About the role
The Senior Mobile Engineer joins us to own the Customer App technically: architecture, performance, offline capability, and the Flutter engineering standards that will serve SarvaGram as the app grows from its current state to a full -feature platform.
Flutter is technology. Rural India is the user base. The intersection of those two facts means this role requires both technical depth (performance engineering, offline -first architecture, low -end device optimisation) and the empathy to build software for users who may be accessing the internet for the first time on a low -end smartphone in a village with intermittent connectivity.
Key Responsibilities
Customer App - Technical Ownership
• Own the Customer App architecture - Flutter project structure, state management approach, navigation patterns, API integration layer, and the architectural decisions that will govern the app for the next three years
• Conduct a full technical audit in the first 30 days - document the current state, identify performance bottlenecks, security gaps, offline capability limitations, and technical debt that needs remediation
• Own the app performance budget - define acceptable load times, memory consumption, battery usage, and APK size targets for a rural user on a low -end Android device, and build to those constraints
• Implement offline -first architecture - local data caching, sync strategies, conflict resolution, and the graceful degradation patterns that keep the app functional during connectivity drops
• Own the app release process - Play Store release management, versioning strategy, staged rollouts, and the A/B testing infrastructure for feature experiments
WhatsApp Integration & Lending Flows
• Own the mobile -side WhatsApp integration architecture - how the Customer App and WhatsApp channel share state, handoff flows, and deep link handling for the agentic lending workflows being designed
• Implement the loan application journey in Flutter - the full origination flow from lead capture through KYC, document upload, and application submission; designed for rural users with variable literacy and connectivity
• Build the repayment and EMI management UIs - payment flow, BBPS integration, eNACH mandate management, and the notifications that drive on -time repayment behaviour
• Implement the field officer mobile tools - the screens that field officers use for customer onboarding, visit documentation, and collections activity capture in the field
Rural UX & Performance Engineering
• Build for low -end Android devices that SarvaGram's borrowers use require deliberate performance engineering; this is not a nice -to -have,



it is the primary performance constraint
• Design for low -literacy users - icon -first navigation, voice input support, regional language readiness (Marathi, Hindi), and the interaction patterns that work for first -time smartphone users
• Implement progressive loading and skeleton UIs - perceived performance patterns that make the app feel fast even on 2G connections by loading critical content first
• Own crash reporting and real -user monitoring - Firebase Crashlytics, performance monitoring, and the analytics that tell you how real users in rural Maharashtra and Karnataka are experiencing the app
AI -Native Mobile Development & Standards
• Use Cursor / Claude as primary development tools - AI -assisted Flutter development is the engineering standard; widget generation, state management boilerplate, and test writing are AI -augmented
• Design the AI feature integration on mobile - how the WhatsApp AI agent, agentic underwriting flows, and AI -generated personalisation surface in the Customer App UI
• Define Flutter engineering standards for Nexus - code organisation, widget composition patterns, state management approach, testing strategy, and the review criteria that govern all Flutter code
• Mentor the Mobile Engineers - structured development toward ownership of feature domains and eventual independence on production deployments
Requirements
Professional Experience
• 6 to 8 years in mobile engineering with 3+ years in Flutter - has shipped production Flutter apps with real users and managed the full lifecycle from architecture to Play Store release
• Has engineered for constrained devices and connectivity - has worked on an app where device capability and network quality were genuine engineering constraints, not edge cases
• Has owned mobile architecture decisions in a production app - not just implementing features but making the architectural choices (state management, offline strategy, navigation) that the team lives with
• Active AI tool user - uses Cursor and Claude for Flutter development today; AI -augmented development is standard practice
• Fintech mobile experience is a meaningful plus - payment SDK integration, KYC flows, and bureau API mobile surfaces are common territory




Mindset & Soft Skills
• Rural empathy: Rural user empathy: the app's users are not developers or urban smartphone power users - designs for the actual user, not the imagined user
• Performance obsession: Performance obsession: a feature that works beautifully on a Pixel 8 but is unusable on a Redmi A2 has not shipped for SarvaGram - performance on low -end devices is the acceptance test
• Technical ownership: Technical ownership: 'I inherited this codebase' is not an excuse - audits, fixes, and refactors are the Senior ME's responsibility from week one
• AI -native: AI -native developer: reaches for Claude before writing Flutter boilerplate or writing documentation - AI -augmented mobile engineering is standard, not occasional
