The engineer will take solutions from concept and prototype through deployment and sustainment, translating mission and technical requirements into scalable capabilities. The role involves collaboration with cyber operations teams, data scientists, engineers, and Government stakeholders. An active TS clearance is preferred, and the candidate must be eligible to obtain SCI access.

Requirements

At least 5 years of experience in artificial intelligence, machine learning, data science, cybersecurity analytics, or related technical disciplines.
Strong proficiency in Python and AI/ML frameworks such as PyTorch, TensorFlow, or Scikit-learn, or comparable technologies.
Applied knowledge of cybersecurity operations, threat hunting, threat intelligence, and identifying malicious or anomalous activity across enterprise environments.
Hands-on experience integrating large-scale cybersecurity datasets, including network traffic, DNS telemetry, endpoint activity, security logs, and threat intelligence.
Working knowledge of neural networks, transformers, natural language processing, unsupervised learning, and generative AI.
Ability to deploy, integrate, and sustain AI/ML capabilities within secure enterprise, cloud, or mission environments.
Bachelor's degree in Computer Science, Artificial Intelligence, Machine Learning, Data Science, Cybersecurity, Mathematics, or a related technical field.
Must be eligible to obtain SCI access; an active TS clearance is preferred.
Demonstrated ability to translate mission requirements into AI-enabled threat hunting capabilities that improve detection, investigation, and prioritization.
Strong communication and collaboration skills, including the ability to work across cyber operations teams, data scientists, engineers, and Government stakeholders.
