The Leidos Chief Data & Analytics Office (CDAO) is a high-growth organization at the center of the company's technology strategy. Our Operational AI (Ops.AI) division is seeking a motivated and talented Senior Artificial Intelligence & Machine Learning (AI/ML) Engineer to join our team. This role is critical for transforming innovative models into the robust, production-ready solutions that power our mission-critical applications.

This is an exciting opportunity for a hands-on engineer who excels at bridging the gap between data science and software engineering. You will be responsible for the entire lifecycle of our AI/ML models, from design and training to deployment, optimization, and monitoring. You will work with a team of experts to build the scalable, high-performance, and trusted AI systems that help Leidos accelerate innovation and improve mission outcomes.

Primary Responsibilities

• Design, train, and deploy a wide range of AI/ML models for mission-critical applications, ensuring they meet performance and scalability requirements.
• Implement and manage automated MLOps pipelines for model monitoring, retraining, and lifecycle management to ensure continuous delivery and reliability.
• Optimize model performance, scalability, and resource consumption in production cloud and on-premise environments.
• Collaborate with data scientists, software engineers, and systems architects to translate model prototypes into hardened, production-grade solutions.
• Uphold software engineering best practices, including robust version control, comprehensive testing, and CI/CD processes.
• Stay current with industry trends and best practices in MLOps and operational AI to continuously improve the team's capabilities.

Basic Qualifications

• A Bachelor's degree in Computer Science, Engineering, or a related quantitative field with 8+ years of professional experience, or a Master's degree with 6+ years of relevant experience.
• Demonstrated programming proficiency in Python and hands-on experience with major ML libraries and frameworks (e.g., TensorFlow, PyTorch, Scikit-learn).
• Experience with software engineering best practices and tools, including version control, automated testing, and CI/CD pipelines.
• Solid understanding of the full machine learning lifecycle, from data preparation and model training to deployment and monitoring.
• Must be a U.S. Citizen and have the ability to obtain and maintain a U.S. security clearance.

Preferred Qualifications

• Experience with MLOps platforms such as MLflow, Kubeflow, or AWS Sagemaker.
• Experience with containerization and orchestration technologies (e.g., Docker, Kubernetes).
• Familiarity with Infrastructure-as-Code (IaC) tools like Terraform or CloudFormation.
• Experience with large-scale data processing tools (e.g., Apache Spark).
• Hands-on experience with a major cloud platform (AWS, Azure, or GCP).
• Knowledge of AI ethics, responsible AI practices, and federal compliance standards (e.g., NIST, CMMC).
• Contributions to open-source ML projects.

At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.”

If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
