What is Kalshi?
Kalshi has defined a new category: prediction markets. Kalshi allows people to trade on the outcome of any events and turn any question about the future into a financial asset. Kalshi fought for years and legalized prediction markets in the US for the first time in history, is currently the fastest growing financial market in America, and has thousands of markets across politics, economics, financials, weather, tech, AI, culture and 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.
Our culture is simple: we hire really talented people, work really hard, and enjoy the climb. We are looking for ambitious and 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 and market makers, and others. We are a small team, which means your responsibilities scale very rapidly, and your contributions are clear and visible, not marginal. There is still a lot of green field at Kalshi and a low of it (including entire systems) can be yours.
What You’ll Do
Order matching and trade execution algorithms and data structures
High-performance data feeds and trading APIs for clients
High guarantee and availability clearing systems, including margining, collateral management, and banking integrations
Lead integrations with external market makers, brokers, and hedge funds
Stress test large-scale critical systems to ensure their robustness and maintainability
Optimize database access patterns and 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 and with high quality
Make decisions: we give a lot of flexibility, which also means no spoon-feeding

Bonus Points:
