About the Job

Requirements

  • A bachelor's degree in a related technical field and at least 5 years of relevant experience are required; an additional 4 years of experience may substitute for the bachelor's degree.
  • At least 3 years of software development or data science experience, including 2 or more years focused on generative AI, large language models, or natural language processing.
  • Hands-on experience with foundation models including GPT-4, Claude, Gemini, Llama, and Mistral, covering prompt engineering, few-shot learning, fine-tuning, and API integration.
  • Strong Python skills and experience with LangChain, LlamaIndex, Hugging Face, and OpenAI or Anthropic APIs.
  • Experience building retrieval-augmented generation systems using vector databases such as Pinecone, Weaviate, ChromaDB, or pgvector.
  • Cloud experience with AWS or Azure and experience deploying AI or machine-learning models in production.
  • Understanding of AI safety, hallucination mitigation, bias reduction, and prompt-injection protection.
  • Experience with Git, continuous integration and continuous delivery, and DevSecOps practices.
  • U.S. citizenship is required.
  • Ability to obtain a final Top Secret/Sensitive Compartmented Information clearance with polygraph is required.
  • A current, valid U.S. passport is required for potential overseas travel.

Responsibilities

  • Design and optimize generative AI solutions using GPT-4/5, Claude, Gemini, and Azure OpenAI, including prompt engineering, fine-tuning, and retrieval-augmented generation.
  • Implement agentic large-language-model architectures with structured outputs such as JSON and GeoJSON, chain-of-thought or chain-of-debate methods, and multi-agent orchestration.
  • Build and maintain prompt libraries, evaluation frameworks, and quality-assurance pipelines for defense-grade AI content.
  • Integrate generative AI into existing platforms through documented APIs, ensuring interoperability with Department of Defense systems including Maven, C2IE, and IRIS.
  • Research emerging generative AI techniques, including multimodal models, synthetic data generation, and AI-assisted analysis for information operations.
  • Translate COCOM operational requirements into deployable AI solutions and support tabletop exercises and platform demonstrations.
  • Implement responsible AI practices including bias detection, validation, hallucination mitigation, and human-in-the-loop workflows.
  • Support minimum-viable-product-aligned milestone delivery, contributing to technology readiness level progression and return-on-investment measurement.
  • Document novel prompting techniques, model configurations, and workflows that may constitute intellectual property or trade secrets.

Desired Qualifications

  • A master's degree.
  • Experience with agentic AI architecture, multi-agent workflows, and large-language-model tool use.
  • Hands-on experience with fine-tuning, reinforcement learning from human feedback, direct preference optimization, LoRA, or QLoRA.
  • Familiarity with multimodal models and defense or intelligence applications.
  • Experience with IRIS, OMEGA, or similar operational platforms.
  • Background supporting information operations, psychological operations, influence analysis, or COCOM operations.
  • Knowledge of MLOps, A/B testing, and large-language-model evaluation frameworks such as RAGAS or DeepEval.
  • Experience with synthetic data generation, simulation, or Monte Carlo methods.
  • Understanding of geospatial data formats such as GeoJSON and KML, and visualization tools such as Plotly and D3.js.
  • Strong communication skills for translating technical information to nontechnical audiences and conducting customer demonstrations.
  • Relevant cloud or AI certifications from AWS, Azure, Google, or DeepLearning.AI.

About the Company

Peraton

Runs and secures technology for federal agencies

Peraton builds and runs secure technology for American defense, intelligence, space, and civilian agencies, from military networks to satellite ground stations. In 2025, the Federal Aviation Administration chose it to manage the overhaul of the nation's air traffic control system, replacing copper wiring with fiber and upgrading radar and radios. Its engineers, many holding security clearances, run and defend agency networks and data centers, write mission software, and operate space and communications systems, and agencies pay for this work through multiyear contracts. Peraton was formed in 2017, when private-equity firm Veritas Capital bought Harris Corporation's government IT business, and is based in Reston, Virginia.
