Job Description:

We’re looking for a Contingent Worker (CW) to help build and maintain OpenXR-based XR applications. You’ll work closely with engineers and cross-functional partners to prototype, implement, and iterate on immersive experiences that run across OpenXR-capable runtimes/devices.

Job Responsibility:

  • Develop XR applications using OpenXR (end-to-end: architecture, implementation, testing, and iteration)
  • Build interactive features such as: Input handling (controllers, hands, action sets, haptics) Scene/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 if available via extensions)
  • Create clean, testable code and contribute to basic CI/build scripts as needed
  • Debug runtime/device issues (graphics, tracking, input) and provide clear repro steps and fixes
  • Collaborate with product/UX and engineering stakeholders
  • document designs and tradeoffs

Requirements:

  • 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: instance/session, swapchains, spaces, actions)
  • Strong C/C++ and/or C# skills (depending on stack), plus solid debugging skills
  • 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/perf constraints for XR (72/90/120 FPS targets, GPU/CPU bottlenecks, latency)

Nice to have:

  • Shipped at least one OpenXR-based app or feature to production
  • Experience with OpenXR extensions (e.g., hand tracking, eye gaze, foveated rendering, scene/space-related extensions)
  • Graphics experience: Vulkan/OpenGL/DirectX, shaders, profiling tools (RenderDoc, engine profilers)
  • Android XR experience (Gradle, NDK, JNI) or low-level platform integration
  • Experience building reusable components/frameworks for XR interaction or app scaffolding
What we offer:
  • medical, dental, vision, life, disability, and other insurance plans
  • ESPP (employee stock purchase program)
  • 401K program with company match after 12 months
  • HSA (Health Savings Account on the HDHP plan)
  • SupportLinc Employee Assistance Program (EAP) with up to 8 free counseling sessions
  • corporate discount savings program
  • on-demand training program
  • access to certification prep and a library of technical and leadership courses/books/seminars after 6+ months
