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
Research at Exiorum starts from data and ends in production. You work on the full loop: hypothesis, simulation on tick history, a small live allocation, and scale-up if the live results match the backtest.
You own what you build after it goes live, together with a trader. There is no hand-off to a separate implementation team.
What you will do
- Research signals in order book and trade data across equities, futures, options and digital assets.
- Build and test strategies on the simulation platform, from intraday market making to multi-day systematic.
- Take strategies live with a small allocation and compare live behaviour to the backtest in detail.
- Improve the research library: features, fitting, evaluation and the tooling everyone uses.
- Work with engineers on what the trading system needs in order to express your ideas.
What we look for
- A record of original quantitative work: research, competitions, or trading with real capital.
- Strong statistics and probability, and the judgement to know when a result is noise.
- Fluent Python. Comfortable reading and writing C++.
- An understanding of market microstructure: queues, adverse selection, latency and its cost.
- Rigour about backtests: leakage, overfitting, transaction costs.
Useful, not required
- Options pricing or volatility work.
- Published research or competition results.
- Time on a live trading desk.
