We’re looking for a Full Stack Developer to join the ChangeX team

Role: Full Stack Developer

Location: Dublin, Ireland

Role Status: Full Time

Remuneration: Based on Experience

About ChangeX:

ChangeX is a marketplace connecting proven ideas for strengthening communities with teams who start them locally and those with the resources to support – ideas like Grow it Yourself, Mens Shed’s, Repair Café, CoderDojo and Playworks, adopted and started by teachers, healthcare professionals, community workers and other proactive citizens.

There are thousands of social innovations across the world that have been proven to work, but too few at global scale, leading to wasteful reinvention or worse, no solution at all.  Technology can address this. We’re on a mission to help build thriving communities everywhere – in our first three years, over 180,000 people have benefitted from 5,000 new projects started on ChangeX.

Our business model is called Impact as a Service – we make it easy for funders to find and invest in the ideas they want to spread in regions they care most about.  Our philanthropic backers come from some of the best recognized venture firms including Andreessen Horowitz, Union Square Ventures and Insight Ventures as well as founders like Mike Lee (MyFitnessPal), Colm Lyon (Fire) and Jerry Greenfield (Ben & Jerry’s).

Our team is based at Dogpatch Labs in Dublin with team members in the U.S. and Europe.
