The Platform Engineering team builds, secures, and operates scalable infrastructure for cloud-managed SaaS products with on-premises components deployed at customer sites.

The Site Reliability Engineering discipline keeps the platform stable and reliable, with a strong focus on service continuity and customer experience. It owns production reliability, service-level objectives, observability architecture, backup and disaster recovery, incident response, and resilience, and co-owns cloud security posture and runtime vulnerability management with Dev Sec Ops .

As Staff Site Reliability Engineer, you set the technical direction for reliability across regions and services. You own the reliability strategy, define the standards and mechanisms that guide production operations, and raise the bar through design leadership, operational discipline, and mentorship. You remain deeply hands-on by designing and operating observability platforms, defining and governing SLO programs, leading high-severity incident response, building resilience and disaster-recovery automation, improving reliability of stateful and streaming platforms, and creating AI Ops workflows for triage, remediation, and self-healing.

The work is driven by observability and automation, with a focus on detecting and fixing issues before customers are affected and using every incident to improve the system.

• Production reliability, SLOs, and error budgets — the reliability of production services end to end, including standards, governance, and escalation for Tier-1 and Tier-2 services.
• Observability architecture and standards — metrics, logs, distributed tracing, and profiles instrumented across production systems, with consistent platform-wide standards.
• Chaos engineering and resilience — failure-injection experiments and validation of recovery mechanisms in pre-production and production environments.
• Backup and disaster recovery — backup validation, disaster-recovery architecture, failover testing, and recovery verification against defined RTO and RPO objectives.
• Cloud security posture — cloud security posture management, runtime vulnerability detection, and configuration-compliance monitoring, co-owned with Dev Sec Ops .
• Data and streaming platform reliability — reliability engineering for Postgres, Redis/Valkey, Kafka, Open Search, and other critical stateful services.
• Capacity, efficiency, and AI Ops — resource rightsizing, predictive alerting, autonomous triage, remediation…
