About The Position

Engenious is a technology company building next-generation AI products that transform how people work, learn, and create. We partner with fast-growing startups and global companies to design and scale intelligent systems — from AI-powered applications to full-stack platforms used by millions. Our team combines deep engineering expertise with product thinking to deliver solutions that are not just technically strong, but genuinely useful.

We’re looking for a Full-Stack Engineer to join our team and work on AI-driven products in the education space.
In this role, you will be working as part of an Engenious team embedded with one of our clients, a leading technology company building products used at global scale. You’ll collaborate closely with both Engenious and client-side teams to deliver high-impact solutions.

This role combines full-stack engineering with practical application of modern AI technologies, and you’ll be expected to actively work with AI-powered features as part of your day-to-day development.
