• A system that empowers individuals through dignity and direct support

We're looking for someone who:

• Has solid experience with React Native and front-end development

• Can commit a few hours a week

• Is excited by social impact, ethical tech, and building something that matters

• Enjoys being part of a remote, collaborative, globally distributed team

��‍�� React Native Developer Volunteer – Join the Movement Behind MVP 2

Unify Giving is on a mission to change everything about giving — how it’s done, how it’s received, and how it’s perceived.

We’re building a world where people experiencing homelessness can receive digital donations with dignity, transparency, and choice — and we’re already live on the App Store. But now, we’re taking it further.

�� MVP 2 is here.
We’ve added powerful new features to give both donors and recipients the best possible experience — and we need your help to bring it to life.

✨ What you’ll do:

• Join our small but mighty team to help build and release MVP 2 of our React Native app.

• Collaborate with our designers, product leads, and community team to improve UX across the board.

• Work on meaningful features that directly impact people experiencing homelessness.

�� What we’re looking for:

• Experience in React Native, with solid understanding of mobile app dev (iOS & Android).]

• A belief that tech can be used for real, tangible good in the world.

�� Why it matters:

This isn’t just another side project. Unify Giving is already being used by real people across the UK. Your code could help someone access food, warmth, or support when they need it most.

�� What you’ll get:

• A chance to work on a live tech-for-good product.

• Your name in the credits (yes, we mean it).

• Weekly team check-ins, support from our founder, and full creative input.

• A front-row seat to building something that genuinely helps people — and is scaling fast.

About Bank.Green

Since the Paris Agreement, global banks have poured a staggering $6.9t into the fossil fuel industry. At Bank.Green, our mission is to lower this vast carbon footprint via technology and consumer action. We empower bank customers with the tools and insights they need to influence their banks towards sustainable lending, or switch to greener alternatives. To date, our bank-checking tool has been used over 500,000 times by bank customers worldwide, while we have shifted a at least $35,000,000 towards banks who are financing a greener future.

Through transparency, engagement, and innovation, we aim to redefine the role of banks in the fight against climate change.

Role Overview

We have a need for a senior Frontend Engineers to take ownership of the Bank.Green frontend website. The website is builtin Vue.js with Nuxt.js and deployed via Cloudflare. We use prismic.io as a headless CMS and connect to internal graphQL and REST APIs. Because of the large number of pages (~5000) we serve, we have to pay special attention to our prismic.io CDN traffic and caching with automated builds.

Taking ownership of the website will mean:

• understanding the vue.js lifecycle
• understanding cloudflare deployment
• understanding the nuxt build pipeline
• carefully authoring and reviewing PRs
• mentoring more junior frontend developers

For internal communication, we use slack, linear.app, and, when necessary, MS365.

Functionally, the website allows users to see how their current bank, and potential new alternative banks, rank on environmental issues - primarily fossil fuel and related sectors support. It also provides suggestions on how to talk to your current or potential future bank about your environmental concerns.

Commitment

This role is UNPAID and VOLUNTEER-BASED. We are seeking a commitment of 10-15 hours per week. We are looking for somebody to come on long-term, for at least a 3-6 month commitment.

We know that this a lot to ask. Bank.Green is a passion project of many people including other developers and data scientists. Many of our volunteers who are a) (f)unemployed and want to keep their fingers warm by doing something good for the world, b) otherwise trying to break into tech or environmental fields. We hope that you’re coming with some industry experience for this particular role.

Qualifications

• Proven experience as a Frontend Engineer, preferably in a mid to senior level capacity.
• Proficiency in JavaScript programming language.
• Familiarity with Vue.js + Nuxt is nice to have but experience with React+Next also works well
• Experience working with and mentoring more junior colleagues
• Experience working asynchronously with colleagues in different time zones - through Slack, MS Teams, or similar.
• Experience working in Agile environments and using collaborative development tools (e.g., Linear or Jira, Git).
• Strong problem-solving skills and attention to detail.
• Excellent communication and teamwork abilities.
• Passion for sustainability and environmental advocacy.
