Senior Data Infrastructure Engineer - Scale & Reliability

CaseGuild seeks a senior engineer to own, operate, and improve a major vertical of its distributed infrastructure in Seattle. You will design systems that stay fair, isolated, observable, and predictable under contention, and you will write production code, investigate performance issues, and manage production operations. The role emphasizes end-to-end ownership where there is no separate platform or SRE team; you will define infrastructure, deployment, observability, and incident response.
