Systems Software Engineer

Job Description

We’re Citadel, a worldwide leader in finance that uses next-generation technology and alpha-driven strategies to transform the global economy. We tackle some of the toughest problems in the industry by pushing ourselves to be the best again and again. It’s demanding work for the brightest minds, but we wouldn’t have it any other way. Here, great ideas can come from anyone. Everyone. You!Hope is not a strategy. Engineering solutions to design, build, and maintain efficient large-scale systems is a true strategy, and a good one. Site Reliability Engineering is an engineering discipline that combines software and systems engineering to build and run large-scale massively distributed, fault-tolerant systems. Practices such as limiting time spent on operational work, blameless postmortems and proactive identification of potential outages factor into iterative improvement that is key to both product quality and interesting and dynamic day-to-day work. Our culture of diversity, intellectual curiosity, problem solving and openness is key to our success. Our organization brings together people with a wide variety of backgrounds, experiences and perspectives. We encourage our teams to collaborate, think big and take risks in a blame-free environment. We promote self-direction to work on meaningful projects, while we also strive to create an environment that provides the support and mentorship needed to learn and grow. We're proud to be our engineers' engineers and love voiding warranties by taking things apart so we can rebuild them.We are seeking talented engineers skilled in the art of integration who understand the Agile mindset and Site Reliability Engineering philosophies, yet, not constrained by how “things are usually done" and are willing to decompose and reinvent systems, processes, and tools. We're looking for passionate engineers to build some of the largest compute services on the planet; if you possess that rare mix of depth in Development, Operations, Networking, and Systems Engineering then we are waiting for your application.
