Senior Director, Enterprise Reliability Engineering

Senior Director, Enterprise Reliability Engineering

The Senior Director, Enterprise Reliability Engineering is responsible for improving the reliability, resiliency, scalability, and operational excellence of Marriott's Data and Core technology domains. This role plays a critical part in Marriott's reliability transformation, shifting the organization from reactive, centralized operations toward engineering-owned reliability grounded in modern Site Reliability Engineering (SRE) and Dev Sec Ops  practices. This leader serves as a catalyst for change, partnering closely with product, engineering, platform, architecture, and security teams to embed reliability throughout the software development lifecycle.

Success is measured by measurable improvements in reliability outcomes, incident reduction, engineering adoption, and operational maturity rather than ownership of ticket queues or production support.
