Smarkets is an exchange platform for betting and trading on sport and politics. We operate two main consumer products - the Smarkets exchange and SBK sportsbook app - in the UK, US, and other global markets. Being a Software Engineer at Smarkets means working in high-performing teams that have control over the features they ship and the code they write. We have built a modern tech stack around Linux, Kafka, Postgres, and Kubernetes using Python 3, C++20, Rust, and React. The Smarkets platform is used by tens of thousands daily through the app, website or REST API. We are continuously developing new features for these platforms, or improving performance, scalability and usability in the backend.

Kalshi is a federally regulated financial exchange that allows investors to trade directly on the anticipated outcome of future events. Kalshi’s markets cover a wide range of topics including economics, international affairs, media and entertainment, climate/weather, and public health. Because Kalshi’s market topics can be more specific than other instruments like stocks or bonds, investors can get direct exposure to the events and trends that they are interested in. For example, a Kalshi market on whether a certain free trade agreement will be signed can help retail investors get exposure to emerging markets and fluctuations in international trade.
