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.
Who this is a fit for
- 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.
Why this role is remarkable
- Join a high-leverage engineering culture with no PMs, no daily scrums, and a “never the delay” mentality that prioritizes shipping quality software over bureaucracy.
- The platform is experiencing massive traction, managing £55 million in annual funding with 4x year-on-year growth and a user base of over 1,500 charities.
- 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.
