About the Position

We are seeking a Senior Software Engineer with 4+ years of experience in distributed-data or synchronization work to join our team in Argentina, Brazil, Colombia, or Mexico. You will design and implement a multi-tier sync architecture - from local device store through restaurant edge to cloud backend - for a high-volume QSR platform.

Responsibilities

Design multi-tier synchronization across local device storage, restaurant edge, and cloud backend with offline-first guarantees;
Implement conflict-resolution strategies, including vector clocks, last-write-wins, merge policies, and eventual consistency;
Apply event sourcing, CQRS, and saga patterns for order, kitchen, payment, and receipt flows;
Use real-time pub/sub or WebSockets to maintain live state across devices;
Model the cloud data layer on PostgreSQL and define reconciliation between local, edge, and cloud data stores.

Requirements

4+ years of software engineering experience with production distributed-data or synchronization work;
Strong React Native, TypeScript, and Node.js;
Experience with offline-first or local-first data beyond simple caching;
Solid distributed systems fundamentals, including conflict resolution, eventual consistency, idempotency, and ordering;
Experience with event-driven architectures and asynchronous messaging;
Experience with PostgreSQL and relational data modeling;
Experience using AI-assisted development tools such as Claude and GitHub Copilot;
Upper-intermediate English level.

Nice to Have

Experience with CRDT-based synchronization, such as AutoMerge or Yjs;
Experience with a local-first synchronization engine such as ElectricSQL;
Experience with mobile local persistence technologies such as SQLite, MMKV, or WatermelonDB;
Experience with PostgreSQL JSONB or document modeling;
QSR, retail, or high-volume transactional experience.
