Location: Hybrid in San Francisco, CA or Toronto, ON, with remote work available in the US and Canada

Company

hirify.global develops hirify.global World, a multi-sensor simulator for autonomous driving research and development.

What you will do

• Take neural and generative models from research code and checkpoints to versioned, reproducible, exportable production artifacts.
• Optimize diffusion, flow-matching, scene reconstruction, and vision foundation models for latency and memory efficiency.
• Profile model graphs, GPU kernels, memory movement, and host-device synchronization using CUDA and GPU performance tools.
• Build benchmarks and numerical-parity tests that protect simulation realism and downstream autonomy metrics.
• Design shared export, versioning, model registry, and build tooling for the sensor simulation team.
• Collaborate with research scientists to make new architectures exportable, efficient, and hardware-friendly.

Requirements

• Experience developing and shipping production-quality software and ML systems at scale.
• Hands-on experience optimizing and deploying models with TensorRT, torch.compile, torch.export, ONNX, quantization, or pruning.
• Experience handling custom CUDA operators and operations that do not export cleanly.
• Ability to profile GPU workloads with Nsight Systems, Nsight Compute, or the PyTorch profiler, and write or modify CUDA or Triton kernels.
• Strong understanding of vision transformers, diffusion and flow-matching models, and vision foundation models.
• Experience launching and debugging GPU workloads in AWS, GCP, or equivalent cloud infrastructure, including containers, orchestration, and CUDA/PyTorch/TensorRT compatibility.

Culture & Benefits

• Competitive compensation and equity awards.
• Medical, dental, and vision coverage for full-time employees.
• Unlimited vacation, flexible hours, and work-from-home support.
• Daily drinks, snacks, and catered meals when working in the office.
• Regular team-building activities and social events held on-site, off-site, and virtually.
