Mid-senior level

About the Role

As Development Manager you will build and run the fundraising engine that powers our campaigns. Bold, disruptive campaigning needs fuel — and you will make sure Slingshot has it, by running excellent fundraising operations, crafting compelling grant applications, and building genuine relationships with the individuals who fund our work.

You will lead on fundraising logistics and systems — including our donations platform — so that giving is easy, data is clean, and nothing falls through the cracks. You will draft grant applications that tell our story with clarity and force, and you will deliver the communications that turn one-time supporters into long-term partners in the fight to end factory farming.

You will work in close partnership with our Co-Founders, who lead major donor relationships and set our overall fundraising direction. Your job is to turn that direction into a working pipeline, a reliable system, and a steady flow of income.

This role suits someone who is equally comfortable in the detail (deadlines, data, platforms) and in the story (donor communications, grant narratives, cultivation) — and who understands that every dollar raised is pressure applied to Big Ag. In time, this role will likely evolve to a director-level position as our fundraising function grows, with expanded responsibilities engaging with major donors.

About the Organisation

Project Slingshot is a bold new global initiative launching in 2026 with one mission: to end factory farming. We do this by exposing the lies, cruelty, and power of Big Ag through disruptive campaigns that cut through the noise, capture public attention, and build unstoppable momentum for change. We’re unapologetic, fast-moving, and impact-driven. We don’t just want to participate in the conversation — we want to change it.
