Senior Grant Writer

About the Role - Senior Grant Writer As the Senior Grant Writer, you serve as the primary author and strategist for all grant proposals, letters of intent, prospective funding scenarios, and donor reports. You hold end-to-end accountability for the narrative quality, accuracy, strategic positioning, and timeliness of every institutional submission. Deeply attuned to funder priorities and the nuances of institutional philanthropy, you translate INP’s mission, community impact, and strategic vision into compelling, persuasive narratives that resonate with foundation and corporate partners. Reporting to the Director of Institutional Giving, you are an integral member of a collaborative seven-person development team. In this role, you steward an established institutional portfolio of roughly 30 local and national funders—representing gifts typically ranging from $100,000 to over $2 million and totaling more than $7 million in annual institutional support. Your responsibilities will include: Grant Writing & Submission: Write and submit approximately 30 proposals/LOIs and 30 reports annually (averaging just over one submission per week), crafting compelling narratives that reflect INP’s voice, mission, and strategic priorities. End-to-End Project Management: Own the grant lifecycle from initiation to final delivery, tracking deadlines, maintaining the master institutional giving calendar, and ensuring strict adherence to foundation guidelines. Cross-Functional Collaboration: Partner with program, finance, and executive leadership to source financial data, program metrics, and impact narratives needed for robust proposals and donor reporting. Prospect Research & Pipeline Development: Guide prospect research strategy and landscape analysis to identify and qualify up to $1M in new funding opportunities annually, partnering with Development Coordinators to execute detailed research and build out prospect profiles. What You’ll Need 7+ years of relevant professional experience, with a proven track record of writing successful institutional fundraising proposals. Exceptional writing and self-editing skills, coupled with an appreciation for a collaborative, team-based editorial process. Experience using Salesforce or a comparable CRM to log outreach, manage pipeline data, and track conversion milestones. Comfort leveraging modern workplace tools and AI applications to streamline communications and day-to-day operations. Ability to work gracefully under pressure, manage competing priorities, navigate ambiguity, and meet strict deadlines. Demonstrated ability to collaborate across functions while executing independently to achieve organizational fundraising goals. An authentic commitment to INP’s mission and a dedication to advancing diversity, equity, inclusion, and belonging. Who You Are An Effective Writer.
