About the Job

Requirements

  • Active Top Secret Sensitive Compartmented Information clearance with polygraph is required.
  • A Bachelor of Science in Computer Science, Cybersecurity, Information Systems, or a related field and 10+ years of relevant experience are required; additional experience may substitute for the degree, and vice versa.
  • Familiarity with machine learning concepts, including model training, evaluation, tuning, and performance measurement.
  • Ability to assess model effectiveness using quantitative metrics and communicate tradeoffs.
  • Depth of experience with prompt engineering.
  • Proficiency in Python and experience developing RESTful APIs and backend services.
  • Experience supporting AI/ML, data, cloud, or platform engineering efforts in government, defense, or enterprise environments.
  • Understanding of modern AI concepts, including large language models, embeddings, retrieval-augmented generation, vector search, and agentic workflows.
  • Familiarity with Microsoft and/or AWS platform ecosystems.
  • Proficiency using command-line interfaces such as Windows PowerShell or Command Prompt for routine development, troubleshooting, scripting, and automation tasks.
  • Working knowledge of cloud architecture, containers, APIs, data services, identity and access management, and secure system integration.
  • Ability to understand how AI applications depend on underlying platform components such as model hosting, pipelines, storage, orchestration, and monitoring.
  • Experience managing databases, including designing and maintaining relational databases, writing and optimizing SQL queries, implementing backup and recovery procedures, and applying database security and performance best practices.
  • Experience with configuration management, including defining and maintaining configuration baselines and using tools such as Ansible, Puppet, Chef, and Terraform to manage infrastructure and application settings.
  • Ability to rapidly prototype solutions, iterate based on user feedback, and operate effectively in ambiguous problem spaces.
  • Ability to translate complex technical issues into actionable guidance for mixed technical and non-technical audiences.

Responsibilities

  • Develop full-stack applications and services that use large language models, retrieval-augmented generation, agentic workflows, and other emerging AI capabilities.
  • Design, develop, and deploy AI/ML models and tools for data mining, predictive modeling, and knowledge discovery.
  • Integrate AI/ML capabilities into a secure, cloud-based data architecture and ensure interoperability with existing systems through standardized APIs.
  • Implement and monitor model performance, data and concept drift, and key metrics in real time; support model retraining and fine-tuning as new data becomes available.
  • Collaborate with data engineers, software developers, and stakeholders to define requirements, validate outputs, and support mission deliverables.
  • Ensure AI/ML workflows comply with Department of War cybersecurity, data privacy, and access-control requirements, including operation in isolated cloud environments.
  • Support knowledge transfer and training activities, including developing tutorials and best practices for AI/ML usage.
  • Educate stakeholders on AI platform concepts, emerging patterns, and implementation best practices in government environments.
  • Assess data patterns in systems and network misconfiguration.
  • Work with cyber analysts to support quick-turn requests for vulnerability information by continually improving large language models.
  • Conduct analyses of alternatives to compare internally developed approaches with commercial, open-source, and industry-standard techniques.
  • Develop and execute experiments to assess model performance using appropriate evaluation metrics and representative datasets.
