Our 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 our specialty.
Deployment automation, scalable configuration management, and obsessive monitoring are the focus of some of our ongoing projects.
We automate as much of our work as we can, but not because we are lazy. We find that automation reduces our error rate and overall workload - plus, we think it's fun.
Working in our group provides opportunities for involvement with almost every other facet of the company. We 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 our custom monitoring tools, we strive to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.
We are looking to hire systems programmers and administrators with a deep knowledge of Unix internals and the Linux ecosystem.
Candidates should have a willingness to learn OCaml, our language of choice, and meet the following requirements :
