Job Description

Defense Unicorns is seeking a Senior AI Agentic Engineer to embed with a government team in Springfield, VA (onsite). The role is focused on designing, integrating, and operationalizing AI agents and agentic workflows in secure enterprise environments, with emphasis on moving prototypes into production-ready, mission-relevant capabilities.

Responsibilities

Design, build, and integrate AI agents and multi-agent workflows using modern LLM and agentic technologies.
Develop agent capabilities that interact with enterprise applications, APIs, data sources, developer tools, and mission systems.
Integrate models, agents, tools, and enterprise data into secure workflows deployable in controlled and classified environments.
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.
Experience designing and implementing AI agents or agentic workflows.
Strong programming experience in Python and/or another modern programming language.
Experience integrating AI systems with APIs, enterprise applications, databases, and external tools.
Experience with one or more agent frameworks or orchestration approaches.
Working knowledge of RAG, embeddings, vector databases, tool/function calling, structured outputs, and prompt engineering.
Experience developing software in a Git-based, automated CI/CD environment.
Ability to rapidly prototype, test, troubleshoot, and iterate in ambiguous environments.
Strong understanding of software engineering fundamentals, including testing, version control, APIs, debugging, and system design.
Ability to work effectively alongside platform engineers, government personnel, and multiple technology vendors.

Experience taking AI prototypes into repeatable, production-ready capabilities.
Ability to evaluate new AI technologies quickly and make pragmatic build/buy/integrate decisions.

What Success Looks Like

Agentic capabilities move from prototype to mission use quickly, with working agents integrated into real government workflows.
Agents reliably connect to approved enterprise data, tools, and services, with appropriate identity, permissions, guardrails, and human-in-the-loop controls.
AI capabilities are measurable and trustworthy, with repeatable evaluation methods for accuracy, reliability, task completion, security, and operational performance.
Reusable agent patterns emerge, reducing engineering effort required to build and deploy the next agent or AI-enabled workflow.
AI integrates cleanly with the broader platform architecture across data, DevSecOps, Kubernetes/OpenShift, model, and application layers.
The engineer acts as a trusted AI technical advisor, identifying where agentic technology can create mission value and where it is not the right solution.
