Kalshi is defining 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.
Role Roadmap
We’re building a next-generation financial ecosystem — think NYSE or CME, rebuilt from scratch. As an Infrastructure Engineer at Kalshi, you’ll help design, build, and scale the systems that power our exchange, clearinghouse, API infrastructure, broker and market-maker connectivity, and more. We are a small engineering team, which means your responsibilities scale rapidly and your impact is clear, visible, and foundational. Much of our infrastructure is still greenfield, and entire systems can be yours to design and own.

Support clearing systems with high availability and strict guarantees, including margining, collateral management, and banking integrations
