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.

  • Collaborate with cross-functional teams to integrate security measures into the overall system development life cycle.
  • Design and implement security controls to protect against unauthorized access, data breaches, and other security threats.
  • Monitor and respond to security incidents.
  • Stay abreast of industry trends, emerging threats, and best practices to continually enhance the organization’s security posture.

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.
