You’ll join as the first dedicated SRE hire, with responsibility for establishing SRE practices across a live Azure-based platform and a new strategic platform being brought into service.

The role is focused on reliability, observability, incident management, resilience, and automation. You’ll help define how services are measured and operated, introducing practical improvements around SLIs, SLOs, error budgets, monitoring, and service ownership.
