The Role The Role Senior Site Reliability Engineer I (aka Senior SRE I) are experts in treating operations as a software problem. They focus on reliability of systems and services - addressing availability, performance, scalability, latency, observability, efficiency. They work on maintaining key components and developing systems that will minimize human labor (through automation) and increase system reliability with the end goal of breaking the relationship between system size, operational toil and complexity. A Senior SRE I is responsible for the design, prioritization and implementation of complex technical solutions. They can accurately estimate or forecast the effort and impact of the items they work on, and show a high quality of craft in what they deliver. They are expected to lead incident response for issues affecting their team. Senior SRE I is expected to coach and mentor less experienced engineers and be a thought leader in their team ensuring best practices are being implemented. The primary differences between a Senior SRE I and a Senior SRE II are the technical skills (enabling the Senior SRE II to only seek support in unique scenarios), the scope and the engagement in challenging best practices.Because the required technical skills and commercial knowledge can vary from one area to another, Senior SRE I can wear several hats; part of a business service owner team, owner of a piece of infrastructure, and/or consultant to product development teams regarding Site Reliability Engineering related scope.
