The Department : Engineering
Gemini is regulated and licensed like a bank, but it’s run like a tech startup, and engineering is the core of the company. There’s a wide range of tough problems to solve at Gemini – from properly securing hundreds of millions of dollars worth of customer funds, to developing innovative new blockchain products, to finding new techniques to combat fraud, to shaving microseconds off our API response times, and everything in between.
All of Gemini’s engineers are able to work across the software platform, not just on their own specialization or sub team. We value a thoughtful, collaborative software development process, coupled with a pragmatic approach to problem solving and delivering software.

Work with our team of core trading systems developers to improve and expand the functionality of our matching engine, order entry mechanisms, and market data publication.

Reliability, fault tolerance, recoverability, throughput, and latency are what we look for in our systems.
