Tech Stack
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
