Job description
**About [](http://valka.ai/)**
Valka, a visionary spin-off from the Realms Group (the parent company of [](http://oddin.gg/)), is on a mission to **revolutionize the way people create and experience digital content**. Our team believes that content shouldn’t just be consumed; it should be **co-created in real time**, blurring the lines between imagination and reality. By harnessing the power of cutting-edge AI, we aim to build an **interactive human-digital platform** where virtual characters respond dynamically to each user’s voice, text, gestures, and more.
This is your chance to **join a diverse group of innovators** who are **driven to redefine what’s possible** in generative content. Together, we’re changing the paradigm from passive viewing to active participation, **unlocking new creative frontiers** across gaming, entertainment, education, and beyond.
