Job description

One of the most exciting names in the space right now. Young, fast, and well-backed. Not a legacy shop protecting old edge — they're building new edge, and prediction markets are a priority, not a side project. They want to own this space before the rest of the street wakes up to it.

The opportunity

A ground-floor seat on a mandate that's still wide open. The edge is real, the field is thin, and whoever gets in now helps shape the whole effort.

Style-agnostic. Discretionary or systematic. Making or taking. What matters is that you can be consistently right when real money is on the line.

What you might be doing

• Trading event contracts across Polymarket, Kalshi and similar
• Building models for resolvable-outcome markets — elections, sports, macro, anything with a settled answer
• Providing liquidity and managing inventory across venues
• Finding edge in markets most of the street still doesn't respect

What sets you apart

• A real track record of making money in prediction or event-driven markets
• Sharp probabilistic reasoning and a feel for where the crowd is wrong
• Systematic: strong coding and modelling. Discretionary: judgement and conviction under pressure

On offer

• Top-of-market comp with upside that reflects what you generate
• Capital, infrastructure and autonomy to run your own book
• A firm that takes these markets seriously and moves fast
