Responsibilities

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
