Principal XR Game Engineer

About GLO

GLO is reimagining sightseeing for the age of immersive tech. We create interactive gaming tours that transform real city streets into playful, story-rich experiences using cutting-edge augmented reality (AR) technology. Our tours are social, creative, and designed to make people feel like they’ve stepped inside the city rather than just walked through it.

We’re building something new at the intersection of entertainment, culture, and technology, and we’re looking for someone who can capture that energy and turn it into content that drives real attention.

The Role

As a Principal XR Game Engineer, you’ll own core technical systems for MeshMap’s real-time immersive experiences. You’ll work across Unity development, graphics optimization, networking, device performance, and deployment pipelines.

This role is ideal for someone who can move between high-level architecture and low-level debugging, especially when working with constrained hardware, headset runtimes, multiplayer systems, and live venue environments.

Key Responsibilities

• Build and maintain real-time Unity systems for AR, VR, MR, and location-based gameplay
• Own technical architecture for interactive experiences across mobile and XR hardware
• Profile and optimize performance on target devices, including CPU, GPU, memory, thermal load, and frame pacing
• Diagnose and resolve rendering bottlenecks related to shaders, draw calls, overdraw, batching, LODs, textures, lighting, and post-processing
• Design and implement networking systems for multi-user immersive experiences, including authority, replication, synchronization, latency, and bandwidth management
• Debug device, connectivity, build, and runtime issues across headset and mobile platforms
• Improve Unity tooling, build profiles, asset workflows, and deployment reliability
• Work closely with design, art, product, and operations to ensure experiences are technically stable and fun to use
