Bengaluru, Karnataka, India The IT Guy Full time ₹ 10,00,000 - ₹ 22,00,000 per year

About Us

At THE IT GUY, we craft intelligent, scalable systems that bridge hardware, AI, and software—powering next-generation products in streaming, IoT, and automation. Our projects range from AI-driven classification pipelines (Azure AI Foundry, OpenAI, vector search, ML models) to real-time signaling systems (NestJS, MQTT, WebRTC, RTMP) and SaaS dashboards with multi-tenant, role-based access control.

If you enjoy building systems end-to-end—from API design and data modeling to integrating AI models and optimizing inference pipelines—you'll love working with us.

Key Responsibilities

  • Backend Architecture & Development
  • Design and implement modular, scalable REST & GraphQL APIs using NestJS / / TypeScript.
  • Build and optimize database models using Prisma (PostgreSQL / MongoDB) with advanced query filtering, pagination, and role-based access.
  • Develop multi-tenant SaaS backend logic (JWT auth, refresh tokens, permissions, audit logs).
  • AI & Data Intelligence
  • Integrate and orchestrate LLMs and SLMs (Azure OpenAI, local models) for classification, enrichment, and reasoning.
  • Build agentic pipelines that chain ML classifier outputs with semantic reasoning and web-based enrichment layers.
  • Implement vector search, embeddings, and prompt-flow-based inference systems using Azure AI Search.
  • Work on model evaluation, feedback loops, and automated retraining or fine-tuning triggers.
  • Systems Integration
  • Develop and manage MQTT-based messaging systems for device communication and signaling.
  • Build WebRTC/RTMP streaming services for video/audio pipelines integrated with NodeMediaServer, Janus, or Asterisk.
  • Write automation scripts and microservices to handle real-time workflows and OTA updates for connected devices.
  • DevOps & Infra
  • Deploy services using Docker, PM2, or Jenkins pipelines on DigitalOcean / AWS / Azure.
  • Optimize APIs for scalability, security, and performance (rate limiting, caching, CSP headers, Brotli compression).
  • Manage secrets, environment configs, and CI/CD pipelines.

Preferred Skills

Core Backend:

  • NestJS / / Express
  • Prisma ORM / TypeORM
  • PostgreSQL / MongoDB
  • JWT, OAuth2, RBAC

AI Stack:

  • Azure AI Foundry, OpenAI SDK
  • Vector Search (Azure AI Search, Pinecone, or equivalent)
  • Model orchestration (PromptFlow, LangChain, or custom pipelines)
  • Familiarity with text classification, embeddings, and retrieval-augmented generation (RAG)

System & Infra:

  • MQTT / WebRTC / RTMP
  • Docker / Jenkins / Nginx
  • Cloud (Azure, AWS, DigitalOcean)
  • REST, WebSocket, and real-time architecture

Nice to Have

  • Experience with React / dashboards and integration of backend APIs.
  • Familiarity with IoT or hardware integrations (Raspberry Pi, camera/mic devices, relays, RF modules).
  • Understanding of data labeling pipelines, model evaluation, or ML Ops.
  • Exposure to Flutter / Electron apps interacting with backend APIs.

What We Offer

  • Exposure to cutting-edge AI + real-time systems.
  • Opportunity to work on products that integrate cloud, AI, and IoT seamlessly.
  • Collaborative and fast-moving culture with hands-on technical founders.
