Full-Stack AI & Backend Engineer (Mobile + Generative AI)

About the Project

We are launching Onevio, an ultra-premium, luxury-branded automated platform operating on dual tracks. The B2B track for merchants automates marketing, invoicing, and cross-channel social media posting via voice/text commands over WhatsApp. The B2C track for individuals automates document parsing, smart folder organization, and proactive chronological reminders.

We are seeking a highly skilled, hands-on engineer to build our core platform architecture, integrate multimodal AI systems, and deploy a seamless cross-platform mobile application.

• Core Responsibilities

AI Integration & Orchestration: Design and optimize autonomous pipelines using Google Gemini 1.5 Pro/Flash (via Vertex AI) for zero-shot document layout parsing, metadata extraction, and dynamic JSON schema mapping.

• Backend & Automation Pipelines: Develop a distributed microservices backend to handle real-time Meta Cloud Webhooks (WhatsApp integration), automated SMTP relays, and multi-channel social media publishing APIs (Instagram, Facebook, Google Business Profile).

• Database Architecture: Build and manage a highly secure Multi-Tenant PostgreSQL database ensuring absolute structural separation between corporate client spaces and personal user profiles.

• Mobile Development: Implement a clean, high-performance cross-platform application natively using Flutter or React Native, adhering strictly to minimal luxury visual aesthetics (Light/Dark mode hardcoded).

• Guardrails & Queue Management: Build active background worker queues (Redis + BullMQ/RabbitMQ) to process large file/voice ingestion feeds and deploy real-time validation guardrails to prevent data routing mismatches.
