The firm

Exiorum is a proprietary trading firm in Lugano, founded in 2020. It trades its own capital: market making and systematic trading in equities, futures, options and digital assets.

40+ people. No outside investors. Everyone codes.

The role

The machine learning group works on prediction problems where the data is large and the horizon is short: order book state, trade flow, cross-venue signals.

The work is half modelling and half engineering. Models train on years of tick data on the GPU cluster and then have to run in production within a latency budget.

What you will do

  • Design, train and evaluate deep learning models on order book and trade data.
  • Build the data pipelines that turn years of full-depth captured data into training sets without leakage.
  • Make models run in production: quantisation, batching, C++ inference inside the latency budget.
  • Set up experiment tracking, evaluation and monitoring so that model drift is visible early.
  • Work with researchers and traders on which problems are worth the compute.

What we look for

  • Experience training deep learning models on large datasets, with results you can explain.
  • Strong PyTorch or JAX and strong Python. Working C++ for inference.
  • An understanding of time series, and of the ways financial data breaks the usual assumptions.
  • Comfort with distributed training and GPU performance work.
  • Evidence of capability: papers, competition results, or systems that ran in production.

Useful, not required

  • Sequence models on high-frequency data.
  • CUDA.
  • Inference latency work.
