Senior ML Systems Engineer

Machine Learning Systems Performance Modeller

Hands-on Technical Role at the Frontier of Large-Scale ML Infrastructure

We’re partnering with a well-funded, research-driven organisation to fill a critical position for someone passionate about performance modelling, distributed systems, and hardware-specific optimisations—with direct impact on architecture decisions at scale.


Responsibilities

  • Build simulation models that accurately represent:

    • Compute behaviour
    • Memory characteristics
    • Interconnect systems
    • Communication performance across large-scale ML systems
  • Develop proprietary tools for:

    • Simulating training and inference workloads
    • Emulating execution across distributed accelerator clusters
  • Model sophisticated distributed execution patterns including:

    • Collectives (e.g., Allreduce, Allgather)
    • Synchronisation mechanisms
    • Communication bottlenecks

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
