Do:

Support Landsat Next ConOps development, including simulator usage and mission-level integration/testing considerations, and develop the mission simulator requirements and ConOps documents. Define simulator needs (mission objectives, measurement concept, instrument concept), mission design, and interface engineering/management requirements, including late-lifecycle considerations for pre-launch, launch, and commissioning verification. Track and oversee simulator engineering inputs for pre-formulation/formulation studies across spacecraft, payload, ground, and launch services. Serve as Project liaison to USGS on all simulator matters, and lead a weekly Simulator Working Group with key stakeholders to resolve issues and align on simulator needs. Interact with USGS engineering/operations teams to ensure simulator requirements, design, and I&T meet end-user testing and operational needs. Review mission systems/operations documentation and prepare requirements/specification packages conforming to Task Order standards, including interface identification and ICD development support. Provide M&ISE support (system design assessment for Design Reviews, requirements/specification review, interface management strategy) and technical inputs for simulator design/problem-solving. Analyze contractor progress reports with recommendations to the project, and participate in Observatory/Spacecraft/Launch Vehicle/Instrument systems reviews, meetings, and working groups.

What You'll Need:

Required & Desired Skills BS or MS in Aerospace Engineering or related field with a minimum of 5 years of relevant experience Previous experience with and understanding of hardware simulators (not software simulation) is required.
