• Design and execute rigorous experiments to assess model behavior, tradeoffs, and real-world effectiveness 
• Develop techniques for model interpretability, confidence scoring, and anomaly localization 
• Define evaluation frameworks, benchmarks, and performance metrics across diverse and challenging datasets 
• Analyze failure modes, edge cases, and adversarial scenarios; develop mitigation strategies 
• Guide dataset strategy, including data curation, augmentation, and long-term sustainability 
• Collaborate with ML engineers and MLOps teams to transition research into production-ready pipelines and systems 
• Contribute to technical roadmaps, architecture decisions, and risk-reduction efforts 
• Prepare technical briefings, reports, and documentation for internal and external stakeholders 
• Mentor junior engineers and researchers; provide technical leadership across projects

Requirements

• U.S. Citizenship (required) 
• Active Top Secret Clearance (SCI eligibility; CI Poly preferred or ability to obtain)  
• Bachelor’s degree in Computer Science, Engineering, Data Science, Applied Mathematics, or related field 
• 4 years of experience in one or more areas:

  • Computer vision or image analysis 
  • Anomaly detection or forensic analytics 
  • AI/ML development in production or mission environments 
• Strong proficiency in Python and ML frameworks (PyTorch, TensorFlow, or equivalent) 
• Deep understanding of ML fundamentals: training, generalization, overfitting, optimization, and evaluation 
• Experience designing experiments and analyzing quantitative results 
• Ability to work with real-world, noisy, and complex datasets 
• Strong problem-solving and independent research capabilities 
• Excellent communication skills for both technical and non-technical audiences 

Preferred Qualifications

• Master’s degree or higher in a related field 
• Experience with: 
  • Media forensics, deepfake detection, or multimodal AI 
  • Transformer architectures, generative models, or representation learning 
  • Explainable AI, saliency mapping, or attribution techniques 
• Experience designing benchmarks and managing dataset lifecycle/provenance 
• Background supporting defense, intelligence, or high-assurance systems 
• Record of publications, patents, or internal R&D innovation
