• Strong proficiency with FreeFlyer®, STK and/or Copernicus, MATLAB®, and Python
• Strong proficiency in C++ and experience with NASA code POST2.
• Experience with the non-GPS enabled GN&C systems and sensor and navigation methodologies.
• Familiarity with NASA organizations, processes, and procedures including NASA System Engineering Standards such as the NASA System Engineering Handbook (NASA/SP-6105), NASA Procedural Requirements (NPR 7123), and NASA Space Flight Program and Project Management Handbook (NPR 7120).
• Experience working with NASA launch services providers.
• Experience with NASA deep space mission systems engineering including coordinating system requirements verification and validation between multiple organizations and centers.
• Experience with human rated space flight.

Responsibilities:

The successful candidate will support the following tasks and activities:

The Guidance, Navigation, and Control (GN&C) Engineer provides support on behalf of our customers to determine, negotiate and implement mission-enabling GN&C requirements for the GLS systems and associated hardware. Additionally, this position will perform independent modeling and simulation tool development and analysis to support independent verification and validation (IV&V) of requirements and work closely with the mission design team.

As a GN&C Engineer you will:

• Review system architecture, hardware requirements, designs, assembly procedures, test plans, procedures, and data in support of the Deep Space Logistic GN&C and occasionally Mission Design to ensure approaches are sound, component selection is appropriate for the intended usage, and suitable for the proposed application. 
• Provide recommendations for improvements to system architectures, hardware requirements, designs, test plans, and procedures if disparities/deficiencies are identified.
• Ensure NASA requirements are satisfied by design solutions and support production/control board meetings, design, and system reviews.
• Track GN&C specific requirements verification and validation progress.
• Perform computer-based analysis in support of GN&C applications for independent verification and validation (IV&V) of requirements, according to modeling and simulation best practices and following NASA standards. Including, but not limited to:

• Trajectory and attitude of the spacecraft

• 6-DOF motion simulations using in-house and NASA tools

• RPOD analysis to determine feasibility of mission operations concepts

• Navigation analysis without GPS for deep space spacecraft rendezvous

• Provide engineering insight in support of the DSL Logistic Modules providers for their GN&C system designs in relation to Avionics, Mission Design, Flight Software, and other systems.
• Evaluate various options, utilizing matrix organization support as necessary, to offer best technical guidance about various trade-offs (technical, schedule, risk, etc.)
• Work in a team environment and report to senior NASA personnel to provide status on providers development progress and issues.
• Travel as required in support of technical reviews and exchanges. 
• Select and apply engineering techniques and procedures to analyze and evaluate specific problems, data, or other features of the work which are broad in scope and complexity.
• Provide recommendations for program acceptance of requirements verification, testing, risks and hazards. 
• Perform other duties as required.
