Perm Position: Senior Platform Optimization & Observability EngineerLocation: Remote (EU)Duration: 6 months +Owns platform health design and the observability stack (e.g. ELK). Responsible for optimizing existing infrastructure, expanding the observability platform with APM and security capabilities, and migrating monitoring and security audit assets from Azure-native tooling to the new observability platform. Coordinates with the network engineer on DR optimization and firewall review.Key Responsibilities Optimize existing virtualization platforms (e.g. VMware, Hyper‐V, KVM‐based platforms such as Proxmox) – performance tuning, capacity planning, resource efficiencyOptimize storage performance, capacity, and cost efficiency in virtualized environmentsHarden platform security – secure configuration, attack surface reductionReview and optimize existing DR designs and recovery processes to reduce RTO/RPOReview and optimize firewall rules – identify unused or risky rules, align with security best practicesExpand the observability platform with APM and security capabilities, including Sentinel replacement POC executionMigrate queries, dashboards, and security audit reports from Log Analytics to the new observability platformOptimize log collection, retention, and analysis – reduce volume, implement cost‐effective logging without losing visibilityCoordinate with the network engineer on DR automation and firewall reviewRequired Skills Hands‐on experience optimizing virtualization platforms (e.g. VMware, Hyper‐V, KVM‐based platforms such as Proxmox)Experience reviewing and optimizing storage performance and capacity, including latency, throughput, and cost efficiency in virtualized environmentsStrong understanding of platform security best practices, system hardening, secure configuration, and reducing attack surfaceHands‐on operational expertise of leading observability platforms (e.g. ELK stack)Experience with ELK APM and security modules including APM agent deployment, SIEM detection rules (e.g. Elastic Security), agent fleet management, and security event correlationExperience migrating queries, dashboards, and security audit reports from Log Analytics to the new observability platform including KQL query translation and compliance reporting migrationExperience with advanced monitoring solutions focused on platform stability, resilience, and early issue detection, including proactive alerting and capacity‐related signalsExperience with security compliance scanning tools (e.g. CIS benchmark tools)Familiarity with compliance frameworks such as SOC 1, SOC 2, and C5Experience integrating patch management platforms for reporting
