orchestration, planning, tool calling, delegation, memory, and long-running workflows using LangGraph, Claude Agent SDK, Semantic Kernel, AutoGen, or equivalent. • Experience with foundation-model APIs and open-weight or self-hosted models,
