About Fundraise UpWe'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 ProductWe 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 TeamWe 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. 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.
About the Mobile TeamYou'll join the mobile team inside our Engineering department. The team builds the products that let nonprofits accept donations in the physical world. Tap to Donate lets a staff member or volunteer accept contactless payments directly on a smartphone. Giving Station is a self-service donation point: a donor selects an amount on a tablet and pays through a connected external payment terminal.
Our mobile stack:- bare React Native (0.79, Old Architecture)
- React 19, TypeScript
- React Navigation 7, TanStack Query 5, React Context
- react-hook-form, Zod
- an internal UI Kit built with twrnc
- Stripe Terminal, Tap to Pay, external payment terminals
- Sentry, PostHog
- Node.js, NestJS, React, MongoDB, ClickHouse, and Redis across the backend and web stack
About the RoleYou will design, build, and maintain the mobile applications that power Fundraise Up's product on iOS and Android. Mobile is the primary focus, with contributions extending to the backend and web frontend the product depends on to deliver features end-to-end. You'll work across the full development lifecycle - from requirements analysis through implementation, testing, store release, and production support - and ensure the applications are reliable, performant, and secure across the devices and OS versions in use.
What You'll Do- Implement features, fix bugs, and resolve production incidents across iOS and Android, extending to the backend and web frontend the product depends on - delivering tested, production-ready output that meets the team's quality bar.
- Own mobile initiatives end-to-end - gather requirements, design the approach, decompose into tasks, implement, and deliver to production across iOS and Android, including the backend and web frontend changes they require.
- Act as the team's primary technical escalation point for complex mobile problems - diagnose root causes across the app, native layers, networking, and platform behavior, and prevent recurrence.
- Review code and designs for correctness - component and navigation structure, rendering, native integration, and alignment with mobile patterns - catching issues before release.
- Contribute to and evolve mobile engineering standards within the team - component architecture, native integration, testing, and release policy.
- Monitor the operational health of shipped work - track releases and staged rollouts, watch release health, and respond to post-release issues on both platforms.
Requirements- 8+ years of professional software development experience, including 3+ years with React Native.
- Proficiency in React Native and TypeScript - the primary craft.
- Strong JavaScript fundamentals - asynchronous programming, event loop behavior, error handling.
- Working knowledge of relational and document databases - data modeling, querying, indexing.
- Understanding of RESTful API design and HTTP fundamentals - able to work across Node.js backend services, API contracts, database queries, and web frontend code.
- Familiarity with the native iOS and Android platforms and their tooling (Xcode, Android Studio, Gradle).
- Understanding of mobile OS fundamentals - app lifecycle, background execution, permissions, and memory constraints.
- Experience with automated testing practices (unit, integration, E2E).
- Understanding of mobile security - secure storage and handling of sensitive and payment data.
- Confident day-to-day use of AI-assisted development tools - for research, troubleshooting, and implementation.
- Ability to independently diagnose common React Native production issues - rendering, navigation, networking, and app lifecycle.
- Track record of owning mobile initiatives end-to-end - from requirements through store release, including the backend and web frontend changes they require.
- Experience designing mobile application architecture - trade-offs in performance, reliability, and observability across iOS and Android.
- Experience designing or integrating native modules and SDKs where React Native abstractions are insufficient - including focused Swift/Kotlin changes and debugging across the JavaScript and native layers.
- Experience owning the release process - app signing, store submission, and staged rollouts.
- Experience establishing mobile engineering practice from little - standards, CI/CD, and release - across inherited and greenfield codebases.
- Experience designing resilient asynchronous and event-driven backend interactions (messaging, queues).
- Experience with mobile production operations - monitoring, crash reporting, incident response, and rollback policy.
- Demonstrated ability to mentor and develop less experienced engineers.
- English proficiency sufficient for daily written and verbal communication.
Nice to Have- Broader backend and database experience.
- Experience with event-driven architectures and asynchronous messaging patterns.
- Experience operating high-traffic, low-latency systems.
- Experience with offline-first architectures and data synchronization over unreliable networks.
- Familiarity with React Native's New Architecture (JSI, Fabric, TurboModules, Codegen) and the native library compatibility constraints of migrating to it.
- Native development depth in Swift and/or Kotlin beyond React Native.
- Experience with in-person or mobile payments and fintech products.
- Experience with Stripe Terminal, Tap to Pay, or NFC.
- Experience in a distributed, remote-first engineering organization.
