About Brainy Neurals

Brainy Neurals is a founder-led AI engineering company based in Ahmedabad. For nine years we have shipped production AI across computer vision, document intelligence, generative AI and AI agents, and we are ISO 27001 certified and a member of NVIDIA Inception.

Our AI engineers build the models and the pipelines behind them. As our Senior MERN Stack Developer, you will own the web applications that bring their work to real users, from the first commit to production.

What you will do

• Build complete web applications on React, Node.js, Express and MongoDB, covering frontend, backend, database and deployment.
• Project management for every MERN app you work on is yours, from breaking requirements into tasks and estimating timelines through code reviews and releases.




• You will develop REST APIs and integrate the third-party services each app needs.
• Alongside our AI developers, you will connect their models and AI services to the app, wiring up LLM calls, streaming responses, file uploads and background jobs.
• Speed is part of the job, so you will tune bundle size, lazy loading, caching, database queries and server memory until pages load fast under real traffic.

What you need

• You have at least 3 years of full-time experience building MERN applications, and internships do not count toward them. Within those years, you have personally built enterprise SaaS apps and kept them scalable, reliable, robust and quick to respond as usage grew.
• Your React, Node.js, Express and MongoDB skills are strong enough to take an app from an empty repository to production on your own. That includes building JWT authentication yourself, with refresh tokens and role-based access control.
