We’re Looking For

Someone who can contribute to creating and enhancing a user-friendly app that seamlessly connects sellers, buyers, and charities. 

You’ll play a vital role in helping us scale our platform to maximise its impact, empowering users to support their favourite causes with ease.

Key Responsibilities

App Development: Build, enhance, and maintain cherry’s (yes, with a lowercase ‘c’) mobile app using Flutter and community-led best practices. Focus on completing the MVP journey; from listing and basket to payment, order confirmation, and in-app tracking.

Collaboration: Work closely with team leads, backend developers, and designers to ensure the app reflects cherry’s mission, vision, and user needs. Align work with the roadmap and help keep the app demo-ready for grants and partnerships.

User Experience Design: Create an intuitive, accessible, and visually consistent experience across all screens. Support ongoing UI polish for clarity, contrast, and ease of navigation.

Backend Integration: Connect the app to secure APIs and backend services for authentication, product creation, checkout, and Stripe test-mode payments. Ensure a smooth data flow and stable functionality throughout.

Debugging and Maintenance: Troubleshoot and resolve issues raised during testing. Help identify bugs, gaps, and usability improvements, keeping the app reliable for testers and demonstrations.

Scalability and Performance: Write clean, modular code that supports future growth. Optimise performance and ensure builds are light, fast, and ready for wider testing.

Documentation and Version Control: Follow cherry’s collaborative workflow on GitHub. Link commits to issues, use clear branch naming, and document any changes affecting user flows in Notion or the README.

Why Join Us?

• We are a startup charity. With your help, we can make this happen. If you see how important this is and stay with us, your contribution WILL be remembered when paid roles open.
• Be part of a purpose-driven organisation making a REAL solution for charities and the destruction caused by the fashion industry!
• Gain hands-on experience with an impactful startup charity tech project.
• Help create a 100% digital charity to save all charities!
• Collaborate with a passionate, committed diverse yet unified team!
• Solid verbal/ written references.

What are we looking for?

We’re looking for someone who enjoys building things that matter. 

Nothing is stronger than the heart of a volunteer.

If it's purpose that deep down you are looking for, I personally, as the Volunteer Director, could not think of a greater one.

You don’t need to have all the answers, just curiosity, reliability, and a genuine wish to help create something objectively good. We welcome developers of all abilities, and would always rather a proactive learner than a lazy knowitall (...though yes, all are still welcome)!

You’ll be joining a small-medium, 100% volunteer driven and open team where ideas are shared freely and learning is encouraged.

A mix of technical confidence, a positive, can-do attitude and a desire for meaning over money, purpose above power, will solidify you in our cause; to which I truly believe there is not much of higher importance. 

We cannot let charity die in the future to come.

• !!! - Technical Expertise: Experience in mobile app development (iOS, Android, or cross-platform frameworks such as Flutter or React Native; Node.js for backend is also ideal).
• !! - Backend Knowledge: Experience with APIs, databases, and cloud services; ideally familiar with Stripe and Firebase.
• !! - Problem Solving: Good debugging and troubleshooting skills.

Skills that help

• Experience using Flutter/ Firebase/ Node.js/ Stripe.
• Understanding of API integration and how data moves between the front and back ends.
• Some awareness of UI/UX principles and using Figma or similar tools (EG: for reference).
• Comfort using GitHub and following clear, collaborative workflows.
• A good eye for detail, especially when testing or fixing issues
• Problem Solving! (EG: we're currently stuck in darkmode and there are some fixable errors, pls help🥺) 

Qualities that matter most

• Purpose-driven: You care about sustainability, community, and using your skills for good!
• Collaborative: You can listen to, share with, and support others.
• Adaptable: You can work with changing momentums and stay calm and ready when things shift.

• Creative: You enjoy finding simple, clever ways to solve problems.

If you’re excited by the idea of helping build an open-source, charity-first app and want to gain hands-on experience in a real solution to the biggest problems, this is for you. 

You’ll be part of a purpose-driven, friendly team creating something that can make 3rd world exploitation/ "clothing canyon" landfills (🖕) harder, and make giving personal and accessible for everyone.

What difference will you make?

We are a team of 40+ volunteers, diverse in all ways, all purposes and experiences, yet unified by that which can only work if YOU want it to enough that you choose to help us NOW!

Right now, cherry is preparing its app for live demonstrations, the final step before sharing our work with partners, funders and charities. 

By joining us, you will help turn a functional MVP into a polished, reliable, easy-to-pitch platform that shows exactly how the future of giving can be effortless and open/ transparent!

Your work will help complete key features such as payments, checkout, and in-app order tracking. 

These are the milestones that will allow us to demonstrate cherry’s full potential and prove that our model works for charities of every size.

Each contribution, from testing and debugging to refining user flows, helps build confidence in the platform and ensures a smooth experience for everyone who uses it. 

Together we are creating open-sourced charitable technology that connects not simply people, but generosity with REAL impact, helping people give easily, sustainably and with genuine trust!

Before you apply

Once you apply through Reach, we’ll review your message, CV and any linked work such as your GitHub, LinkedIn or portfolio. What matters most to us is seeing genuine interest in our mission and a basic sense of your technical background.

We’re not expecting perfect portfolios or years of experience (...though we of course welcome it). Instead, we’d love to know why you want to help build cherry, what areas of development interest YOU most, and how you’d like to grow through the project?

If your profile fits what we’re looking for (I know it will), we’ll invite you to an informal chat online. These usually last around 20–30 minutes and give us both a chance to get to know each other, talk through the project, and see where your skills would fit best.

We review applications on a rolling basis and aim to reply within 7–10 days of receiving your message. 

After the chat, we’ll confirm your next steps and connect you to the team spaces; so you can start contributing at your own pace.

All volunteers are warmly welcomed into our collaborative, open-source community, where kindness, curiosity and initiative are valued above all else.
