Confirmed on the employer's own hiring board on Oct 16, 2026. First seen by Alion on Jun 25, 2026. Kalshi scores B on the Alion truth index.
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.

Iterating with designers to ensure an impeccable visual flow and continuity on the platform
Weighing customer feedback, business needs, and long-term goals to make product decisions
Working with marketing and business development teams to increase user engagement and satisfaction
What You Bring
4+ years of React experience and extensive TypeScript experience
Nice to haves: NextJS, and backend knowledge
Attention to detail and good UI/UX intuition
Interested in building frontends used by millions of users
Our Culture
Meritocracy is at our core, and we value people who take ownership and figure (usually hard) things out. We dream big. We love our craft deeply and are proud of what we put out in the world. We are committed to our vision of building something big… but also useful: a product that brings more truth through the power of markets.
Kalshians are Kalshi’s most important asset: we pick Kalshians carefully, so we trust them fully on day 1.
