Sr. Software Engineer, Model Scaling, AI Infrastructure

We are looking for strong software engineers to help
scale the next generation of large AI models for Autopilot, Optimus &
Digital Optimus. This role sits at the intersection of distributed systems,
machine learning, and performance engineering. You will work closely with ML
practitioners and infrastructure engineers to improve training efficiency,
accelerate experimentation, and enable larger and more capable models.

The ideal candidate is excited about both systems and
machine learning. You should be comfortable debugging distributed training
issues, analyzing model behavior, and using data to demonstrate how
infrastructure improvements translate into better model quality.

You will help build and optimize large-scale training
systems running on thousands of GPUs while developing the tools, metrics, and
workflows needed to make model scaling faster and more predictable.

• Optimize large-scale distributed training across
  thousands of GPUs
• Improve training throughput, utilization, reliability,
  and scalability
• Develop tooling to identify bottlenecks in compute,
  networking, memory, and data pipelines
• Design and implement performance optimizations across
  PyTorch, CUDA, communication libraries, and training frameworks
• Partner with researchers to evaluate how infrastructure
  changes impact model quality, convergence, and downstream metrics
• Analyze training runs and build dashboards that connect
  system performance to model outcomes
• Drive improvements in model scaling efficiency, including
  larger models, longer context lengths, and higher-quality datasets
• Debug complex issues across software, hardware,
  networking, and machine learning systems
• Build infrastructure that accelerates experimentation and
  shortens iteration cycles for researchers

• Strong software engineering fundamentals in Python and
  C++
• Experience with distributed systems, high-performance
  computing, or large-scale infrastructure
• Understanding of machine learning fundamentals, including
  optimization, training dynamics, and evaluation
• Familiarity with PyTorch and modern deep learning
  frameworks
• Ability to analyze performance bottlenecks using
  profiling and observability tools
• Strong debugging and problem-solving skills
• Excellent communication and collaboration skills
