About Fundraise Up
Weāre 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 worldās leading nonprofits, including UNICEF, the Alzheimerās Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, weāre 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.
Weāre 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. Youāll be joining a team where quality, mentorship, and mutual respect come first.
About The Role
As a Senior Fullstack Developer, you will be a key contributor to our core product, building and scaling features that are central to the donation experience for millions of users. You'll leverage your expertise in Node.js, React, and TypeScript to develop complex componentsāfrom dynamic donation widgets to data-driven admin dashboardsāwith a relentless focus on code quality, scalability, and user experience.
This is an ideal opportunity if you love solving real-world problems at scale and want to grow within a mission-driven, high-impact engineering culture.
