Role Overview:
Itero Group is seeking a Senior Linux & Network Engineer with strong hands-on troubleshooting skills across enterprise Linux systems, IP networks, and highly available production infrastructure.
Key Responsibility Areas
- Act as a first technical point of response and primary customer technical contact during production incidents, owning the investigation from initial detection through service restoration and follow-up.
- Perform hands-on troubleshooting across the complete service environment, including Linux systems, IP networks, firewalls, Pacemaker/Corosync clusters, Galera database clusters, virtualization, applications, and customer connectivity.
- Diagnose complex Linux and network problems using command-line tools, logs, monitoring data, routing information, and packet captures using tools such as tcpdump and Wireshark.
- Troubleshoot routing, switching, firewall, VPN, TCP/UDP, performance, and connectivity problems, including packet loss, latency, asymmetric routing, and other service-impacting network conditions.
- Troubleshoot highly available Linux and database environments, including Pacemaker/Corosync and Galera, with issues involving quorum, failover, cluster communication, replication, synchronization, and recovery.
- Coordinate internal engineering teams, customers, network/data-center providers, and other third parties when additional assistance is required while maintaining technical ownership of the incident.
- Design, deploy, maintain, patch, harden, monitor, and improve Linux, network, clustering, and cloud infrastructure.
- Perform root-cause analysis, execute controlled production changes, maintain technical documentation, and develop Bash/Python automation to improve operations and troubleshooting.
Required Experience and Skills
This position requires an experienced engineer who can contribute independently in a production environment from the beginning of employment. Candidates must already possess strong hands-on Linux, networking, and troubleshooting experience. Candidates will be introduced to Etherstack-specific applications, architecture, and operational procedures; however, this role is not intended to provide foundational training in Linux systems administration, networking, high availability, or production incident response.
