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’s leading nonprofits, including UNICEF, the Alzheimer’s Association, and a wide range of global NGOs. With a 4.9/5 rating across top software review platforms, we’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’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. You’ll be joining a team where quality, mentorship, and mutual respect come first. ## About the Role As a Backend Engineer, you will be a key architect of the engine that powers our global platform.

Bonus points - Curiosity and a hypothesis-driven mindset - Ability to communicate complex analytical concepts to non-technical audiences - Detail-oriented with a strong sense of ownership - Comfort working in fast-paced, data-rich environments ## Why work with us - A strong, collaborative product team that owns what it builds. - Clear product vision and access to real customer feedback from global nonprofit leaders. - Flat structure: no politics, just great work with great people. - Transparent company culture-we share how we’re growing, where revenue comes from, and what’s next. - Long-term focus: we offer equity options and value sustained, meaningful contribution. ## Compensation - The compensation range for this role is: $4,700 - $5,500 gross per month. - Final compensation will be determined based on relevant experience, skills, qualifications, and alignment with the role's requirements. ## Benefits - 31 days off. - 100% paid telemedicine plan. - Home Office Setup Assistance: the company offers assistance with purchasing furniture (office chair, office desk, monitor) and other items to create a comfortable workspace. - English learning courses. - Relevant professional education. - Gym or swimming pool. - Co-working. - Remote working. **Please note: All official correspondence from Fundraise Up will exclusively originate from the @fundraiseup.com domain.
