About ChangeX

We are ChangeX. We have built a platform to connect communities to proven ideas and funding to scale sustainable impact.

Our mission? To empower people everywhere to change their communities for the better by making it easy for them to access the ideas, funding and support they need.

With our support, great ideas like Grow it Yourself, Girls Who Code, Repair Café, EasyPeasy Pods and FIRST LEGO League, are being adopted by communities across the world.

Our team and how we work:

We are simplifying and accelerating the way people fund, start and grow projects in their communities. We’re looking for engineers who share our belief in the power of great technology to transform lives.

Remote working is part of our company’s DNA. For example, our development team currently works remotely, with team members in Ireland, Spain and Brazil.

As a development team, we run a lightweight process that focuses on feature-based delivery on a weekly basis. Our coordination and communication are mostly through daily ‘catch-up meetings’ and use of appropriate tools such as Trello for backlog management, Slack for communication and Git(GitHub) for source control and feature deployment through PRs and Milestones.

We make use of peer review for all design and development work. In general, we strive for an approach that empowers and trusts individuals to ‘do the right thing’.

This role: Full Stack Software Engineer

The role is an opportunity for a mid to senior level developer to be part of the core Product team that scales ChangeX over the coming years.

We are currently going through an exciting growth phase, evolving from a traditional RoR architecture to additionally support a modern “single page application” approach. This evolution exposes our application as a set of APIs consumed by React to provide a rich interactive experience.

As part of this project, you will work on re-building the fund-management UI in our application.

Examples of projects you might work on:

  • Build new features that bring the impact of community projects to life, including dashboards, feeds and APIs to highlight deeply insightful data
  • Work closely with the rest of the Product team to improve existing features, based on feedback from our users
  • Upgrades to our tech stack – we like to stay up to date with our frameworks
  • Refine our existing processes to thrive at scale, innovating and finding areas to automate 

We are looking for people* who have:

  • Experience working across the entire stack (Ruby on Rails, Javascript, PostgreSQL), ideally
  • Strong experience with React or similar Javascript-based libraries
  • Some UX and design sensibilities
  • Strong programming skills with a focus on clean design, well-refactored code and automated testing
  • Confidence playing a significant role in the vision and development direction of the product
  • A demonstrated commitment to social change
  • Strong empathy and ethical fibre

*We encourage you to apply if you believe your skills and experience are a good fit for this role, even if you don’t tick every box above. When making hiring decisions, we aim to be inclusive and look beyond checklists. We want to find people who bring fresh perspectives and want to grow with our organisation.

Technologies we use:

  • Ruby on Rails is our primary server framework
  • React
  • Deployed using Heroku for managing infrastructure
  • PostgreSQL Database
  • GitHub for source code management and process support
  • GitHub Actions for continuous integration


  • 25 holiday days per year plus flexible hours
  • Flexible working options: remote, in office or a hybrid 
  • Annual performance related bonus
  • Pension scheme 
  • Basic health insurance plan
  • Master new skills from those around you with onsite/online talks and networking at our hubs
  • Access to a great work environment and facilities in Dublin, New York or a co-working space convenient for you
  • Annual team retreat
