Software Engineer III - OpenXR Developer

About this role

We are seeking a Software Engineer III to join an onsite team in Redmond, focused on building and maintaining OpenXR-based XR applications. In this role, you will collaborate closely with engineers and cross-functional partners to prototype, implement, and iterate on immersive experiences that run across OpenXR-capable runtimes and devices.


Responsibilities

• Develop XR applications using OpenXR, covering architecture, implementation, testing, and iteration.
• Build interactive features including:
• Input handling (controllers, hands, action sets, haptics)
• Scene and interaction systems (grabbing, ray interactions, UI in 3D)
• Rendering and performance optimizations (frame pacing, latency-sensitive updates)
• Integrate platform/runtime features where applicable (tracking spaces, anchor-like constructs, passthrough/scene understanding via extensions).
• Create clean, testable code and contribute to basic CI/build scripts as needed.
• Debug runtime and device issues related to graphics, tracking, and input, providing clear reproduction steps and fixes.
• Collaborate with product, UX, and engineering stakeholders; document designs and tradeoffs.

Qualifications

• Minimum Qualifications:
• 3+ years of professional software development experience (or equivalent).
• Hands-on experience shipping 3D real-time applications (XR, games, simulation, or visualization).
• Practical experience with OpenXR core concepts such as instance/session, swapchains, spaces, and actions.
• Strong skills in C/C++ and/or C#, along with solid debugging abilities.
• Experience with a real-time engine or framework such as:

• Unity (C#) and OpenXR plugin ecosystem, or
• Unreal (C++) XR pipeline, or
• Custom/native OpenXR rendering with Vulkan/OpenGL/DirectX.

• Understanding of rendering and performance constraints for XR (72/90/120 FPS targets, GPU/CPU bottlenecks, latency).
• Preferred Qualifications:
• Experience shipping at least one OpenXR-based app or feature to produ...
