Summary: Seeking a Senior Software Engineer to lead offline-first data synchronization for a global QSR POS platform, designing multi-tier sync with CRDT-based frameworks and event-driven architectures. Highlights: 1. Design multi-tier synchronization for global QSR POS platform 2. Implement conflict-resolution with CRDT-based frameworks 3. Apply event sourcing, CQRS, and saga patterns **About the role** We are looking for 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\-based frameworks including 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. The role requires hands\-on CRDT sync experience, React Native, Node.js, and distributed\-systems fundamentals. **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 using CRDT\-based sync frameworks such as Automerge or Ditto, along with vector clocks, last\-write\-wins, merge policies, and eventual consistency; * 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. **Must haves** * **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 beyond simple caching, including hands\-on experience with **Automerge**, **Ditto**, or comparable CRDT\-based synchronization frameworks; * Solid understanding of 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** or **GitHub Copilot**; * Upper\-intermediate English level. **Nice to haves** * Experience with local\-first synchronization engines such as **ElectricSQL**; * Experience with mobile local persistence technologies such as **SQLite**, **MMKV**, or **WatermelonDB**; * Experience with **PostgreSQL JSONB** or document modeling; * Experience in the QSR, retail, or other high\-volume transactional environments. **Perks and benefits** * **Professional growth:** Accelerate your professional journey with mentorship, TechTalks, and personalized growth roadmaps. * **Competitive compensation:** We match your ever\-growing skills, talent, and contributions with competitive USD\-based compensation and budgets for education, fitness, and team activities. * **A selection of exciting projects:** Join projects with modern solutions development and top\-tier clients that include Fortune 500 enterprises and leading product brands. * **Flextime:** Tailor your schedule for an optimal work\-life balance, by having the options of working from home and going to the office, whatever makes you the happiest and most productive.
