Arctic Lake

Arctic Lake is a London-based fintech company that builds custom, ultra-low-latency electronic trading systems for tier 1 banks—an environment where milliseconds decide outcomes. Behind that is a flat, first-principles engineering culture that pushes the limits of hardware and software efficiency. Engineers own work across the entire product lifecycle: custom FPGA hardware acceleration, pioneering DLT solutions, and high-level application logic in Java, Python, and TypeScript. You'll ship mission-critical code from day one, with real responsibility and experienced engineers alongside you. For ambitious engineers seeking extreme learning velocity and high ownership, few environments compare.
