Project Essentials

Cloudinary is a platform that delivers media at scale. It is an incredibly feature-rich system offering solutions for both developers and content producers, marketers, graphic designers and media managers. Besides storage and delivery, Cloudinary offers rich image and video transformations with object recognition, smart processing, automatic analysis and large scale media management. With 5000 new images and videos generated every second, we are looking for new developers to join our rapidly growing team working as an integrated part of the R&D department.

The Kraków Team is responsible for both frontend and backend side development of critical Cloudinary products (eg. the completely new product, Digital Asset Management solution and others) with full ownership over the architecture, technology, development and the process.

“The most amazing part of working for Cloudinary is the company culture. We feel like members of the family, we are cared for, our voice is heard and we love to work with every team member. Trust me, even though it sounds weird. Come see us ;)” - one of the team members.
