React Native Developer - Supabase & Payment Integrations

SplitSense is a free, ad-free alternative to Splitwise that helps people manage group expenses, scan receipts, split individual items, merge balances, and simplify settlements.

We are looking for an experienced React Native developer who can work across the mobile application and its Supabase backend. Payment integrations and settlement flows are an important part of the role, but you should also be comfortable improving existing features, fixing bugs, and contributing thoughtful product ideas.

What you will work on

• React Native and TypeScript development across the SplitSense mobile app
• Supabase Auth, Postgres, Row Level Security, database functions, storage, and backend integrations
• Payment and settlement experiences, including UPI, payment providers, webhooks, transaction states, and reconciliation
• Debugging and improving existing product flows
• Secure handling of user, expense, and payment-related data
• Android and iOS testing, performance, and production releases
• Reviewing requirements and suggesting simpler or better solutions when appropriate

What we are looking for

• Strong production experience with React Native and TypeScript
• Hands-on experience with Supabase in a real application
• Experience implementing payment integrations or other transaction-sensitive workflows
• A solid understanding of authentication, database security, Row Level Security, and API design
• The ability to read an existing codebase and become productive quickly
• Strong debugging skills and attention to product behaviour and edge cases
• Clear communication and the confidence to suggest improvements instead of only following instructions

Product familiarity is required

We are a fast-moving team and expect candidates to arrive prepared. Before applying, install SplitSense, create your account, and spend some time using it as a real user. At minimum, create a group, add a few expenses, and explore the splitting methods, balances, settlements, group settings, and activity history.

We will ask detailed questions about features across the entire application during the interview. We want candidates who take the initiative to understand the product as real users before discussing how they would improve it as developers.

Question:

1. Have you implemented payments, UPI, webhooks, or transaction reconciliation in a production application? Briefly describe what you personally built and the most important edge case you handled.
2. What would you examine before adding or expanding payment capabilities in an expense-sharing application?
3. After creating a group, open its Group Settings. What are all four options shown under Default Split?
4. In Group Settings, what exact one-line explanation appears below Merge balances?
5. Did you notice anything that did not work well, felt unclear, or appeared to be a bug while exploring SplitSense? Briefly describe it. If you found nothing, write N/A.
