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

Traders at Exiorum run automated strategies. The job is to know exactly what the system is doing and why, and to change it when the market changes.

You own a book across one or more asset classes, work with researchers on new strategies and with engineers on how the system needs to behave.

What you will do

  • Run and monitor market making and systematic strategies across venues during the hours of your markets.
  • Set and adjust pricing, sizing and risk parameters as conditions change, and document why.
  • Analyse performance daily: fills, adverse selection, inventory, and what the P&L is made of.
  • Specify improvements to strategies and tooling, and test them before they go live.
  • Take part in the on-call rota for the venues you cover.

What we look for

  • Experience trading with real capital in an automated environment, or a very strong quantitative background with clear evidence of trading judgement.
  • An understanding of market microstructure: queue dynamics, adverse selection, inventory risk.
  • Working Python. Able to read the code that trades your book.
  • Calm and precise under pressure, including when the system misbehaves.
  • Fluent English.

Useful, not required

  • Options or volatility trading.
  • Digital asset perpetuals.
  • Exchange membership and clearing experience.
