Job Summary

We are looking for a Senior Developer possessing 4-5 years of professional experience with a deep mastery of React Native, JavaScript, and TypeScript. The ideal candidate will have a proven track record of architecting and delivering high-quality mobile applications and is highly proficient in leveraging Supabase as a backend-as-a-service (BaaS) solution, bridging the gap between frontend mobile UI and scalable backend logic.

What you’ll do

• Lead the design and implementation of scalable application architectures, ensuring high-quality, clean, and maintainable code adhering to SOLID principles
• Architect and manage the backend infrastructure using Supabase, including database schema design, Row Level Security (RLS) policies, and Edge Functions
• Develop expertise in writing platform-specific code (Java/Kotlin for Android, Swift/Objective-C for iOS) and bridging native modules when necessary
• Identify and address complex performance bottlenecks (e.g., memory leaks, slow renders) using profiling tools to ensure 60fps UI performance
• Implement a robust testing pyramid including unit testing (Jest), integration testing, and end-to-end testing (Detox or Appium)
• Design robust asynchronous data synchronization and offline-first capabilities using Supabase and local caching strategies
• Provide technical guidance within the scrum team, influencing architectural decisions and long-term tech stack evolution
• Conduct rigorous code reviews, enforcing strict adherence to TypeScript patterns, security guidelines, and performance standards
• Maintain comprehensive documentation for system architecture, API contracts, and Supabase schema configurations
• Analyze user stories for technical feasibility and translate complex business requirements into technical tasks
• Provide accurate effort estimations and proactively identify technical risks or "technical debt" that may impact delivery timelines
• Communicate effectively with non-technical stakeholders, providing updates on progress and explaining technical trade-offs
• Actively mentor junior and mid-level developers, fostering a culture of continuous learning and professional growth
• Stay at the forefront of the React Native ecosystem (e.g., New Architecture/Fabric, Turbo Modules) and Supabase updates

Must Have

• Bachelor's degree in Computer Science, Software Engineering, or equivalent
• 4-5 years of hands-on experience focused on React Native development
• Proven experience in building production-ready apps from scratch, including backend integration and deployment to App Store/Play Store
• Advanced knowledge of PostgreSQL, including complex queries, indexing, and relational data modeling
• Experience implementing various authentication flows (OAuth, OTP, Magic Links) using Supabase Auth
• Deep understanding of Row Level Security (RLS) to ensure data privacy and secure multi-tenant architectures
• Experience with Supabase Realtime for live data syncing and presence features
• Proficiency in writing serverless logic using Deno/TypeScript for Supabase Edge Functions
• Management experience with file uploads and CDN delivery via Supabase Storage
• Expert proficiency in TypeScript and ES6+ JavaScript
• Deep experience with React Query (highly preferred for Supabase), Redux Toolkit, or Zustand
• Practical experience with native IDEs (Xcode, Android Studio) and bridging native libraries
• Exceptional verbal and written communication skills for cross-functional collaboration
• A proactive, solution-oriented mindset with the ability to navigate through ambiguous technical challenges
• Demonstrated ability to lead feature squads and take ownership of the end-to-end development lifecycle

Nice To Have

• Experience with EAS (Expo Application Services), Fastlane, or Jenkins for automated builds and OTA (Over-the-Air) updates
• Proficiency with Git (GitFlow), Jira, and debugging tools like React Native Debugger, Flipper, and Charles Proxy
• Experience with New Relic, Sentry, or Firebase Crashlytics for error tracking

What you’ll gain

• Paid time off and holidays.
• Professional development opportunities.
• On-site work with 5 working days per week
