Weapon System Systems Engineer
Johns Hopkins Applied Physics Lab in Laurel, Maryland
Date Posted 10/20/2020
Employment Type Fulltime
Application Deadline Open until filled

Do you love to learn about and analyze complex systems?

Are you passionate about applying your analytical and technical skills to challenging questions in strategic deterrence and national defense?

Do you enjoy exploring real-world data from tactically representative weapons


If so, we're looking for someone like you to join our team at APL. We are seeking a Weapon System Systems Engineer to help us evaluate the system-level accuracy of the nation’s most complex and significant strategic deterrent--the Trident Submarine-Launched Ballistic Missile (SLBM). In addition, we need someone to advance our understanding of accuracy for the Air Force's Ground Based Strategic Deterrent replacement of the Minuteman ICBM. We are also seeking assistance with lethality analysis of proposed warheads for the Conventional Prompt Strike hypersonic weapon.

As an analyst in the System Modeling & Estimation group...

  • Your primary responsibility will be to evaluate using modeling and estimation techniques the accuracy performance of submarine launched and intercontinental ballistic missiles and the warhead lethality of hypersonic weapons.
  • You will evaluate actual representative test flight data and assess performance characteristics within unique functional domains, such as demonstrated accuracy, submarine navigation, missile guidance, warhead deployment and reentry, and fuzing.
  • You will gain subject matter expertise and contribute to a deep understanding of current weapon systems and future variants.
  • You will conduct system engineering investigations and special studies of accuracy concerns.
  • You will innovate and implement statistical estimation and physics-based analysis methodologies as needed.

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

  • Possess a PhD in applied math, statistics, physics, systems engineering, or related discipline.
  • Are skilled in statistical estimation, quantitative evaluation, and/or physics-based modeling.
  • Are skilled in scientific programming using a high-level language, such as C++, MATLAB, or Python• Possess good written and oral communication skills.
  • Collaborate effectively with all levels of staff, external collaborators and sponsors.
  • Are willing and able to occasionally travel to meetings and sponsor sites.
  • Are able to obtain an interim Secret level security clearance by your start date and can ultimately obtain a final Top Secret level clearance. Applicants selected will be subject to a Government security investigation and must meet the eligibility requirements for an SSBI and access to classified information. Preference for current SSBI. Eligibility requirements include US citizenship.

You'll go above and beyond our minimum requirements if you have experience in any of the following...

  • Maximum likelihood estimation using Fisher information
  • Kalman filtering
  • Strategic weapon system accuracy analysis (SLBM, ICBM)
  • Aided inertial navigation error analysis
  • Have a current active Top Secret level clearance
