Site Reliability Eng

The Systems Reliability Engineering (SRE) team helps Imagineers create and deliver the

software solutions that power experiences in our theme parks and resorts.

Systems Reliability Engineers use a software engineering approach to architect, design, automate,

monitor, and build applications at scale. This includes operating and engineering software with close

business segment alignment to deliver platforms through efficient, effective and resilient architectures.

SREs are talented engineers that are focused on improving quality through a data driven approach:

instrumentation, automation, and functional/unit testing.

his position is for an experienced systems engineer eager to play an integral role on the Systems Reliability Engineering team for The Walt Disney
