 About Fundraise Up
 
 
 
 We&rsquo;re Fundraise Up - a global fundraising platform built to make donating to nonprofits fast, seamless, and accessible to all. Every month, our technology powers tens of millions of dollars in donations across the globe. We focus on innovation that directly impacts results: faster load times, higher conversion rates, global payment support, and accessibility-first design.
 
 
 Our platform is trusted by many of the world&rsquo;s leading nonprofits, including UNICEF, the Alzheimer&rsquo;s Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, we&rsquo;re recognized not just for our impact - but for the quality of the product we deliver.
 
 
 A Truly Global Product
 
 
 We operate in the enterprise segment, serving nonprofit organizations across North America, the United Kingdom, Australia, and Europe.
 
 
 We&rsquo;re building a large and complex product ecosystem that serves nonprofits, donors, and partners around the world. The platform includes a modern checkout experience and customizable widgets (each a standalone SPA), donor, organization, and partner portals, admin tools, and several internal apps.
 
 
 Our backend is powered by Node.js (Koa, NestJS) and MongoDB. The frontend stack includes Webpack, Vue.js, and React, with nearly all code written in TypeScript. For high-throughput messaging and background processing, we use Kafka (for millions of events) and Bull (Redis). Analytics data is stored in ClickHouse, and we use Elasticsearch for search.
 
 
 The Team
 
 
 We are a distributed team of 160+ product professionals, including 80+ engineers. Our team members are mainly based across Spain, Poland, Portugal, Georgia, Armenia, Serbia, Turkey, and Cyprus. Many of our developers bring 5 - 10+ years of experience, and we foster a culture of deep technical curiosity and knowledge sharing.
 
 
 Despite our scale, we operate like a focused team - where every task matters and every voice is heard. We value thoughtful collaboration, strong engineering practices, and a product mindset. Biweekly engineering forums give space to share learnings and celebrate technical achievements. You&rsquo;ll be joining a team where quality, mentorship, and mutual respect come first.
