# About Cybernetyx:

Have you ever wondered why computing experiences are still limited to specific devices such as Desktops, Laptops and Cell phones? Why the walls, tables or whiteboards around us do not function as computers which blend in our environments and we can interact with them seamlessly via touch and gestures?

Imagine a technology which can turn any flat surface in the world around you such as a wall, a whiteboard or a piece of furniture into a touch surface. Now further picture if this can be achieved with a sensor by just scanning at the surface from a distance - without adding any electronics in the surface itself?

Cybernetyx (www.cybernetyx.com) is a Germany-based multinational technology group focused on human-machine interface solutions. Cybernetyx is the World's No. 1 OEM/ODM technology developer and market leader in Interactive Projection industry via its industry-leading EyeRISTM interactive vision systems.

EyeRISTM technology powers millions of interactive projection and display solutions including the products of NEC Display, ViewSonic Corporation, SONY, Delta, TATA Interactive and IL&FS.

World's top display manufacturing companies today are licensing and integrating the ground-breaking EyeRISTM computer vision interactive technology into their products - and transforming how humans have interacted with their computers and displays like never before. We are building the future of all human-machine interaction - much beyond the limitations of the keyboard, mouse or the tiny touchscreens on our cellphones.

Job Description:

We need a programmer who works on full-stack- MEAN, has sound knowledge of working with NodeJS for both backend and frontend development, to develop web application for one of our industry leading Ed-Tech Brand.

This is a full-time, permanent position, and you You- ll become part of an agile, multidisciplinary team. You get a scrum master to help guide the process. We foster developer empowerment and keep management layers and meetings to a minimum. We believe in experimentation over lengthy discussions.

# WHO SHOULD APPLY:

- You thrive on the cutting edge of technology and get excited to learn more, push boundaries and innovate every day. The tech start-up industry is where you think all the action is and where you want to be.
