Position Description

As a Navigation Engineer, you will help develop and verify the INS/GPS navigation system for the Block-1B configuration of NASA's Space Launch System (SLS). You will need to develop a detailed understanding of the navigation sensors in both nominal and off-nominal conditions and their interactions and interfaces to flight computers and software. You will use that understanding to help create software models that integrate with existing 6-DOF simulations and navigation software.

As a Navigation Engineer, you will also develop test scenarios that will ensure models behave and interact with system avionics as expected. You will assess and analyze test data to characterize systems and to identify and isolate unexpected results and discrepancies between models and observed behaviors.

As part of the SLS Navigation team, you will provide peer review and collaborate with other members of the team.

As a Senior Engineer, you will be expected to:

  • Have extensive knowledge and expertise in your own discipline and broad knowledge of related disciplines,
  • Recommend best practices to solve complex problems and to improve products and services,
  • Work independently and provide guidance to other engineers.




A degree in Aerospace Engineering, Mechanical Engineering, or a related field is required. A degree from an ABET accredited institution preferred. Typically, educational requirements are the equivalent of a PhD with at least 4 years of experience, an MS with at least 8 years of experience, or a BS with at least 10 years of experience.


Skills and experience should include:

  • Experience with inertial navigation and GPS-aided navigation systems, preferably for aerospace applications
  • Ability to develop test plans, cases, and scenarios to verify the integration of navigation systems from a software and algorithmic perspective.
  • Demonstrated ability to use test data to characterize system performance and identify anomalous behaviors.
  • Strong proficiency in programming, especially with Python or C/C++. Experience with MATLAB and Simulink is highly desired.
  • Knowledge of astrodynamics and flight mechanics
  • Knowledge of Monte Carlo, design of experiments, and statistical analysis
  • Proficiency with modeling and simulation of aerospace vehicles
  • Strong proficiency in technical writing, communication, and presentation.
