  • 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).

  • 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

Other

  • 10+ years in software/ML engineering, with 2+ years leading applied Generative AI or LLM initiatives at scale.
  • B.S. or higher in CS, EE, Mathematics, or related field; M.S./Ph.D. preferred or equivalent military experience
