My client is a tech-centric prop trading fund, trading a wide range of financial products across the globe. Linux Engineers work with the critical infrastructure underlying the rest of the firm’s technology. Members of this group are hard-working Systems Engineers, Administrators and Programmers, tasked with maintaining and improving the platform that powers the production trading systems. The mix of in-house and open source software allows you to investigate and innovate at every level. On any given day, you could be debugging kernel performance, developing management tools, or resolving production issues in real time. Diving into tricky systems problems is their specialty.

Deployment automation, scalable configuration management, and obsessive monitoring are the focus of ongoing projects. They automate as much work as possible – not through laziness, but because automation reduces error rates and overall workload – plus it’s fun!

Working in this group provides opportunities for involvement with almost every other facet of the company. You’ll work directly with colleagues in Trading, Technology, and Operations to build and maintain systems with a firm-wide scope. Using feedback from other groups and custom monitoring tools, they strive to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.
