AI Engineer - Full Stack

Level: Confirmed to Senior, depending on project experience and technical autonomy
Team: Data & AI

An opportunity for experienced AI Engineers to build from Kolkata

Are you an experienced AI Engineer / Full Stack AI Engineer looking for an opportunity to work on Generative AI, LLMs, RAG, AI Agents and production-grade AI applications?

This is an exciting opportunity for experienced technology professionals who want to build, deploy and industrialize real-world AI solutions while working with an international team.

We are specifically looking for professionals who are open to working from Kolkata.

If you have moved away from Kolkata for technology opportunities and are now looking for a role where you can return to Kolkata without compromising on the quality or scale of your work, this could be an excellent opportunity.

Salary is not a constraint for the right candidate. We are open to competitive compensation based on relevant experience, technical depth and project expertise.

About the Role

The Data & AI team is looking for a Full Stack AI Engineer who can contribute across the complete AI engineering lifecycle from prototype and architecture through development, deployment, monitoring and continuous improvement.

You will work on solutions involving:
