This role sits inside that team and owns test engineering for the work it ships, partnering closely with the peer engineering team that builds the agentic automation platform.   Role summary   As a Principal Software Development Engineer in Test, you own the quality bar for the Reliability Engineering function and act as the shift-left engineering partner across the wider application support organization. You are an engineer first and a tester second. You write code, you build test frameworks, you instrument quality signals into pipelines, and you raise the engineering standard for everything that ships through the team.   This is not a manual QA role and it is not a role that catches defects late. You move quality left into design reviews, code reviews, CI gates, and observability, and you build the automated test machinery that lets a small engineering team ship agentic runbooks, remediation logic, and operational platforms with confidence. You are the engineer the team relies on to make sure what reaches production has been engineered for verifiability from the start.   You partner with the senior reliability engineering leads, the agentic platform engineering team, and the senior architect. You are the single named owner for test strategy across your function, and the consulting voice on quality engineering across the wider
