[PAID / COLLAB] Unreal Engine Developer – Large-Scale Immersive & Interactive Experience (Paris / Remote)

Hi everyone,

We’re launching LUMO XR, a new immersive platform blending real-time 3D, large-scale projection, interaction and narrative storytelling, powered by Unreal Engine.

The project sits at the crossroads of game engines, live experiences and location-based entertainment (LBE). We are creating a new format of immersive experience openning up virtual worls in the physical space.

We’re currently building a small R&D lab in Paris, working on early prototypes (mapping, audience tracking (with our partner Augmenta.tech), gameplay, guest behavior etc. )that will define the technical foundations of the platform.

The Project

  • Unreal Engine as the real-time core

  • Multi-surface / multi-camera rendering

  • Interactive systems (triggers, orbs, spatial interactions, tracking inputs)

  • Real-time synchronization between rendering, interaction and physical space

  • Strong focus on performance, scalability and clean architecture

This is a long-term project with serious backing (investor and France 2030 laureat), currently in a stealth / early development phase, so public information is intentionally limited.

Who We’re Looking For

An Unreal Engine Developer (or Tech Artist with strong UE skills) who:

  • Is comfortable working close to the engine

  • Enjoys prototyping systems, not just placing assets

  • Understands real-time constraints (latency, FPS, sync)

  • Is curious about pushing Unreal beyond “classic” use cases

  • Wants to help shape a new format from the ground up

You don’t need to be a AAA veteran, but you do need ambition, rigor, and curiosity.

Skills (not all mandatory)

  • Unreal Engine (Blueprints and/or C++)

  • Real-time rendering & optimization

  • Gameplay / interaction systems

  • Interest in projection, immersive setups, or physical installations is a big plus

Collaboration

  • Paid mission / contract, with possibility to evolve into a longer collaboration as we are looking for long term collaborators

  • Hybrid setup: Paris-based preferred, remote possible depending on profile

  • Small, focused team — high impact per person

Why Join?

  • You’ll work on something that doesn’t exist yet

  • Technical challenges that go beyond standard game pipelines

  • Real creative and technical ownership

  • A project aiming to redefine immersive entertainment, not just iterate on existing formats
