Position Description
The Amentum Space Exploration Division (ASED) Guidance, Navigation, and Control (GN&C) team is a high performing group executing challenging tasks to design and integrate GN&C systems for projects ranging from CubeSats to NASA’s Space Launch System (SLS). 
We are searching for highly qualified candidates to support the design, development, and oversight of Golden Dome work in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center as a Senior Controls, Modeling, Simulation, and Analysis Engineer. This exciting work will assist external partners with the Design, Development, Testing, and Engineering (DDT&E) of the “Golden Dome for America” assets including satellite constellations, space-based interceptors, and directed energy platforms. 
Responsibilities include but are not limited to:
•    Review and analyze the mission design and/or the Attitude Determination and Control System (ADCS) design of Golden Dome providers, perform independent verification and/or validation of contractor results where necessary, and identify risks in the providers’ proposed concepts and designs.
•    Review and co-develop Concepts of Operations (ConOps) for in-space technology demonstration satellite bus contractors and proposed missions, including operational modes, mission phases, state transitions, nominal and contingency operations, and command and control architecture.
•    Review, analyze, and simulate (in Systems Tool Kit (STK) or equivalent) in-space deployer platform trajectories, including orbital mechanics validation, orbital variation analysis of deployed assets, and evaluation of deployment sequencing and phasing strategies.
•    Review, analyze, and independently simulate in-space deployer pointing stability performance and detumble requirements for deployed assets, including analysis of angular rates, momentum management, disturbance torques, separation dynamics, and time-to-stabilization for deployed payloads.
•    Review, analyze, and independently simulate pointing accuracy and stability of multiple assets within the Golden Dome architecture, including jitter analysis, slew rate performance, target tracking capabilities, line-of-sight stability, attitude knowledge and control error budgets, and inter-satellite relative attitude coordination.
•    Review and assist with technology maturation efforts through the Technology Readiness Level (TRL) scale for ultimate incorporation into Golden Dome assets, including assessment of development progress, identification of technical gaps, evaluation of test and validation approaches, and recommendations for advancement criteria.
•    Attend offsite Technical Interchange Meetings (TIMs) with providers and subcontractors to review technical progress, assess design maturity, provide independent technical evaluation, and identify integration risks and mitigation strategies.
•    Attend regular status meetings with NASA management and critical stakeholders to provide technical briefings, communicate risk assessments, report on provider performance, and coordinate inter-agency technical activities.
