• Production ML systems

• Strong Python skills and experience with ML libraries (NumPy, pandas, scikit-learn, PyTorch, TensorFlow)
• Experience developing, training, and deploying ML models in real-world applications
• Solid understanding of the ML lifecycle (data ? training ? validation ? deployment ? monitoring)
• Experience building maintainable, production-quality software
• Familiarity with Docker and cloud environments (AWS, Azure, or Google Cloud Platform)
• Experience working in Agile and CI/CD environments
• Strong problem-solving, communication, and collaboration skills, * Master's degree in a related field
• Experience with computer vision, image/video analytics, or sensor data (e.g., RF, SAR)
• Experience transitioning models from research to production environments
• Familiarity with experiment tracking, model versioning, and reproducibility practices
• Experience with GPU-based ML workflows and cloud ML platforms
• Background in defense, intelligence, or other regulated environments

• Competitive compensation & benefits
• 9/80 flexible work schedule
• Professional development & tuition assistance
• Small, agile team with high ownership and visibility
• Work on mission-critical systems supporting national security
