Plinth.org.uk is a fast-growing London-based platform powering £55 million in annual charitable funding for over 1,500 organizations.

You will build a comprehensive platform used by 1,500+ charities to manage grants, safeguarding, and reporting. Working in a high-autonomy team of 15, you’ll own features from ideation to production.

- You have complete freedom to define your own role and use any AI tools you prefer, supported by a leadership team that values mission-driven output over years of experience.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Write clean, scalable TypeScript code across the full stack using React and Node.js to solve complex problems for foundations and local charities.
- Architect and build new features like grant management systems, AI impact reporting, and safeguarding tools from initial concept to production maintenance.
- Build sophisticated migration tools to help charities transition from manual spreadsheets and legacy systems onto Plinth.org.uk’s unified system of record.
The ideal candidate
- A capable generalist with multiple years of experience shipping production code and managing complex systems, ideally having owned products from end-to-end.
- Strong proficiency in React and TypeScript is essential, with additional experience in Node.js and Elasticsearch considered a significant advantage for this role.
- A mission-driven individual who values "childish enthusiasm" and transparency, preferably with previous experience or a deep interest in the charity or non-profit sector.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
