WHAT YOU'LL DO

SIXGEN is actively seeking candidates to be part of a team that supports the United States Cyber Command (USCC). Our team is standing up USCYBERCOM’s AI Enterprise capability — the central hub that mission teams turn to when they want to move an AI solution from prototype to a secure, governed, enterprise-scale service. As a AI/ML Engineer on this team, you will design and integrate the models, agents, and AI workflows that run on that platform, with significant, visible impact on the mission of the USCC.

WHAT

YOU'LL BE DOING

Provide embedded operations support, capability integration, and rapid prototyping for AI/ML-enabled tools in support of our customer.

Design and integrate LLM/agent orchestration workflows using agentic frameworks such as Lang Graph, Agno, and the NVIDIA NeMo Agent Toolkit.

Tune model gateway routing logic to select, evaluate, and optimize across multiple frontier and open-weight models for cost, performance, and mission fit.

Develop and integrate RAG pipelines, vector databases, and memory services to give agents access to mission knowledge and context.

Implement MCP (Model Context Protocol)-based tool-broker integrations so agents can safely and securely access enterprise tools and data.

Evaluate, benchmark, and tune models and agent behaviors; build automated evaluation pipelines to track quality, safety, and performance over time.

Partner with data scientists and mission analysts to translate research and prototypes into production-grade AI capabilities for the command.

Implement AI governance guardrails — content/safety filters, policy enforcement, and approval gates — for agentic workflows, and document model/agent architectures and evaluation results for reuse.

Research and evaluate emerging LLM, agent, and AI tooling to keep the command's AI capability current and adaptable.

REQUIREMENTS

Bachelor’s degree from an accredited college or university in Computer Science, Data Science, or a related discipline and 10+ years of experience; 4 additional years of experience may be considered in lieu of degree

Active TS/SCI clearance w/Poly

Advanced proficiency in Python for AI/ML application development

Demonstrated experience building or integrating LLM/agent-based systems in production

Experience with retrieval-augmented generation (RAG), vector databases, and prompt/context engineering

Ability to manage competing priorities in fast-paced mission environments and identify/escalate operational risks early

PREFERENCE TO CANDIDATES THAT HAVE

Master's degree and 8+ years of relevant experience

Experience supporting USCYBERCOM, NSA, DoD cyber operations, or related mission environments

Experience with frameworks such as Lang Graph, Agno, or the NVIDIA NeMo Agent Toolkit

Experience with model inference/serving platforms (NVIDIA NIM, vLLM, Ollama, LiteLLM)

Experience with MCP (Model Context Protocol) or similar tool-broker/integration standards

Experience with AI evaluation frameworks, model benchmarking, and observability (logs/metrics/traces) for AI workloads

Experience supporting USCYBERCOM, NSA, or DoD AI/cyber mission environments
