About MeshMap
MeshMap helps XR creators and developers build location-based AR and VR apps with an open 3D map, a Unity SDK, and APIs. Users can publish place-based games and tours, contribute scans to expand coverage, and integrate mapping data in apps. The platform supports creation, distribution, and discovery of immersive content across devices.
Skills
About the Role
You'll own the core technical systems behind MeshMap's real-time immersive experiences. You'll move fluidly between high-level architecture and low-level debugging, working across Unity development, graphics optimization, networking, device performance, and deployment pipelines, especially when dealing with constrained hardware, headset runtimes, multiplayer systems, and live venue environments. You'll partner closely with design, art, product, and operations teams to make sure every experience is technically stable and genuinely fun to use, while helping shape engineering standards as the company grows.
Requirements
- 8+ years of professional experience in games, XR, real-time 3D, simulation, or engine development
- Strong Unity and C# experience
- Experience shipping or maintaining real-time applications on constrained hardware
- Deep understanding of performance profiling and optimization for mobile, VR, AR, or MR
- Strong understanding of graphics engineering, rendering performance, shaders, GPU profiling, memory budgets, and frame timing
- Experience with multiplayer or networked real-time systems
- Ability to reason clearly about network topology, authority models, synchronization, latency, and transport behavior
- Comfortable debugging on physical devices, not just in-editor
- Strong ownership mindset and ability to make practical technical decisions in a fast-moving environment
- Comfortable in an early-stage, evolving company environment
- Comfortable leading projects and making independent decisions
- Must be eligible to work in the U.S.
Responsibilities
- Build and maintain real-time Unity systems for AR, VR, MR, and location-based gameplay
