About the role

  • Contribute to the design, analysis, and implementation of advanced GNC systems for spacecraft applications
  • Develop, implement, and evaluate GNC algorithms, focusing on one or more areas of guidance, navigation, control, and Fault Detection, Isolation, and Recovery (FDIR)
  • Program and optimize simulations using SIMULINK and STK
  • Model and analyze GNC sensors and actuators such as IMUs, GPS, star trackers, Reaction Control Systems (RCS), Reaction Wheels, Magnetic Torquer Bars, Control Moment Gyros, and LIDAR
  • Run and modify Monte Carlo simulations, performing in-depth analysis to identify issues and optimize system performance
  • Analyze and implement autonomous GNC mode transitions to ensure system reliability and robustness
  • Take ownership of a group of performance requirements by conducting relevant analysis to ensure compliance
  • Work with GNC flight software (FSW) in target test simulation environments to validate functionality
  • Document technical findings and communicate results to stakeholders and team members.

Requirements

  • Requires bachelor's degree in a related field (or equivalent work experience in lieu of degree)
  • Typically, 2+ years of related experience
  • Strong understanding of one programming language, and general knowledge of others
  • Strong understanding of software development principles
  • Ability to design, code, test, and debug complex software applications
  • Experience with different software development methodologies such as Agile and Kanban
  • Ability to work independently and in a team
  • The ability to obtain and maintain a U.S. Security Clearance is required.
  • Strong proficiency in SIMULINK programming and STK, with familiarity in C, C++, Python, and version control tools such as GIT/SVN
  • Fundamental knowledge of GNC algorithms and experience with designing at least one of guidance, navigation, control, or FDIR algorithms
  • Understanding of the working principles of IMUs, GPS, star trackers, RCS, non-propulsive actuators (Reaction Wheels, Magnetic Torquer Bars, Control Moment Gyros), and LIDAR
  • Strong fundamental knowledge of dynamic modeling, control, guidance, or navigation algorithm design, state-space systems, SISO, and MIMO systems
  • Ability to estimate workload independently and accurately on short-term tasks, including JIRA tickets
  • Experience running Monte Carlo simulations and performing in-depth analysis to troubleshoot and optimize GNC systems
  • Strong understanding of autonomous GNC mode transitions and ability to perform relevant analysis
  • Familiarity with SIMULINK autocoding and Linux systems for simulation and software integration
  • Ability to take ownership of performance requirements and conduct detailed analysis to ensure compliance
  • Experience working with GNC flight software in target test simulation environments and conducting validation testing
  • Knowledge of spacecraft subsystems, including power and thermal systems, communication antennas, and control structure interaction principles
  • Effective communication skills and ability to work collaboratively in a team environment.
