- Work with LLMs, RAG, embeddings, vector databases, tool/function calling, structured outputs, MCP, and related technologies.
- Develop mechanisms for agents to securely discover, access, reason over, and act upon approved enterprise data and services.
- Prototype and rapidly evaluate emerging models, agent frameworks, and AI capabilities to identify measurable mission or engineering value.
- Develop evaluation and testing frameworks for agent accuracy, reliability, safety, latency, cost, and task completion.
- Implement guardrails and policy controls governing agent behavior, tool access, data access, and human approval points.
- Integrate agentic capabilities with CI/CD and DevSecOps workflows to support repeatable development, testing, deployment, and lifecycle management.
- Collaborate with platform engineers to operationalize AI workloads within Kubernetes/OpenShift environments.
- Work with commercial AI and technology partners to integrate their capabilities into the broader engineering ecosystem.
- Troubleshoot issues across models, agent frameworks, APIs, data sources, networking, identity, and infrastructure.
- Develop reusable patterns for agent deployment, configuration, observability, evaluation, and lifecycle management.
- Document architectures, integration patterns, agent specifications, evaluation results, and operational procedures.
- Identify recurring AI engineering challenges that can be standardized, automated, or productized into reusable capabilities.
- Stay current with rapidly evolving agentic AI technologies and assess their applicability to secure government environments.
Requirements
- Active Top Secret clearance.
- Hands-on experience building applications or systems using large language models and generative AI.
