Weapon System Analyst

Johns Hopkins Applied Physics Laboratory
Laurel, MD Intern
POSTED ON 8/2/2026
AVAILABLE BEFORE 8/30/2026
Description

Do you have a passion for physics, math, and data analysis?

Do you enjoy taking a complex physical problem and trying to represent it through mathematics and code?

Are you looking for a role where you can be mentored by world-class experts and grow into a specialist in physics-based modeling and statistical inference?

Are you interested in defining methodologies and processes that will be used for the testing and evaluation of current and future weapon systems?

If so, we’re looking for someone like you to join our team at APL!

The System Modeling, Evaluation, and Planning Group is seeking experienced analysts to support the technical evaluation of the nation’s primary strategic deterrents. You will join a multidisciplinary team of engineers, physicists, and mathematicians.

As a Weapon System Analyst you will...

  • Develop and Refine Physics Models by creating and improve high-fidelity physics-based models of complex systems, including inertial navigation (accelerometers, gyroscopes) and missile/reentry dynamics.
  • Lead the experimental design process for flight and ground tests to ensure data collection is optimized for model validation and parameter estimation.
  • Perform Statistical Validation by leveraging real-world collected data to estimate underlying physics-based errors, using statistical methods to determine how well models predict actual system behavior.
  • Apply advanced statistical techniques to “work backward” from observed data to identify the physical properties or errors that caused the observed effect.
  • Build Computational Frameworks by developing robust tools in C , MATLAB, or Python to facilitate analyses for important reports and deliverables.
  • Assess the accuracy of current strategic weapon systems and support the engineering of future systems to meet mission needs.

Qualifications

You meet our minimum requirements if you...

  • Hold a Bachelor’s degree in Physics, Applied Math, Applied Statistics, Engineering, or a closely related field.
  • Have one or more years of professional experience in data analysis or physics-based modeling
  • Have strong foundational skills in a scientific language (C , MATLAB, or Python).
  • A solid grasp of linear algebra, calculus, and basic probability/statistics.
  • A strong desire to learn complex physical systems and a willingness to dive deep into technical documentation
  • Are able to acquire an Interim Secret level security clearance by your start date and can ultimately acquire a final Top Secret level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

You'll exceed our minimum requirements with experience in any of the following...

  • Statistical analysis, parameter estimation and inverse problems, Kalman filtering, experimental design, Bayesian inference (e.g., MCMC), or Maximum Likelihood Estimation
  • Have experience working in large collaborative environments that require teams of engineers, physicists, statisticians, and applied mathematicians
  • Prior experience with tactical or strategic missile systems, or prior experience with inertial navigation systems
  • Hold an active Secret or higher-level clearance
