Job Opening: Full Stack Developer


A bit about us

ActionFunder has been built by the team behind Semble, the BCorp that brings businesses and communities together to make change happen from the grassroots up. Over the last 10 years we have run dozens of campaigns for major UK brands such as Persil, Carling & Iceland Foods and have established a network of 3500 community organisations doing brilliant work all around the UK. We have a highly motivated team who work really hard and are fiercely proud of what we do and the positive change we have enabled. But we are restless to do more – to scale up and multiply our impact.

During the pandemic we saw the devastation wreaked on small but vital charitable organisations and this triggered us to build a game-changing new platform. We fundamentally believe in the power of business to do good and to that end, our new platform, ActionFunder, changes the way in which businesses and community groups connect.

ActionFunder makes it quicker and easier to give and get funding. It reduces the cost of giving for businesses and provides better, simpler access to funding for grassroots groups.

We have run a successful 6 month Beta trial, partnering with 16 Funder organisations and launched publicly in October. We have ambitious growth plans and need passionate and knowledgeable developers to join the team and help us further develop the platform.
