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 The best internal tools disappear — they just make everyone else faster. As our Tools Engineer, you'll build and maintain the automations, bots, and AI assistants that quietly remove routine work across the company. This is a generalist, fullstack-with-backend-bias role: you'll touch our project-management system, Slack and Telegram, and a growing set of AI-powered assistants, and you'll be trusted to decide how each problem should be solved. It's distinct from QA automation — your mandate is internal productivity, not test infrastructure. Key Responsibilities Own internal automation for our project-management system (TargetProcess) — building custom rules, workflow logic, and integrations with other internal systems. Design and ship bots for Slack and Telegram that carry out real work — creating tasks, delivering notifications, and answering routine requests. Automate recurring operational processes — on-call/duty announcements, absence notices, reminders, and similar workflows that would otherwise need manual attention. Build AI-powered assistants and agents that help employees get fast, accurate answers and complete routine tasks. Build lightweight internal mini-projects that support company events and culture (for example, a prediction/betting site for New Year). Document every solution you ship — what it does, how it works, and how to operate or extend it — so tools stay maintainable and don't depend on any one person. At Fundraise Up, AI is a default tool, not an experimental one. We expect every team member to actively use AI in their day-to-day work, identify where AI can change the shape of problems in their function, and grow their fluency as the tools evolve. Skills and Qualifications 5+ years of professional software development experience, including automation, bot development, and process automation Fullstack capability with a clear backend bias Strong knowledge of JavaScript/TypeScript and Node.js Experience with at least one modern frontend framework (React, Vue, Angular, Svelte, or similar) Experience with serverless platforms (Cloudflare Workers, Vercel, or equivalent) Experience with MongoDB, ClickHouse, and/or PostgreSQL — comfortable working across both relational and non-relational databases Practical experience building bots for Slack and/or Telegram Hands-on experience automating processes and integrating third-party APIs Working knowledge of OpenAI/LLM APIs Able to work autonomously, make decisions, and own outcomes without close supervision Reliable in honouring commitments and agreements English proficiency sufficient for daily written and verbal communication Able to maintain strong availability/responsiveness during 12:00–18:00 CET, even on a flexible part-time schedule Nice to Have Experience building RAG pipelines or agent-based systems You'll Thrive Here If You… You'd rather build the tool that removes the work than do the work by hand You're comfortable owning a wide, shifting surface of systems with no single "home stack" You take documentation seriously — you write it so someone else could pick up your work tomorrow You can be handed an ambiguous "this is annoying, fix it" problem and turn it into a shipped automation You're reliable by default — if you commit to something, it happens You like the flexibility of part-time contract work but don't use it as an excuse to be hard to reach You're curious about AI tooling and treat it as a working part of your toolkit, not a side experiment Compensation €36,50 – €39 per hour , based on 10–20 hrs/week. **Please note: All official correspondence from Fundraise Up will exclusively originate from the @fundraiseup.com domain.
