As an Nscaler, you’ll build trust through openness and transparency while contributing to the technology that powers the future. About the Role As a Principal/Staff Observability Platform Engineer, you'll own the technical direction of Nscale's observability platform: the systems that give us deep visibility into GPU clusters, AI workloads, and the infrastructure running them. You treat observability as a product and a discipline, not a tooling exercise. You'll set the architectural roadmap, raise the engineering bar across teams, and ensure our platform scales ahead of the business, not behind it. You understand that complexity is a cost. Solutions that require constant babysitting don't scale, and neither does operational burden. The platforms you build should be simple to operate, easy to understand, and self-evidently correct when something goes wrong. This isn't a "maintain and operate" role. It's a "define, build, and lead" role. What You'll Do Own the technical strategy and architecture for observability across metrics, logs, traces, and alerting at scale. Drive platform decisions that have multi-year impact: tooling, data models, ingestion patterns, retention, cardinality management. Identify systemic gaps before they become incidents; design platforms that make failure visible and fast to diagnose. Partner with SRE, infrastructure, and AI/ML teams to embed observability natively into how Nscale bui
