Job Brief
Python, AI/ML frameworks
Job Description
RealmOne was built on the principle that people matter first and foremost. We believe in providing a strong work/life balance by investing in our employees and encouraging professional and personal growth. We do this by offering exceptional benefits, flexible schedules, and the tools necessary to achieve success through paid training, mentoring, and the opportunity to work alongside top-notch industry professionals.
Join us on this journey as we execute this mission-critical contract providing high-end analytics and data science services within the REALM of cybersecurity.
Your effort and expertise are crucial to the success and execution of this impactful mission. This opportunity supports a team of Data Scientists, Cryptologic Computer Scientists, Cryptanalytic Computer Scientists, Cryptologic Cyber Planners, Intrusion Analysts, Protocol Analysts, Signals Analysts and Reverse Engineers, responsible for improving, protecting, and defending our Nation's Security.
Job Description:
  • The DA2s serve as behavioral scientists for AI systems, defining what constitutes "normal" behavior before identifying anomalies. In Phase 1, they conduct controlled experiments across various AI models, including commercial services and open-source models deployed locally, to observe resource utilization, API interaction patterns, and output features. They analyze telemetry data from these systems to establish statistical baselines and create anomaly detection algorithms that can differentiate between typical operational variations and security issues. A key aspect of their work involves distinguishing between conversational AI that functions in discrete sessions and autonomous AI agents that maintain persistent states and can alter their workflows.

The Level 2 Data Analyst shall possess the following capabilities:
  • Python data analysis (pandas, scikit-learn, numpy).
  • Statistical analysis and anomaly detection.
  • Data visualization skills.
  • Understanding of APIs and how systems communicate.
  • Ability to document and explain results to senior leadership.
  • Experience with AI/ML frameworks (TensorFlow, PyTorch, Hugging Face).
  • Understanding of how AI systems behave (conversational vs. autonomous agents).
  • Cybersecurity or threat detection background.
  • Security clearance or clearance eligible.
  • Will analyze behaviors of commercial AI services (ChatGPT, Claude) and open-source models.
  • Will build detection algorithms (context) for AI-specific anomalies.
  • Will work with large telemetry datasets.
  • Will establish what "normal" AI behavior looks like for the Government's environment.

Qualifications:
  • Six (6) years of demonstrated experience as a data analyst in programs and contracts of similar scope, type, and complexity is required.
  • Three (3) years of demonstrated experience in cybersecurity activities in programs and contracts of similar scope, type, and complexity is required.

Certifications Required:
  • Requires DoD 8570 compliance Information Assurance Technical (IAT) Level I or Level II certification, and Computing Environment (CE) certification. The CE certification requirements can be fulfilled with either Microsoft OS, Cent OS/Red Hat OS CE certifications.
  • Requires successful completion of the Splunk software training course "Fundamentals 1".

Position requires active Security Clearance with appropriate Polygraph
