Kalshi is defining a new category

Kalshi has defined a new category: prediction markets. Kalshi allows people to trade on the outcome of any events & turn any question about the future into a financial asset. Kalshi fought for years & legalized prediction markets in the US for the first time in history. Kalshi is currently the fastest growing financial market in America, & has thousands of markets across politics, economics, financials, weather, tech, AI, culture & more.

We believe prediction markets have the potential to be the largest financial market because they turn anything into a financial position. 

• Our vision: well build the largest financial market on the planet. 

• Our mission: bring more truth to the world through the power of markets. 

Building a new category is hard like really hard. But its beautiful & deeply fulfilling. Our culture is simple: we hire really talented people, work really hard, & enjoy the climb. We are looking for ambitious & exceptional people to join our (relatively small) team to help us build the next generation of financial markets.

Role Roadmap

We are building a next-generation financial ecosystem (think NYSE or CME from scratch). As part of Kalshi, you will work on various platforms, including core exchange, clearinghouse, API infrastructure, connectivity to brokers & market makers, & others. We are a small team, which means your responsibilities scale very rapidly, & your contributions are clear & visible, not marginal. There is still a lot of green field at Kalshi & a low of it (including entire systems) can be yours.

What youll do

• Order matching & trade execution algorithms & data structures.

• High-performance data feeds & trading APIs for clients.

• High guarantee & availability clearing systems, including margining, collateral management, & banking integrations.

• Lead integrations with external market makers, brokers, & hedge funds.

• Stress test large-scale critical systems to ensure their robustness & maintainability.

• Optimize database access patterns & internal algorithms to improve the performance of our different services.

• Design new market structures (e.g., non-binary markets, scalars, futures, etc.).

• Be close to the customer (define features, ship products, iterate)! Even the backend can choose to be close to customers depending on the project.

• Ship fast & with high quality.

• Make decisions: we give a lot of flexibility, which also means no spoon-feeding.

The company is growing fast, which means your role will evolve & grow with the company. Joining Kalshi means youll be exposed to all parts of the business & define our culture & product paths.
