About the Role
We are looking for a Senior Android Engineer with deep React Native expertise to build and own the trading
experience on Android — real-time data, interactive charting, fluid interactions, and rock-solid performance. What We’re Looking For
You have shipped production React Native apps that handle real-time data streams, complex UI states, and
performance-sensitive rendering. You understand the Android platform deeply — native modules, bridge
performance, and platform-specific behaviour. Ideally, you have worked on trading, fintech, or data-intensive
mobile products. You take ownership of your features end-to-end, care about code quality, and are comfortable
driving technical decisions independently. What You’ll Do
• Own the mobile trading experience on Android — architecture, performance, and end-to-end quality. • Build and optimize real-time data rendering — WebSocket lifecycle management, efficient list rendering, and minimal re-renders for streaming data. • Integrate complex WebView-based components with bidirectional JavaScript bridge communication. • Collaborate with product and design to deliver polished, intuitive interfaces for a financial product where
trust and clarity are paramount. • Define mobile engineering standards — component architecture, state management patterns, testing
strategy, and performance benchmarks. • Drive code reviews, mentor team members, and champion best practices across the mobile team. • Participate in stabilization and release cycles — profiling, device matrix testing, and regression analysis. Must-Have
• 4+ years React Native experience with production apps on Google Play Store. • Strong TypeScript skills and deep understanding of React Native internals — bridge, native modules, and
performance optimization. • Experience with real-time data handling — WebSockets, efficient UI updates for streaming data, and
state synchronization. • Experience integrating WebView-based components with JS bridge communication. • Proficiency with state management at scale (Redux, Zustand, or MobX).
• Experience with push notifications (FCM), deep linking, and complex navigation patterns. • Strong debugging skills — Flipper, React DevTools, native crash analysis, and performance profiling. Nice-to-Have
• Prior experience building trading, brokerage, or fintech mobile apps. • Experience with charting library integration in mobile apps. • Knowledge of server-driven UI (SDUI) patterns. • Experience with feature flags, A/B testing frameworks, and app modularization. • Familiarity with native Android development (Kotlin) for bridge modules.

Software Engineer - Mobile (SDE 3)
Own mobile features from architecture to production.
AbleCredit builds software for complex enterprise workflows where AI, APIs, business rules, human decisions, and real-world operations have to work together reliably. We care about building products that work in production - not just in demos. Our mobile applications operate in the real world: variable networks, device fragmentation, media capture, background work, permissions, and workflows that cannot simply fail when connectivity does. We're looking for an engineer who can independently own substantial parts of that experience.
What You'll Own?
• Design and ship major mobile features end-to-end, from technical design through production rollout.
• Build reliable experiences around camera, audio, media upload, location, permissions, and device capabilities.
• Design for poor connectivity, retries, offline behavior, background execution, and interrupted workflows.
• Own API integration, local state, caching, persistence, and synchronization patterns.
• Improve app startup time, responsiveness, battery/network usage, crash rate, and overall reliability.
• Build observability into mobile features and debug issues across device, network, and backend boundaries.
• Contribute to mobile architecture, testing strategy, release engineering, and technical standards.
• Mentor junior engineers and interns through reviews and design discussions.
What We're Looking For?
• 5+ years building production mobile applications.
• Strong experience with Android/Kotlin, iOS/Swift, Flutter, React Native, or comparable mobile stacks.
• Deep understanding of mobile lifecycle, networking, concurrency, persistence, and performance.
• Experience shipping and supporting applications through production releases.
• Strong debugging skills using device logs, profiling, crash reporting, and network inspection.
• Good API design instincts and ability to reason about backend/mobile contracts.
• Ability to independently turn ambiguous product requirements into robust technical solutions.
Nice to Have
• Media capture or real-time audio/video experience.
• Offline-first or field-workforce applications.
• Mobile security, encryption, device integrity, or secure storage.
• Native module/bridge development in a cross-platform application.
• Experience with mobile CI/CD, automated testing, staged rollouts, and release observability.
How We Build?
Mobile is not a thin client. We treat device behavior, network reliability, telemetry, performance, and release safety as core engineering concerns. Engineers own what they ship after it reaches production.
