MEMX operates a US equity exchange founded by a consortium of major retail brokers, global banks, and market makers. The tech stack is exchange-grade—Java, FIX protocol, low-latency networking (TCP/IP, UDP), and infrastructure-as-code (Ansible, Terraform, Chef)—with heavy infrastructure and security hiring (7 engineers, 3 ops, 3 security across 15 open roles). Active projects span trading platform development, low-latency network environments, and surveillance design, pointing to a mature exchange operator managing both regulatory compliance and performance-critical systems.
MEMX is a US stock exchange operator established in 2019 with a founding membership of major US brokers and financial institutions including Bank of America Merrill Lynch, Charles Schwab, Citadel Securities, E*TRADE, Fidelity Investments, Morgan Stanley, TD Ameritrade, UBS, and Virtu Financial. The exchange's stated mission centers on reducing trading costs, improving transparency, and simplifying equity execution in US markets. The organization operates on a partnership model and maintains remote-first operations with employees across the United States, Singapore, and Sri Lanka. Day-to-day operations require close attention to production stability, regulatory surveillance, and network performance across a distributed infrastructure.
MEMX's stack centers on Java for application logic, FIX protocol for market connectivity, and low-latency networking protocols (TCP/IP, UDP). Infrastructure is managed via Ansible, Terraform, Chef, and Jenkins for CI/CD, running on AWS and Azure.
MEMX actively recruits in the United States, Singapore, and Sri Lanka, operating on a remote-first model with no fixed headquarters.
