Job Description

Member of Technical Staff, Research Engineer – GPU Performance

Runway

• Help world models train faster and run more efficiently. • Profile, optimize, and rearchitect systems that turn research ideas into models that run at scale and in real time. • Optimize training throughput across large GPU clusters. • Design and maintain distributed training infrastructure. • Profile and accelerate inference pipelines for real-time multimodal generation. • Optimize and scale training infrastructure to improve efficiency and reliability. • Contribute to the entire stack, from low-level kernel optimizations to high-level model design.

Job Requirements

  • 4+ years of experience in systems engineering, ML infrastructure, or performance optimization for deep learning.
  • Familiarity with GPU kernel development (CUDA, Triton, CUTLASS) and distributed systems (NCCL, collective communication, model parallelism).
  • Experience with ML framework internals (PyTorch, JAX) and mixed-precision / low-precision techniques (FP8, INT8).
  • Experience building and operating large-scale training infrastructure, including fault tolerance and cluster orchestration.
  • Excitement about building AI that simulates the world — and making it performant enough to run in real time.
  • Bonus if you have experience with torch’s compilation feature.

Benefits

  • Salary range based on competitive market rates for our size, stage and industry.
  • Pay equity for our team.
