About the Role

Our Senior / Staff Site Reliability Engineer (Storage) is the connective tissue of Fluidstacks platform.

• Partner with engineers. Review designs, instrument new services and evangelise reliability patterns across product teams.

• Measure what matters. Define SLIs/SLOs that map directly to customer experience and build dashboards/alerts to track them.

• Drive continuous improvement. Identify tech debt, propose roadmap items and mentor engineers on reliability best practice.
