О компании и продукте

• 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. 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 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.
• bare React Native (0.79, Old Architecture)
• React Navigation 7, TanStack Query 5, React Context

Задачи

• 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

Требования

• 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

Будет плюсом

• 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
• 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

Условия

• 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
• Long-term focus: we offer equity options and value sustained, meaningful contribution
