Job Description

We have an opening for a Guidance, Navigation & Control (GNC)/Flight Dynamics Software Developer in support of the Flight Performance Integration (FPI) program. FPI supports LLNL weapon system design and assessments with modeling and simulation utilizing custom in-house computational codes. You will perform code development work focused on a Python modeling environment (library) to generate an integrated tool to interface with multiple engineering solvers and post-processing applications. This will involve developing methods and tools to streamline the engineering workflow, facilitate automation, and provide drop-in automated data extraction. This work prepares for a planned AI driven virtual design assistant. This position is in the Computational Engineering Division (CED), within the Engineering Directorate.

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

You will

  • Contribute to and actively participate in the conception, development, implementation, execution, and documentation of new aerospace engineering analysis capabilities, such as optimal control, advanced 3DoF trajectory optimization, 6DoF trajectory optimization, and autopilot design software.
  • Support concept trade studies and assist in deriving GN&C requirements for future systems.
  • Collaborate with team members and contribute to the development of tools for managing CFD, Trajectory, Finite Element Analysis (FEA) and other numerical modeling workflows including preprocessing, post-processing, and data management, as well as providing input, recommending enhancements, and solving problems of moderate complexity using creativity with established or innovative methods.
  • Perform analysis on a variety of flight modeling related tools with an emphasis on assembling them to enable novel analysis at scale utilizing high-performance computing (HPC) resources.
  • Deliver results to, engage with, and provide support to engineering and flight modeling analysts including debugging problems, providing alternative solutions, and enabling quick feature implementation.
  • Document methods and implementation methodologies, activities, sequences, and requirements in both informal and formal reports and presentations.
  • Share relevant knowledge, analysis, and recommendations in collaboration with internal and external scientists, engineers, mathematicians, and computer scientists through reviews and working groups, including interfacing with other development teams working on tools that support analysis workflows.
