Job Description:

Machine Learning Engineer – London (Hybrid)

I’m working with a highly technical organisation in London that is looking for a Machine Learning Engineer who loves making things go faster.

This is an engineering focused role: take new ML technology, push it hard and find out what really works.

What you’ll be working on:

  • Getting hands on with new hardware and frameworks early
  • Improving the speed and scale of ML workloads
  • Solving performance problems that don’t have an obvious answer

What makes the opportunity interesting:

  • Exploration is a core part of the job, not a side project
  • Serious compute and genuinely hard engineering problems
  • Strong PyTorch skills valued over any particular background
  • A path to stay deeply technical

This would suit someone who gets a bigger kick from shaving milliseconds off a workload than from building the model itself.
