Company

hirify.global builds a platform for validating autonomous vehicles, robots, and other Physical AI systems in high-fidelity virtual environments.

What you will do

• Own the migration of a Windows-based renderer to production-quality Linux on Nvidia graphics using Vulkan.
• Diagnose and resolve differences between DirectX and Vulkan backends, including memory usage, shader compilation, driver behavior, synchronization, and rendering artifacts.
• Build comparison harnesses and regression tests to verify equivalent output across platforms and supported camera, lidar, and radar configurations.
• Establish GPU and CPU profiling workflows on Linux, identify bottlenecks, and optimize rendering performance.
• Contribute to wide-angle and multi-view rendering, Gaussian splatting, lighting, and GPU computation initiatives.
• Partner with build, infrastructure, and simulation engineers across containerized applications, build systems, and cloud GPU instances.

Requirements

• 7+ years of experience in real-time graphics or engine programming, including shipping at least one product.
• Production experience writing and debugging Vulkan render paths, including memory allocation, descriptor management, synchronization, and validation layers.
• Production Linux graphics experience with GPU drivers, Mesa or vendor stacks, shader toolchains, compositors, containers, and debugging tools.
• Strong modern C++ skills in a large codebase with a serious build system and CI.
• Experience profiling and optimizing GPU and CPU performance with tools such as RenderDoc, Nsight, or equivalents.
• Ability to independently scope and deliver complex graphics work and communicate technical trade-offs clearly.

Nice to have

• Experience shipping Unreal Engine 5.5+ on Linux with the Vulkan RHI and familiarity with Unreal rendering internals.
• Meaningful contributions to Vulkan-related open source projects such as Mesa, DXVK/VKD3D, Proton, SPIR-V tooling, or validation layers.
• Experience porting renderers between DirectX 11/12 and Vulkan.
• Background in video streaming, cloud gaming, remote rendering, sensor simulation, physically based rendering, neural rendering, or Gaussian splatting.

Culture & Benefits

• Collaborative culture focused on building and scaling simulation technology.
• Equity and employer-paid supplemental medical, mental health, dental, and vision benefits.
• Flexible paid vacation, sick time, winter shutdown, and 11+ holidays annually.
• Paid parental leave and an equipment budget.
• Annual learning and development stipend.
