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 India. 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. Define and establish meaningful SLIs for approximately 70 product components, working with squad leads and senior engineers to agree on ownership, measurement, tiering, SLOs, and error budgets. Develop a reliability taxonomy covering service availability and latency, fleet reachability and configuration convergence, security-control efficacy, artifact delivery, and telemetry pipeline health. Ensure reliability indicators are independently measurable and cannot be disabled by the same failure they are intended to detect. Design and build the telemetry collection pipeline for customer-hosted agents and cloud services, balancing push-based collection, sampling, privacy constraints, data quality, and cardinality. Extend instrumentation across Python, Go, and Rust components in collaboration with product engineering teams. Consolidate existing dashboards, queries, and reporting mechanisms into a smaller, more reliable observability platform, retiring tooling that does not provide meaningful operational value. Implement symptom-based, SLO-driven alerting with multi-window burn-rate principles and clear page, ticket, and dashboard classifications. Ensure every production alert has a defined owner, documented failure mode, and actionable runbook. Establish ongoing alert-quality practices, including periodic reviews, measurable actionable-alert rates, and deliberate removal of unnecessary alerts. Build a machine-readable ownership and escalation model that routes incidents to the appropriate engineering squads. Establish severity definitions, acknowledgement expectations, follow-the-sun escalation practices, and clean handoff procedures across multiple time zones. Strengthen incident command and blameless postmortem practices, including reliable timelines, ownership, and follow-through on corrective actions. Coach engineering squads to own their own operational responsibilities and paging rather than becoming a centralized buffer for other teams' alerts. Deliver measurable reliability outcomes over the first year, including complete SLI ownership, production telemetry, tiered alerting, squad on-call adoption, and a significant reduction in the time required to detect silent security-control degradation. Requirements Substantial production engineering or SRE experience, including experience defining and implementing an SLO framework rather than simply operating within an existing one. Strong Python skills and the ability to read and modify Go or Rust code when implementing instrumentation and reliability improvements. Strong hands-on experience with time-series and event telemetry at scale, including Prometheus/OpenMetrics, Grafana, Alertmanager-class routing systems, and columnar or high-cardinality data stores such as ClickHouse or equivalent technologies. Experience debugging distributed systems running on bare metal and long-lived hosts; this role requires more than Kube
