From the employer
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 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. Kalshi 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.
Building a new category is hard… like really hard. But it’s beautiful and deeply fulfilling. 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
As a Frontend Engineer, you'll be part of the SWAT team in charge of building the trading experience and user-facing platform of Kalshi. You won't just implement specifications, but instead, get to be part of the product development cycle and conceive entire features before developing. You'll engage with our user base and use your product intuition to build something they love. We're scaling, which means your role will evolve and grow with the company; your initial attack threads include:
- Building new features and flows across our web application
- Writing and maintaining frontend code to drive the product features
- 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
The rest of what the role looks like is up to you - a big part of our approach is that you get to chart your path as we grow and evolve. There's a lot of green field to conquer, we trust that you'll make a lot of it your own :)
About You
- 5+ years of React experience and extensive TypeScript experience
- Nice to haves: NextJS, and backend knowledge
- Attention to detail and good UI/UX intuition
