Descripción de la vacante

AgileEngine is seeking a Senior Software Engineer to own offline-first data synchronization for a global QSR POS platform, designing multi-tier sync across device, restaurant edge, and cloud backend.

You will implement conflict-resolution using CRDT frameworks such as Automerge or Ditto, apply event sourcing, CQRS, and saga patterns across order and payment flows, and model the PostgreSQL cloud data layer against local and edge stores.

Formación

• 4+ years of software engineering experience with production distributed-data or synchronization systems.
• Strong experience with React Native, TypeScript, and Node.js.
• Experience with offline-first or local-first data architectures and CRDT-based synchronization frameworks (Automerge, Ditto).
• Understanding of distributed systems fundamentals: conflict resolution, eventual consistency, idempotency, 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 or GitHub Copilot.
• Upper-intermediate English level.

Responsabilidades

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