Lead Agentic AI Offensive Security Engineer

This role has been designed as ‘Hybrid’ with a requirement that you will work on average 2 days per week from an HPE office., 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.

• 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, structured generation, and function calling.
• Expert Python and backend engineering skills, including REST/gRPC, messaging, Docker, Kubernetes, CI/CD, and cloud infrastructure.
• Practical experience with agent evaluation, trajectory and regression testing, AI security, and production reliability.
