Description

Do you enjoy exploring and analyzing data to find data-driven solution to complex problems?

Do you want to contribute to work that is crucial to maintaining our national security and strength?

Are you continuously searching for new ways to grow your knowledge and improve your skills?

If you are graduating with a PhD in Statistics, Physics, Mathematics, Computer Science, or a related field, we would love to have you join our team! We are seeking a new PhD graduate with expertise in statistics to support multi-disciplinary teams performing a variety of quantitative tasks for defense and national security applications. You will be joining a varied team of engineers, software developers, statisticians, data scientists, and analysts who are committed to advancing the state-of-the-art in performance evaluation of the nation's strategic weapons systems throughout their lifecycle. We believe in continually growing our capabilities and cultivating a work environment that embraces innovation, integrity, trust, and teamwork.

As a member of our team, you will...

• Work with multi-disciplinary teams to support development of data collection, processing, and analysis efforts to assess the performance of a number of systems supporting the Navy and Air Force.
• Develop and evaluate statistical models for complex defense applications, including uncertainty quantification, inference, forecasting, and decision support.
• Apply statistical reasoning for data-driven studies, selecting appropriate methods (e.g., Bayesian or frequentist approaches) based on the problem.
• Quantify and communicate uncertainty, assumptions, and limitations to support sound decision‑making in complex, real‑world setting.
• Use internal funding opportunities to shape the direction of future research.
• Communicate technical knowledge by articulating ideas clearly through papers and presentations to technical staff, management, and government decision makers.

You meet our minimum qualifications for the job if you...

• Have a PhD in Data Science, Statistics, Physics, Mathematics, Computer Science or a related field.
