What the job involves

- As part of Kalshi, you will work on various platforms, including core exchange, clearinghouse, API infrastructure, connectivity to brokers and market makers, and others
- We are a small team, which means your responsibilities scale very rapidly, and your contributions are clear and visible, not marginal

- Provide the infrastructure to automate and standardize how software is built, versioned and deployed to target environments
- Provide infrastructure and tooling to automate test development and execution up and down the testing pyramid, including unit, API, and integration testing

- High guarantee and availability clearing systems, including margining, collateral management, and banking integrations

- Make decisions: we give a lot of flexibility, which also means no spoon-feeding
Our take
Despite there being a broad choice of investment models, traders have not traditionally been able to invest in the outcomes of future events. Kalshi, as the first federally regulated exchange where users can invest, trade and essentially "bet" on future outcomes, sets out to change this.
The company has launched a unique asset class called "event contracts", where investors can buy simple yes or no contracts based on whether an event will happen or not. Since gaining federal regulation, Kalshi has begun adding expertise in key areas, hiring new executive and director talent.
The key to the company's future will be maintaining trust with users through transparency, particularly on how more complex or ongoing ‘wagers’ are settled. The company is well-funded and continues to add options for its users. Although at present it is dealing with some not-so-great attention from regulators who believe it should be subject to gambling laws.
