About the Company

TQAY is the technology arm of RASTEC Group. We deliver secure, scalable software and automation for Qatar & GCC enterprises: AI solutions, custom SaaS, ERP/IMS/EMS modules, omni-chat, API integrations, data platforms, and cloud/DevOps.

About the Role

Own end-to-end delivery of n8n automations, Meta App integrations (WhatsApp/IG/FB to Live), and full-stack features (Next.js + Node/TS + PostgreSQL/Supabase w/ RLS). Additionally, lead two project capabilities:

• QR-based Asset Tagging & Tracking (generation, printing, scanning, lifecycle)
• Bill of Materials (BoM) generation & governance (imports, change control, ERP/SAP sync)

Responsibilities

• Automations & AI: Build n8n workflows (HTTP triggers, queues, retries/DLQ, circuit breakers) for omni-chat, lead/ticket routing, alerts, analytics. Wire LLM pipelines (function calling/tools, RAG w/ pgvector) with cost/perf monitoring.
• Meta App Integrations: Take Meta Apps to Live: App Review packs, permissions (whatsapp_business_messaging, pages_messaging), reviewer test steps, webhooks (subscribe/verify), rate-limit/backoff, Data Use Checkup.
• QR Asset Tagging (Furniture/Equipment): Design data model for assets, locations, custodians, status, maintenance history. Implement QR/Barcode generation & printing: QR (Model 2), Code128/EAN-13 where needed; label templates (ZPL/EPL/PDF), thermal printers (Zebra/Brother), PrintNode/Cloud Print. Build scan apps (PWA/mobile-web or light native): camera scanning with ZXing/ML Kit, offline cache & sync on reconnect, GPS/timestamp, role-based actions (assign/transfer/audit). Bulk ops: CSV/XLSX import/export, duplicate detection, audit logs, asset lifecycle (commission → in-use → repair → retire). Dashboards: counts by site/department, utilization, movement trails; webhooks to notify on exceptions.
• BoM Generation & Governance: Model BoM entities (assembly, sub-assembly, component), versions, alternates, UoM, cost roll-ups. Build imports from CSV/XLSX (and SAP extracts), validation rules, conflict resolution, and approval workflow (draft → review → released). Expose APIs for ERP/CMMS sync; support change control (ECO/ECN) and full history/audit. Optional: SAP/Oracle integration patterns (material master fields, BoM sync jobs) via n8n connectors/custom nodes.
• Full-Stack Delivery & Platform: Back end: TypeScript/Node.js (Express/Fastify), Prisma/Drizzle, OpenAPI contracts, structured logs. Front end: Next.js 14/15 (App Router), SSR/ISR, server actions, Tailwind + shadcn/ui, forms/uploads, i18n (EN/AR). Data: PostgreSQL/Supabase schemas, migrations, RLS, indexes; Redis/queues for background jobs. Security/Observability: OAuth/OIDC, JWT, request signing & replay protection, Sentry/Prom/Grafana (or equiv), CI/CD (GitHub Actions), Docker.
