Job Level

About the role

  • Develop and deploy enterprise-scale agentic AI systems, including Multi-Agent and Agent-to-Agent (A2A) workflows, leveraging common industry standards, such as the Model Context Protocol (MCP), to create interoperable and scalable AI agents.
  • Implement robust MCP Tools and Resources to securely expose data and functionality, enabling LLMs to interact with internal systems and APIs in a standardized way.
  • Contribute to the architecture and implementation of a centralized 'AI Gateway' to ensure platform independence, Large Language Model (LLM) agnostism, and provide a unified interface for leveraging various LLMs.
  • Implement and manage robust observability pipelines to track trace-level data, monitor model latency, and optimize the cost and performance of Generative AI systems in production.
  • Collaborate closely with principal engineers, data scientists, and systems architects to translate strategic designs into hardened, production-grade solutions.
  • Implement and maintain robust AI guardrails to filter inputs and outputs, preventing data leakage (both into unsecure systems and future LLMs), prompt injection, and other adversarial attacks.
  • Apply and promote software engineering best practices, including robust version control, comprehensive automated testing, and mature CI/CD processes for AI systems.
  • Stay current with industry trends in agentic AI, operational AI, and MLOps to continuously evolve the team's capabilities and technical implementation.

Requirements

  • A Bachelor's degree in Computer Science, Engineering, or a related quantitative field with 12+ years of professional experience, or a Master's degree with 10+ years of relevant experience.
  • Demonstrated programming proficiency in Python and hands-on experience with major ML libraries and frameworks (e.g., TensorFlow, PyTorch, Scikit-learn).
  • Hands-on experience implementing solutions using the Model Context Protocol (MCP) to build standardized tools and data sources for LLM applications.
  • Experience with software engineering best practices and tools, including version control, automated testing, and CI/CD pipelines.
  • Solid understanding of the full machine learning lifecycle, from data preparation and model training to deployment and monitoring.
  • A strong understanding of agentic AI patterns, multi-agent systems, and LLM-based workflows.
  • An understanding of cybersecurity principles as they apply to AI systems, including threat modeling and vulnerability assessment.
  • Must be a U.S. Citizen and have the ability to obtain and maintain a U.S. security clearance.
