Job Description

We have an opening for a qualified Systems Analyst to join our multidisciplinary team of applied modeling and simulation professionals. Working closely with operations researchers, weapon scientists, intelligence analysts, code developers, and other subject matter experts, you will support varied national security mission areas. As an experienced professional, you will use tools such as the Advanced Framework for Simulation, Integration and Modeling (AFSIM) software to assess how military technologies and systems perform for varied missions and in varied operational environments. As part of this effort, you will apply a combination of technical depth and breadth, critical thinking, and design principles to test, refine, and postulate potential alternatives to achieve desired mission outcomes.

Within the Computational Engineering Division (CED) of the Engineering Directorate, this position will support LLNL programs in the Strategic Deterrence and Global Security Principal Associate Directorates.

This position will be filled at either level based on knowledge and related experience as assessed by the responsibilities outlined below.

In this role, you will

  • Collaborate with scientists and researchers in a multidisciplinary team environment on the application of key technologies to military operations.
  • Leverage AFSIM and related modeling and simulation tools to analyze the application of key technologies to identified missions, identify and evaluate potential courses of action, determine their operational utility, and/or suggest possible alternatives.
  • Contribute to and actively participate in the conception, design, and execution of original research addressing program and sponsor requirements.
  • Provide input on, and recommend enhancements to, modeling and simulation technologies, approaches, applications, and/or utility for specified projects and sponsors.
  • Modify, extend, adapt, or enhance existing combat simulation tools, such as AFSIM or the Joint Conflict and Tactical Simulation (JCATS) programs.
  • Communicate with, deliver results to, and otherwise engage with project managers and external sponsors as appropriate.
  • Balance multiple projects/tasks and priorities of customers and partners to ensure deadlines are met, while working independently with limited direction within the scope of the assignment.
  • Travel as required to coordinate research with collaborators and visit sponsor, partner, and end-user sites.
  • Perform other duties as assigned.

Additional job responsibilities at the SES.3 level

  • Collaborate with project partners, developers and mid-level management, often representing the organization as the primary technical contact, sharing relevant knowledge, opinions, and recommendations to fulfill deliverables as a team.
  • Solve abstract and complex problems as required, drawing on both routine and innovative techniques and approaches to ensure project success.


  • Ability to secure and maintain a U.S. DOE Q/SCI-level security clearance which requires U.S. citizenship.
  • Bachelor’s degree in computer science, computer engineering, mathematics, operations research, or a related field, and/or experience in modeling military planning and operations, or the equivalent combination of education and related experience.
  • Proficiency with developing and using conflict simulation tools to provide analytic insight.
  • Comprehensive experience in modifying, extending, adapting, or enhancing existing combat simulation tools, such as AFSIM or JCATS.
  • Ability to effectively manage concurrent technical tasks with conflicting priorities, to approach difficult problems with enthusiasm and creativity, and to change focus when necessary while working independently under limited direction.
  • Experience working with a multidisciplinary team of scientists, engineers, and project managers to develop and apply these capabilities to inform engineering decisions.
  • Proficient verbal and written communication skills to collaborate effectively in a team environment and present and explain technical information to a variety of audiences.
  • Ability to travel.

Additional qualifications at the SES.3 level

  • Significant experience with programming using languages such as python, C++, or UNIX shell script. Expertise in modifying, extending, adapting, or enhancing existing combat simulation tools, such as AFSIM or JCATS.
  • Expertise in successfully leading diverse, highly technical teams to execute loosely defined projects with significant experience in successfully engaging external stakeholders.
  • Ability to independently develop and execute analyses, engage in any needed post-production data processing, prepare and finalize tailored reports.

Qualifications We Desire

  • Master’s degree in computer science, computer engineering, mathematics, operations research, or a related field, and/or a background in aerodynamics, radar systems, kill chain modeling, machine learning or optimization algorithms.
  • Relevant experience working with the military operational community, substantive claims to military domain knowledge, or equivalent claim to subject matter expertise with respect to the national defense enterprise.
