XR Software Engineer, Platform

Rivet Industries•Bellevue, WA

About The Position

Build real-time spatial UIs across AR, VR, and MR on our embedded Linux and Android devices. The stack is primarily C# in Unity or StereoKit, OpenXR underneath for cross-runtime portability. You'll ship XR features that integrate with device services, peripherals, and backend APIs. Some of what you build becomes part of a shared spatial SDK that other Rivet programs depend on.

Requirements

5+ years building XR, real-time 3D, or spatial computing applications, with features that shipped to production.
BS in CS, CE, or a related field, or equivalent demonstrated experience.
Proficient in C#. Shipped features in Unity or StereoKit.
Working knowledge of OpenXR and at least one XR runtime (HoloLens, Quest, Magic Leap, ARCore).
6DOF and spatial input fundamentals.
3D math: vectors, matrices, quaternions, transforms.
Real-time 3D graphics pipeline: draw calls, shaders, render targets, GPU state.
Android or embedded Linux experience.
Production performance work: profiling, CPU/GPU/memory tradeoffs.

Nice To Haves

C++ at the NDK or vendor-SDK level (camera, sensor, platform).
Java or Kotlin for Android companion apps.
Python for scripts, tooling, or test pipelines.
Computer vision or perception work, classical CV through ML pipelines, applied to AR or spatial computing.
Unreal Engine, or another 3D engine besides Unity.
Written your own shaders (HLSL, GLSL, Shader Graph).

Responsibilities

Build XR interfaces in Unity or StereoKit for AR, VR, and MR.
Write the C# behind real-time UI, rendering, and interaction.
Integrate with OpenXR and platform XR runtimes.
Profile and tune rendering and input latency on device.
Work with the content team on asset pipeline and on-device optimization.
Build companion apps for Android devices, or wire up peripheral hardware (sensors, Bluetooth tools).
Write native C++ for performance-critical paths or platform integration.
Build real-time media capture and streaming pipelines.
Write Python for test harnesses, scripts, or CI tooling.
Work with backend (ASP.NET / .NET), firmware, and design on features that span device and server.
