The Senior Proposal Writer leads the development of proposal sections, contributes to win strategies and messaging, ensures compliance with solicitation requirements, and produces high-quality proposal documents under demanding deadlines. The position requires exceptional writing, editing, interviewing, and organizational skills, along with a strong understanding of the federal acquisition process and defense industry terminology.

  • Write and edit technical, management, executive summary, past performance, staffing, quality, manufacturing, and transition plan sections. 
  • Ensure proposal content is compliant with solicitation instructions, page limitations, formatting requirements, and evaluation criteria. 
  • Develop proposal outlines, storyboards, content plans, and annotated templates. 
  • Produce or acquire illustrations, diagrams, and other visual aids to enhance the understanding of complex aerospace systems and workflows. 
  • Participate in proposal reviews, including Pink Team, Red Team, Gold Team, and White Glove reviews. 
  • Incorporate reviewer comments and manage document revisions throughout the proposal lifecycle. 
  • Maintain proposal libraries, reusable content, resumes, past performance narratives, and corporate capability statements. 
  • Maintain confidentiality of proprietary, Controlled Unclassified Information (CUI), export-controlled, and competition-sensitive information. 
  • Continuously improve proposal creation and management processes to meet evolving team needs, aerospace industry requirements, and customer expectations. 

REQUIRED QUALIFICATIONS  

  • Bachelor’s degree in English, Technical Communication, Journalism, Communications, Business, Engineering, or a related field.
