Trading System Engineer

About us


We are a young and highly profitable trading firm with a strong automation and technology focus. We trade our own capital and therefore do not need to prepare sales pitches or hold client meetings. Instead, we devote our time to improving the technology stack and scaling our trading to be faster and safer. All work gets done on a collaborative basis, and everyone can directly see the impact of their work on the business.


We trade on both traditional markets and are also extensively involved in the crypto space.
