Java Backend Developer (Middle+/Senior)
About the company
At Gracia, we are proud to be the first in the world to create photorealistic volumetric videos based on Gaussian Splatting / 4DGS. For the past 2.5 years, we have been building the infrastructure for producing and distributing this new type of content.
4DGS is a new content format where a video can be rendered from any point in space inside it. This is not our first startup: we are building Gracia with an experienced team of ex-Prisma AI people — 150M App Store downloads, #1 AI avatars in 2022 — and ex-netmonet people — exit in 2021, with a valuation of several billion rubles. We are building this company for ourselves: designing it to become a real, full-scale business for real users, not just something to be sold to Big Tech.
How does it work?
- A scene is captured simultaneously from multiple angles using regular cameras.
- The synchronized camera videos are converted by our technology and pipeline into a photorealistic, dynamic 3D scene.
- This scene is then rendered in real time on a device, allowing the user to watch the video from any point in space at any moment in time — in other words, to walk inside the video, with the image recalculated instantly and without latency. Passthrough / mixed reality mode also allows the user to blend volumetric video with their own environment, effectively bringing a real captured scene into their own space.
This is not 3D animation or an avatar — it is real footage, a new type of content and user experience. Over the past three years, the technology has already proven that it will fundamentally change not only what VR/AR content looks like, but also how virtual production for films works, as well as how immersive replays will be produced for sports broadcasting.
Who needs this? We are already working with leading Big Tech companies, Hollywood productions using our technology for films, fashion brands, and production companies in broadcasting — we can share more during the interview. We are already receiving more data than we can process.
Our target industries:
- XR education: medical, fitness, blue-collar training
- Sports broadcasting
- Virtual production
- XR entertainment: music videos, concerts, fashion
What we have achieved in 2.5 years:
- We were the first in the world to launch real-time rendering of 4DGS content on low-end GPU standalone devices: Quest 3/3S + Pico 4U, Apple Vision Pro, iPhone, Android
- Proved PMF — product-market fit with paying users
- Confidently crossed $2M ARR
- Raised $3.5M from international funds
- Built a partner network of volumetric capturing studios in the US, UK, Europe, Canada, and Japan
- Grown to a team of 30 people
