• Experience with Python for scientific computing and algorithm prototyping (NumPy, SciPy, scikit-Image, OpenCV, scikit-learn, PyTorch, or TensorFlow).
• Familiarity with C++ development and willingness to grow  toward production-quality implementation.
• Foundational knowledge of image processing and computer vision techniques (e.g. filtering, segmentation, feature extraction, optical flow).
• Basic understanding of deep learning methods for detection/recognition/tracking.
• Ability to analyze algorithm performance, identify limitation, and clearly communicate findings.
• Strong communication skills and ability to work with multi-disciplinary teams.
• Familiarity with version control (Git), JIRA, Agile workflows, and software engineering fundamentals.
• Candidate must be a resident of the North Alabama area or willing to relocate to the Huntsville - North Alabama, AL area.
• Candidate must be a U.S. Citizen and possess (and be able to maintain) a Final Secret Clearance or meet the eligibility to obtain (and maintain) a Final Secret Clearance.

Preferred Qualifications.

• Active SECRET clearance or above.
• Familiarity with EO/IR imaging system concepts (pixels, noise, dynamic range, contrast, spectral bands)
• Exposure to embedded systems, GPU acceleration (CUDA), or real-time processing pipelines.
• Experience working with large datasets and automated evaluation frameworks.
• Knowledge of ATA/ATR concepts, evaluation metrics, and operational considerations.
