nou Systems, Inc. (nSI) is a 100% employee-owned company!
We value teamwork and collaboration, and this transition allows us to take that commitment to a new level. nSI empowers our customers by supplying products, services, and expertise
with powerful, data driven insights that transform defense systems and improve capabilities.

We are pleased to announce the opening for an AI Engineer who will join our Technical Solutions division and become part of our rapidly growing technology company operating in missile defense, cybersecurity, test range modernization, biotechnology, and space control market spaces. You will be part of a team designing machine learning solutions from the lab to the field.

You’ll develop, train, and analyze machine learning models for supervised learning and reinforcement learning. You’ll work on a mix of projects, some of which will include other data scientists, others of which will require you to help educate non-data-science teams on the value and limitations of machine learning solutions. You will:

• Help identify and design training data sets.
• Implement and customize ML models from open literature.
• Visualize and communicate your results in written documents and oral presentations.
• You’ll support multiple teams and must be able to work effectively with other teammates.

• Bachelor’s degree in a STEM field.
• Academic, internship, or professional experience with AI development (RL, XAI, LLM)
• 1-3 years of hands-on experience with deep learning models (supervised, unsupervised, and reinforcement learning) using PyTorch, Tensorflow, or Jax.
• You must possess or can obtain an active Secret clearance.

This is a junior level position. We are looking for hands-on experience with deep learning models as well as software development fundamentals in Python. We are looking for great written and verbal communication skills.

• Strong intellectual curiosity. Our solutions often require creative implementations and combinations of state-of-the-art methodology .
• Comfort with self-direction. You'll work with our top technical talent, but we're looking for evidence you can diagnose a problem and approach it independently.
• Experience with time series data, satellite imagery, and graph neural networks.
• Experience with RL development using OpenAI Gymnasium and Ray RLlib.
• Experience with RL algorithms, including Q-Learning and Actor-Critic methods.
• Experience with MLOps tools (PyTorch Lightning, Optuna, MLflow, etc.).
• Experience with Dev Ops tools (Git, Gitlab, CI/CD, Remote Computing, Docker)
