Job description

The Senior Software Engineer II position in AI/Autonomy systems development will emphasize modeling/simulation (M+S) and software testing of complex autonomy systems in operationally realistic scenarios. The successful applicant will be responsible for developing and supporting advanced M+S infrastructure for testing and evaluation of AI/Autonomy-enabled systems in multiple domains.

 

 Essential Functions:

  • Develop advanced M+S infrastructure, and support testing of multi-vehicle autonomy for operational environments.
  • Provide relevant technical expertise as part of a team to design, implement, simulate, and test autonomy software systems for uncrewed, multi-vehicle autonomy systems.
  • Support presentation of technical information and data to internal and external customers.
  • This role may require occasional travel (10%) when necessary.
  • Must be able to obtain and maintain a United States Secret Security Clearance.

Requirements

Basic Qualifications:

  • Bachelor’s degree (or higher) in Engineering, Computer Science, Data Science, Math, Statistics, Robotics or related subject area and 5+ years of related experience.
  • Experience in Advanced Framework for Simulation, Integration and Modeling environment including developing new scenarios and models; C++ plugins to AFSIM; interfaces to JSE; and configuration-managed large-scale simulation test data.
  • Prior experience in model-in-the-loop (MIL), software-in-the-loop (SIL), digital twin and/or LVC testing of advanced AI/autonomy software technologies.
  • Experience with C/C++, Python, and relevant high-performance compute (HPC) infrastructure used for large-scale, distributed simulation (DIS) environments.
  • Experience working with software technologies for Robotics, Machine Learning, and/or Multi-agent AI/Autonomy Systems.
