You will support Systems Engineering & Integration (SE&I) activities in a multidisciplinary and collaborative environment. The Systems Integration Engineer will interface and collaborate with SE&I team members, contractors, government civilians and members of the USSF. The Systems Integration Engineer will lead and support several working groups responsible for leading technical discussion, resolve and identify risks, requirement gaps, developing briefings, writing and tracking action items, and authoring meeting minutes.

• Work with Government and contractor personnel to close gaps with customer requirements across the program; support major requirements reviews, design reviews, and other associated meetings
• Lead and support Government/Contractor Working Group meetings—by developing briefings, leading discussion, and writing minutes—to address/resolve risks, issues, and action items
• Review proposed changes to the technical baseline for impacts to enterprise capabilities and to cross-stakeholder integration concerns
• Define and deliver alternative solutions to address different integration challenges; manage schedule impact and overall delivery of products
• Facilitate review of contractor-developed program documents by performing technical assessments and providing comments, compiling other review team comments, and working with contractors to adjudicate the comments.
• Serve as a subject matter expert to assess technical issues and to prepare briefings to U.S. Space Force program office personnel and other stakeholders; provide courses of actions to support Government decisions
• Support management of risks, issues, interdependencies, identifying schedule disconnects and conflicts, developing action plans for resolution, and assisting the Government in executing selected solutions
