The Opportunity

Group One is looking for a technology generalist to join our Systems team. This role will be a hands-on position, and you will help manage and support all aspects of the firm's server infrastructure, which powers our proprietary trading platform. In addition, you'll have the opportunity to directly impact the servers and technologies that make up our complex distributed system by working collaboratively with our Systems team and our broader technology group.

Who We Are

We are committed to creating a diverse environment and are proud to be an equal opportunity employer.

Our system is proprietary, large, and multi-platform, so regardless of your current experience, there will be a lot of learning involved.
