Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of PhysicsX as an employer.

What you need

  • 5+ years of experience building and operating ML infrastructure at scale
  • Deep expertise in distributed training
  • Strong systems fundamentals: Linux, networking, storage I/O, profiling and performance optimization
  • Production experience with Kubernetes and SLURM for job orchestration on GPU clusters
  • Proficiency in Python and ML frameworks (PyTorch strongly preferred)
  • Experience with cloud GPU infrastructure

Nice to have

  • Experience with geometric deep learning or neural operators
  • Background in HPC for simulation engineering
  • Experience building model serving infrastructure
  • Familiarity with experiment tracking tools and observability stacks
  • Experience packaging models for deployment into customer environments

What you get

  • Equity options
  • 10% employer pension contribution
  • Free office lunches
  • Enhanced parental leave
  • YellowNest nursery scheme
  • 25 days of Annual Leave (+ Public Holidays)

Worth weighing

  • The role requires deep expertise in distributed training and strong systems fundamentals, which may limit candidates without this background.
  • The focus on ML infrastructure suggests a highly technical environment that may not suit those looking for a broader engineering role.
  • The posting emphasizes collaboration with research scientists, which may require strong communication skills in a technical context.
