This position plays a critical dual role in both writing and managing the proposal development lifecycle. The ideal candidate will not only craft compelling, compliant, and persuasive responses to government and commercial solicitations (RFPs, RFIs, RFQs), but also manage the proposal schedule, coordinate inputs, and drive team collaboration—ensuring timely, high-quality submissions.
This position requires excellent writing, editing, coordination, and scheduling skills, along with a solid understanding of federal, state, and local procurement processes.

RESPONSIBILITIES

• Develop compliant and persuasive proposal content including executive summaries, technical and management approaches, past performance, resumes, and pricing narratives.
• Collaborate closely with subject matter experts (SMEs), capture managers, and proposal teams to gather information and refine content.
• Translate complex technical concepts into clear, concise, and audience-tailored proposal responses.
• Lead and manage proposal coordination activities, including developing and maintaining proposal calendars, Color Team schedules (Pink, Red, Gold), and internal deadlines.
• Schedule and facilitate proposal meetings, track action items, and ensure accountability across team members.
• Edit and proofread proposal content for clarity, compliance, consistency, and grammar.
• Maintain and update a content library including boilerplate responses, corporate capabilities, past performance summaries, and reusable assets.
• Assist with development of visuals, tables, and infographics that enhance written content.
• Manage proposal submissions and support final packaging and delivery in accordance with solicitation requirements.
• Monitor industry trends and update proposal strategies and materials with best practices.
• Support compliance tracking and ensure alignment with Shipley or APMP-aligned processes.
• Participate in and coordinate Color Team reviews, incorporate feedback, and track review outcomes.

QUALIFICATIONS

• Bachelor’s degree in English, Journalism, Communications, Marketing, Business, or a related field.
• 3+ years of experience writing and coordinating government and/or commercial proposals (Federal, State, Local preferred).
• Proven experience with proposal management and coordination, including scheduling, tracking inputs, and facilitating team communication.
• Familiarity with proposal development methodologies such as Shipley or APMP.
• Strong writing, editing, communication, and organizational skills.
• Ability to manage multiple projects simultaneously in a fast-paced, deadline-driven environment.
• Proficiency with Microsoft Office (Word, Excel, PowerPoint), Adobe Acrobat, and tools such as SharePoint, Teams, RFPIO, Loopio, or similar.
• Familiarity with GSA Schedules, IDIQs, BPAs, and federal acquisition regulations is a plus.
• Experience with NASA SEWP, GSA MAS, or other contract vehicles is a bonus.
