At Citadel, a leading investor in the world’s financial markets, we aim to win together as one team to earn the long-term trust of our capital partners and each other. Our collaborative approach allows technologists to grow alongside other team members and execute on big, innovative ideas. 

Site Reliability Engineers (SREs) combine software and systems engineering expertise to build and operate the systems that power the firm’s investment strategies at the speed and scale required in fast-evolving markets. SREs are responsible for reducing complexity and improving performance in all corners of Citadel, providing early support for applications in development and ensuring crisp functioning of applications in production. 

Members of the Citadel SRE team have software development backgrounds and varied experience across production engineering, software quality metrics, chaos engineering, networking, UNIX internals, cloud application architecture, and much more.  A Citadel SRE’s work includes automation, instrumentation, optimization, incident response, and consultative support for other engineering teams. Crucially, Citadel SREs are commercial thinkers who partner closely with investment teams and enterprise functional teams to develop deep understanding of how applications work and to promote the SRE mindset, helping to build applications for stability and resiliency from their first stages.  

When you join our team, you will be part of a cohesive group of engineers and investment professionals who are partnering to build world class tools and systems. If you have a mind for innovation and automation and enjoy using measurements and statistics to drive constant improvement, we are eager to hear from you.
