The SRE team builds foundational backend services as well as tooling and automation to allow product teams to release and scale their software reliably and predictably. SREs are team players who embed themselves within product teams as needed to advance the architecture and performance of software systems and train their peers in topics such as debugging distributed systems, building self-healing applications and eking out every drop of performance possible.
