Own an entire restaurant-analytics platform end-to-end — ship a database migration, a backend service, and a polished mobile screen in the same day.
Our client — a rapid-growing restaurant-analytics and consulting startup in Kolkata, founded by leaders from top e-commerce companies and premier institutes — is hiring a founding-calibre Senior Full-Stack Engineer. This is not a ticket-taker role that owns one layer and shrugs at the rest. You'll hold the whole platform in your head and be trusted with the entire product.

About the Role You will own the product end-to-end: a multi-service Node / Express + Sequelize backend on PostgreSQL, a Vite + React + TypeScript frontend (a Framework7 mobile-first customer app plus an admin console, packaged with Capacitor), a Gmail-OAuth data-ingestion pipeline that turns raw platform statements into a reconciled financial "gold" layer, authentication via Keycloak, and the billing, reporting,



and notification subsystems on top. You'll design schemas, write the queries, build the APIs, craft the UI, wire the deploys, and reason about the finance logic that makes the numbers correct to the rupee. You are expected to make architectural calls, not just implement them.

The AI-Augmented Edge Here, AI is your primary workforce. You'll use Claude Code, Cursor, and Gemini to scaffold services, write and refactor across the stack, generate tests, and reason about tricky data and finance logic — targeting a 3x-5x efficiency gain. You'll practise Cross-LLM Validation: one model writes, another reviews for correctness and edge cases. Your value is measured by working, correct, shipped product — features that reconcile, screens that delight, deploys that hold — not lines or tickets.

What You'll Do
Backend & Data: Design and build Node / Express services (customer, admin, user-center, ingestion,
