What we're up to

Kalshi has launched the first regulated financial exchange that allows people to trade on the anticipated outcome of events. We’re now looking for the right people to help us continue to grow and scale.

Our vision is to allow people to capitalize on their opinions and hedge risks that relate to their everyday lives, from "Will CPI rise more than 0.5% this month?” to "Will 2023 be the hottest year on record?"

We're on a long journey in uncharted territories and are looking for passionate and outlier members excited to embark on this voyage towards building the future of the financial system.

Role Roadmap

As a backend engineer, you will help build and scale both the core exchange and other product backends at Kalshi.

Some of the projects you may work on:

  • Optimize order matching and trade execution algorithms and data structures.
  • Build high performance data feeds and trading API's for clients.
  • Work with our clearing partners as well as external market makers, brokers, and hedge funds to coordinate new features and performance improvements.
  • Improve and test the robustness and maintainability of our systems.
  • Optimize database access patterns and internal computations to improve the performance of the exchange.
  • Design new contract types and work closely with the product team to implement new member-facing features.

The company is launched and growing, which means your role will evolve and grow with the company. Joining Kalshi means you’ll be exposed to all parts of the business and define our culture and product paths.

Our Culture

We are a group of people who work hard and get things done, and we're looking for more people like that! Meritocracy is at our core, and we value people who take ownership and figure (usually hard) things out. We think of Kalshi as a family bound together by our mission: we believe that this is the best (and most fun!) way to work. Kalshians are, by far, Kalshi's largest asset and we're obsessed with growing and investing in our people.
