Job#: 3030492 Job Description: Software Engineer III
Location: Redmond, Washington (On-site)
Employment Type: Contract
Role Overview
We are seeking an OpenXR App Developer to assist in building and maintaining OpenXR-based XR applications. This role involves close collaboration with engineers and cross-functional partners to prototype, implement, and iterate on immersive experiences that run across OpenXR-capable runtimes and devices.
Key Responsibilities
- Develop XR applications using OpenXR, covering architecture, implementation, testing, and iteration.
- Build interactive features including input handling (controllers, hands, action sets, haptics) and scene/interaction systems (grabbing, ray interactions, UI in 3D).
- Implement rendering and performance optimizations, focusing on frame pacing and latency-sensitive updates.
- Integrate platform and runtime features where applicable, such as tracking spaces and passthrough.
- Create clean, testable code and contribute to CI/build scripts.
- Debug runtime and device issues related to graphics, tracking, and input, providing clear reproduction steps and fixes.
- Collaborate with product, UX, and engineering stakeholders, documenting designs and trade-offs.
Required Qualifications
Experience: A minimum of 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 like instance/session, swapchains, spaces, and actions.
Technical Skills: Strong skills in C/C++ and/or C# with solid debugging capabilities. Experience with a real-time engine or framework such as Unity (C#) with the OpenXR plugin ecosystem, Unreal (C++) XR pipeline, or custom/native OpenXR rendering with Vulkan/OpenGL/DirectX. An understanding of rendering and performance constraints for XR (e.g., 72/90/120 FPS targets, GPU/CPU bottlenecks, latency) is required.
Preferred Qualifications
- Experience having shipped at least one OpenXR-based application or feature to production.
- Familiarity with OpenXR extensions (e.g., hand tracking, eye gaze, foveated rendering, scene/space-related extensions).
- Graphics experience with Vulkan, OpenGL, or DirectX, including shaders and profiling tools like RenderDoc.
- Android XR experience (Gradle, NDK, JNI) or low-level platform integration.
- Experience building reusable components or frameworks for XR interaction or application scaffolding.
Compensation & Benefits
Compensation for this role is set at $75 per hour.
We are an equal opportunity employer and welcome applications from all qualified candidates regardless of race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
