ABOUT THE ROLE
We are looking for a Senior Software Engineer to design and implement a multi-tier sync architecture — from local device store through restaurant edge to cloud backend — for a high-volume QSR platform.
You will apply conflict-resolution strategies including vector clocks and merge policies, implement event sourcing, CQRS, and saga patterns across order, kitchen, payment, and receipt flows, and model the PostgreSQL cloud data layer against local and edge stores.
The role requires deep offline-first experience beyond simple caching, with a React Native and Node.js delivery stack.
WHAT YOU WILL DO
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
MUST HAVES
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 HAVES
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
PERKS AND BENEFITS
Professional growth: Mentorship, TechTalks, and personalized growth roadmaps
Competitive compensation: USD-based pay with education, fitness, and team activity budgets
Exciting projects: Modern solutions with Fortune 500 and top product companies
Flextime: Adaptable schedule with remote and office options
