Job description

We are seeking a highly skilled and visionary Principal/Lead Site Reliability Engineer (SRE) to spearhead our critical migration from legacy systems to the Epic platform. In this technical leadership role, you will act as the driving force behind our system resilience, designing end-to-end observability, and architecting fault-tolerant solutions across a highly complex, multi-layered ecosystem.

As a Principal Site Reliability Engineer, you will be responsible for building a SRE practice, monitoring and performance engineering best practices which will be aligned to our agile teams to help drive availability, resiliency and stability of Quest products, platform and services.

You will also be a partner with architecture, engineers, security, and operations to design and build reusable patterns to deploy reliable and resilient solutions.

Duties and Responsibilities:

• Analyze and resolve complex technical challenges to ensure a seamless and secure migration process.
• Translate functional business knowledge into robust, actionable observability strategies.
