This position supports the effort to modernize the ground-based leg of the United States’ nuclear triad, the Sentinel Weapon System (WS), using CBM+, which is the Department of Defense’s (DoD) preferred method of maintenance and sustainment for large-scale weapon systems. CBM+ works to optimize scheduled maintenance, thereby reducing Lifecycle Cost (LCC).

Responsibilities

• Develop data architectures in support of predictive modeling for a large-scale WS designed to be operational for multiple generations.
• Create statistical, ML, and physics-based predictive models that forecast the Remaining Useful Life (RUL) of Line Replaceable Units (LRU) identified in CBM+ trade studies. This includes processes like data exploration, model feasibility/accuracy evaluation, cost evaluation, model development & validation, and model demonstration.
• Establish templates and standards for modeling and tracking CBM+ items and processes.
• Support development of the CBM+ Program Plan.
• Collaborate with both NG and customer data scientists to define a data architecture for the WS; ensure the CBM+ tech stack remains aligned with wider architecture tools and plans.
• Engage directly with the customer in support of evolving program requirements.

• Hands-on experience with predictive maintenance, Prognostics and Health Management (PHM), or RCM methodologies.
• Strong foundations in statistics, including survival/reliability analysis, time-series modeling, regression, and uncertainty quantification.
• Strong foundation in data engineering and analysis, including structured (relational, time-series) and unstructured (logs, text, imagery) data types, data pipeline design, and hands-on experience managing real-world data quality challenges such as missingness, sensor drift, and irregular sampling.
• Production experience with relevant Amazon Web Services (AWS) services (e.g., S3, Glue, SageMaker, Redshift, etc.), Palantir Foundry, Databricks, and/or Snowflake.
• Proven expertise in artificial intelligence, demonstrated by hands-on experience designing, building, and deploying machine learning models and AI solutions in production environments.
