Profile match
CACI International is an American technology company founded in 1962 that works almost entirely for United States defence, intelligence and federal civilian agencies. It has moved from being a conventional IT services contractor toward supplying its own technology, with a substantial expeditionary electronic warfare and signals intelligence product line, photonics and optical communications for space, and secure network modernisation. Headquartered in Reston, Virginia, the company employs more than twenty thousand people, the majority holding security clearances, and has grown through a steady programme of acquisitions that add differentiated technology rather than headcount alone.
Job Title: AI/ML Software DevelopmentJob Category: Information TechnologyTime Type: Full timeMinimum Clearance Required to Start: SecretEmployee Type: RegularPercentage of Travel Required: Up to 10%Type of Travel: Local* * *

CACI is seeking a skilled and experienced AI/ML Subject Matter Expert (SME) to join our dynamic team supporting a Department of Defense (DoD) customer at Aberdeen Proving Ground (APG), Maryland.

This position will work closely with Research & Development (R&D) teams to evaluate, develop, assess, and validate advanced Artificial Intelligence and Machine Learning solutions. The successful candidate will conduct Independent Verification & Validation (IV&V) activities, analyze model performance and effectiveness, and produce technical reports that objectively assess AI/ML capabilities and limitations.

This role is intended for candidates with a strong foundation in mathematics, statistics, machine learning theory, and data science. While familiarity with generative AI technologies is desirable, the primary focus is on understanding, evaluating, and improving AI/ML methodologies rather than AI operations, prompt engineering, or application-level integration alone.

The ideal candidate is intellectually curious, scientifically rigorous, and comfortable diving into internally developed, vendor-provided, and research-partner solutions to understand how they work, assess their strengths and weaknesses, and communicate findings clearly to both technical and non-technical stakeholders.

________________________________________

Responsibilities

  • Collaborate with R&D teams throughout the entire project lifecycle, from concept development and proposal evaluation through implementation, testing, and transition to operational DoD environments.
  • Evaluate AI/ML models, architectures, and products using quantitative and scientifically rigorous methodologies.
  • Conduct Independent Verification & Validation (IV&V) of AI-enabled systems and assess performance, reliability, robustness, security, explainability, and operational suitability.
  • Generate technical reports, white papers, and recommendations regarding model effectiveness, limitations, risks, and opportunities for improvement.
  • Work with industry partners through Cooperative Research and Development Agreements (CRADAs) and other collaborative efforts to provide constructive technical feedback on AI/ML products and solutions.
  • Partner with academic researchers and industry organizations to guide research efforts toward mission-relevant applications and measurable outcomes.
  • Assess emerging AI technologies, algorithms, and research developments for applicability to DoD mission requirements.
  • Analyze AI/ML systems for safety, bias, robustness, explainability, and adversarial resilience.
  • Collaborate effectively with software engineers, data scientists, researchers, government stakeholders, and external partners.
  • Participate in code reviews, architecture discussions, technical evaluations, and experimentation efforts.
  • Communicate technical findings and recommendations to leadership, engineering teams, and customers in a clear and objective manner. ________________________________________ Required Qualifications
  • U.S. Citizen with an active Secret security clearance.
  • One of the following education and experience combinations: o Bachelor's degree in Artificial Intelligence, Computer Science, Data Science, Mathematics, Statistics, Applied Mathematics, Operations Research, Computer Engineering, Physics, or a related quantitative discipline and 8+ years of relevant experience; OR o Master's degree in Artificial Intelligence, Machine Learning, Data Science, Statistics, Applied Mathematics, Computer Science, or a related quantitative field and 6+ years of relevant experience; OR o PhD in Artificial Intelligence, Machine Learning, Data Science, Statistics, Applications
