Lead Site Reliability Engineer - Imunify Reliability Platform

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Lead Site Reliability Engineer - Imunify Reliability Platform based in Belgium. This is a greenfield SRE leadership opportunity within a large-scale, security-focused product environment. You will define what “healthy” means across roughly 70 components spanning cloud services and customer-hosted agents. You will establish SLIs, SLOs, error budgets, monitoring standards, alerting, and escalation practices from the ground up. Your work will directly improve the ability to detect silent security-control degradation before it becomes a widespread customer-impacting issue. You will collaborate closely with engineering leads and senior engineers while building the telemetry and reliability platform yourself. The environment is remote-first, async, technically demanding, and focused on measurable outcomes rather than dashboards for their own sake. This is an opportunity to shape the reliability culture and foundations of a major security product.
