The key purpose of the position is to plan and perform systems engineering activities associated with the development, integration and verification/validation of SLS Integration and Test Facilities (IATF) and Software Development Facilities (SDFs) that will be used to verify the integrated avionics system for the Space Launch System (SLS) at NASA’s Marshall Space Flight Center.

This position will also perform system engineering activities associated with the development and verification of SLS Emulators that will be delivered and integrated into facilities used to develop/test the NASA Multi-Purpose Crew Vehicle (MPCV), the Second Stage Rocket, Interim Cryogenic Propulsion Stage (ICPS), or Centaur V (CV), and the Launch Control System.

Responsibilities:

• Provide systems engineering support to the NASA SLS Avionics and Ground Systems Test Branch (ES53) at MSFC in support of the Space Launch System (SLS) program.

• Apply systems engineering methods to define/evaluate SLS IATF, SDF and Emulator requirements, interfaces and plan/support IATF, SDF and emulator verification/validation activities.

Additional responsibilities are defined below:

• Perform or coordinate systems engineering activities including Trade Studies and Analysis, Requirements Definition and Traceability, Requirements Allocation and Verification, Interface Definition, System Integration and test, and Design Verification and Validation. Also ensure requirements and specifications can be verified and validated, including risk mitigations, usability and NASA requirements.

• Work closely with SLS IATF software, hardware, and facility development personnel during development, understanding of configurations in development, operation, verification, and validation of IATF systems and emulators.

• Assist the project verification and validation team by defining and delivering verification and validation project deliverables.

• Identify the data that will be required to show objectively that all configurations of the product meet their requirements, as well as customer needs.

• Ensure that all test systems and equipment are appropriately validated and controlled.

• Review and analyze IATF system test data and record pass/fail results and conclusions. Ensure that results are traced to requirements.

• Measure and report on progress toward completion of verification and validation, and summarize the verification and validation performed, the data reviewed, and conclusions reached in compliance.

• Support completion of development testing, to characterize designs and understand trade-offs.

• Create or contribute to project deliverables which may include verification and/or validation plans, protocols, and reports; execution of the plans and protocols; and resolving deviations.
