SR.SRE; Linux & Windows

Overview

The Systems Reliability Engineering (SRE) team helps elevate SRE practices at TWDC, promoting and on-boarding new technologies, solving complex problems and integrating with next generation digital platforms.

Systems Reliability Engineers use a software engineering approach to architect, design, automate, monitor, and build applications s 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.

The Senior SRE will help create, build and deliver amazing experiences for our guests, fans and businesses. Primary responsibilities include helping existing, new and emerging business teams onboard technologies or platforms to accelerate their businesses. This will include consultation, designing, building, and supporting development pipelines, automating infrastructure and operations, creating telemetry for monitoring, engineering high reliability and reinforcing best practices to secure our company and guest data.

The Senior SRE is expected to have systems administration skills in Linux and Windows platforms, and must have experience with software development (e.g. Python, Go, Java, Node), CI Pipeline tools (e.g. Jenkins), Git source management, cloud hosting (AWS, GCP & Azure), container computing (e.g. Docker, OCI), web technologies and the Dev Ops team culture. This position will also bring a working knowledge on systems, network, operational excellence and application stability, security, performance, and capacity management, as well as documentation.

The Senior SRE must be prepared to work with engineering, creative and production teams in an extremely collaborative and high-energy environment to brainstorm, architect, gather requirements, troubleshoot, and provide stellar customer support. The ideal Senior SRE is passionate about constantly learning, applying technology to solve complex problems, and is a highly motivated, optimistic, proactive, creative thought leader and project manager.
