Job Description

We have an opening for a Scientific Computing Analyst supporting the Flight Test Group. You will adapt and contribute in areas outside of your core competencies, be well-rounded, and possess a desire to expand your skillset.

You will create and maintain state-of-the-art computational mechanics algorithms, ensure the fidelity and performance of their implementation, and support their usage by multiple team members on flight scoring performance and warhead assessments. This position is in the Defense Technologies Engineering Division (DTED), within the Engineering Directorate. DTED provides support to Weapons and Complex Integration (WCI) Programs.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level. 

In this role you will 

  • Support, maintain, and expand a wide range of codes used by the flight test group, including:

    -          Control software for autonomous vehicles

    -          Analysis code for radar systems

    -          Spatial rendering software for pre-mission simulation

    -          Post-mission image analysis, including calculation of quantities of interest

  • Implement a robust system of uncertainty quantification for complex analysis codes.
  • Adapt software development and quality assurance practices and contribute to their continuous improvement.
  • Act as a code user to support mission preparedness, execution, and analysis. Contribute to technical presentations to sponsors on analysis results.
  • Innovate on new methodologies, diagnostics, or algorithms. Work with other team members to identify and proactively adapt to future software needs.
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.3 level

  • Interface with sponsors to articulate software capabilities, results, and needs.
  • Mentor other analysts, train newly hired staff and junior members.
  • Participate and drive experiments that help validate uncertainties in the code and provide briefings to sponsors on ramifications of these uncertainties.
  • Develop new software to link LIDSS analysis codes to LLNL’s internal flight modeling suite and serve as the software quality assurance point of contact for the entire LIDSS software suite.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • Master’s degree in Engineering or equivalent combination of education and related experience.
  • Comprehensive knowledge of scientific computing/numerical analysis.
  • Experience with mechanical systems (e.g., robotics, design of a physical system, rocketry).
  • Ability to interact with and contribute to code bases in Java, MATLAB, Python, and C/C++.
  • Prior experience with working in a laboratory, machine shop, or field environment.
  • Adaptable, detail oriented, and comfortable working on a cross-disciplinary team; willingness to learn and perform new duties in a fast-paced environment.
  • Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information.

Additional qualifications at the SES.3 level

  • Experience in developing new codes and vetting those codes against test data.
  • Fundamental understanding of optics principles.
  • Ability to work independently on large, complex projects with little direction and experience working with a team and directing efforts of others.
  • Experience in developing Graphical Users Interfaces (GUI) to make use of analysis tools easy for casual users of the code.

Qualifications We Desire

  • PhD in Engineering or related field.
  • Familiarity with image analysis and extracting engineering parameters from optical images.
  • Experience with development of software GUI’s for use in developing easy to use tools to aid analysis.
  • Budgeting experience.
