• Prototype and benchmark MCP and A2A protocols to enable dynamic orchestration of multiple agents and tools
• Lead context engineering & prompt design for RAG and agentic workflows; create evaluation harnesses to measure accuracy, latency, and cost
• Build proof-of-concepts that embed AI throughout the software-development life-cycle (SDLC)—planning, coding, code review, testing, and release—to quantify productivity gains
• Research and validate AI-driven cybersecurity use-cases (e.g., threat-hunting copilots, real-time anomaly triage) and partner with product groups to harden prototypes for production.
• Instrument metrics pipelines that track developer and security-analyst outcomes to demonstrate ROI of AI initiatives
• Craft executive-level narratives, demos, and visualizations that clearly communicate innovation roadmaps, technical trade-offs, and business impact
• Mentor senior engineers and researchers; foster a culture of experimentation, responsible AI, and security-first thinking

Your Experience 

• 10+ years in software/ML engineering, with 2+ years leading applied Generative AI or LLM initiatives at scale.
• Proven expertise in: Large Language & Multimodal Models: fine-tuning, RAG, alignment, hallucination testing.
• Distributed systems & MLOps: containerized inference, model-versioning, feature stores.
• Programming: Python (required) plus one of Go, Java, Javascript.
• Cloud AI stacks (GCP Vertex, AWS SageMaker, Azure ML) and vector databases.
• Hands-on experience integrating AI into developer tooling (IDE plug-ins, CI/CD, observability dashboards).
• Deep understanding of cybersecurity concepts (attack vectors, threat intelligence, MITRE ATT&CK) and ability to translate them into AI features.
• Strong communication skills; comfortable presenting to VP/C-suite audiences and external conferences.
• B.S. or higher in CS, EE, Mathematics, or related field; M.S./Ph.D. preferred or equivalent military experience

The Team

You will join a small, fast-moving Innovation Team inside the CPO’s office that partners with Product Engineering, Unit 42 research, and Field CTOs to incubate breakthrough capabilities before scaling them company-wide.
