This is an opportunity to work at the intersection of high-performance engineering and digital asset markets, building and scaling a global trading platform that operates across dozens of exchanges worldwide.

- Interest in algorithmic or quantitative trading
Why Apply?
- Work on genuinely high-performance, real-time trading systems
- Significant ownership and responsibility early on
- Flat structure with direct access to senior leadership
- No legacy tech, no unnecessary bureaucracy
- Performance-based compensation with strong earning potential
- Central London office with flexible working arrangements (hybrid)
- Visa sponsorship and relocation support available
If you’re passionate about low-level systems, high-performance C++, and building robust trading infrastructure from the ground up, this is a rare opportunity to make a direct impact in a fast-moving market.
