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.

  • Leverage AWS, MS cloud services, and AI platforms to develop, deploy, monitor, and troubleshoot applications.
  • Apply prompt engineering, tool calling, retrieval-augmented generation (RAG), and other GenAI techniques to enhance application capabilities.
  • Collaborate with developers, analysts, and subject-matter experts to refine requirements and assess feasibility; conduct code reviews, maintain documentation, and follow coding, testing, security, configuration management, and release standards. Qualifications: Required:
  • Minimum of two (2) years of relevant web development or software development experience that matches or relates to the technologies outlined below.
  • Active TS/SCI clearance with CI Polygraph.
  • Demonstrated experience developing and supporting web applications using HTML, JavaScript, CSS, C#/.NET, and Bootstrap.
  • Experience developing or integrating GenAI applications, LLM-powered interfaces, AI assistants, or other AI-enabled solutions.
  • Knowledge of AI terminology and integration approaches
  • Experience integrating multiple LLMs or AI services through APIs, SDKs, or other application integration mechanisms.
  • Experience with AI platforms such as Microsoft Foundry, Amazon Bedrock, Amazon SageMaker, or comparable services.
  • Experience developing web APIs, backend services, and SQL-based solutions.
  • Experience using AWS and/or Microsoft cloud services to develop, deploy, monitor, and support cloud-based applications.
  • Familiarity with MCP servers, tools, and integrations that connect AI capabilities to external systems.
  • Practical knowledge of prompt engineering, tool calling, retrieval-augmented generation (RAG), or similar techniques for building LLM-powered applications.
  • Ability to evaluate technical tradeoffs, troubleshoot complex issues, and develop secure, reliable, and maintainable software. Desired:
  • Bachelor's degree in Computer Science, Information Systems, Software Engineering, or a related field, or equivalent work experience.
  • Experience developing software with Python.
  • Experience with containerized or serverless architectures and cloud services such as AWS Lambda, ECS, RDS, or CloudWatch.
