Role Overview

We are seeking a Software Engineer III to build and maintain OpenXR-based XR applications. This onsite role in Redmond involves working closely with engineers and cross-functional partners to prototype, implement, and iterate immersive experiences that run across OpenXR-capable runtimes and devices.

This is a structured, full-time contingent role — not freelance or project-based.

Key Responsibilities

• Develop XR applications using OpenXR (architecture, implementation, testing, iteration)
• Build interactive XR features including:
• Input handling (controllers, hands, action sets, haptics)
• Scene and interaction systems (grabbing, ray interactions, 3D UI)
• Rendering and performance optimization (frame pacing, latency-sensitive updates)
• Integrate platform/runtime capabilities such as tracking spaces, anchor systems, passthrough, and scene understanding via OpenXR extensions
• Write clean, testable code and contribute to CI/build scripting
• Debug runtime/device issues (graphics, tracking, input) and provide reproducible fixes
• Collaborate with product, UX, and engineering stakeholders
• Document technical designs, tradeoffs, and implementation decisions

Required Qualifications

• 3+ years of professional software development experience
• Experience shipping real-time 3D applications (XR, gaming, simulation, or visualization)
• Practical OpenXR experience (instance/session lifecycle, swapchains, spaces, actions)
• Strong C/C++ and/or C# expertise
• Experience with one of the following:
• Unity (C#) with OpenXR plugin ecosystem
• Unreal Engine (C++) XR pipeline
• Custom/native OpenXR rendering using Vulkan, OpenGL, or DirectX
