• You don’t clock in for a paycheck; you clock in to outperform yourself in a high-frequency trading environment.
• You understand the stakes—milliseconds can make or break trades, and precision is everything.
What We Expect:
• Develop and maintain scalable backend systems using Python.
• Design and implement REST APIs and socket-based communication.
• Optimize code for speed, performance, and reliability.
• Collaborate with frontend teams to integrate server-side logic.
