Highlights: Location: Remote (CET hours preferred) Language: Russian-speaking team About Fundraise Up We’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’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 resolve complex challenges in a high-load, distributed system, building and scaling the infrastructure that processes millions in donations. This is not a maintenance role; it's a high-impact, product-focused engineering position where clean architecture, performance, and reliability are paramount. You will work on a complex product ecosystem—from our modern checkout experience to donor portals and massive analytics pipelines—all powered by a cutting-edge tech stack. Backend: Node.js (Koa, NestJS), TypeScript Database: MongoDB Infrastructure: Kafka for event streaming, Bull (Redis) for background jobs, ClickHouse for analytics, and Elasticsearch for search.

Write comprehensive unit tests and conduct thorough code reviews to maintain code quality. Proactively identify and implement system improvements, refactoring legacy code where necessary. Contribute to a culture of engineering excellence by mentoring others and sharing your expertise. 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. You should already be using AI meaningfully in your work and understand where it adds value and how it can improve the way you operate. Requirements Experience: 7+ years of backend development experience, preferably in a product-driven environment.

Data & Search: Hands-on experience with ClickHouse (or similar analytics DBs) and Elasticsearch. Architectural Mindset: A strong understanding of system design, clean architecture principles, and performance optimization. Ownership: The ability to work independently, take ownership of your work, and see projects through to completion. Communication: Comfortable working within a Russian-speaking team. Nice to Have Prior experience working in a remote-first, globally distributed team. Experience with performance monitoring and observability tools (e.g., Prometheus, Grafana, Datadog).

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
