About the client

Our client is not just building a software, they are designing meaningful, intelligent systems that connect people and AI in powerful new ways. Whether it's powering chat-based AI companions, smart real-time dashboards, or backends that scale across zones and users, they believe in ownership, honesty, and bias for action.

The Role

As a Fullstack Engineer, you'll work across their backend and frontend systems to build scalable, reliable, and delightful features. From designing APIs in Python or Node.js, to crafting user experiences in React.js, your work will be critical in shaping core platforms and AI-first experiences.

You'll collaborate directly with product, AI, and design teams to ship real impact fast.

Responsibilities

• Design and implement backend services in Python (FastAPI, Flask) or Node.js (Express, NestJS)
• Build and maintain frontend features using React.js, Next.js, and Tailwind CSS
• Develop APIs that support AI agents, user sessions, and real-time data sync
• Work with databases (PostgreSQL, Supabase, Redis) to build flexible and scalable data models
• Write clean, testable, and well-documented code
• Collaborate closely with AI engineers to integrate LLMs, vector DBs, and inference pipelines
• Deploy apps using modern DevOps stacks (Vercel, Docker, Cloudflare, Supabase, etc.)
• Own features end-to-end: from specs and implementation to testing and monitoring

• Used Supabase or Firebase in production
• Built internal tools, dashboards, or SaaS platforms
• Background in building systems for authentication, billing, or user management
