nDreams is a world-leading virtual reality game developer and publisher, combining innovation with excellence. Our projects are a leap forward for VR and for the studio and we are looking for talented people to help turn them into a reality.
We’re the studio behind the #1 Selling, Best of E3 Award-winning, Phantom: Covert Ops and we’ve got several exciting projects planned for 2021 and beyond, including Fracked, our recently announced PS VR exclusive. Once you’ve seen what we’re up to, we’re convinced you’ll want to be involved…
Our artists believe in the power of VR to immerse and entertain players like no other medium can. We are seeking a Principal Technical Artist to collaborate with and support the team, ensuring their content looks great in-game whilst adhering to the technical constraints of projects and hardware. Whether you are a games industry veteran or an experienced VFX Technical Artist/Director who’d like to make a change, we’d love to hear from you.
